    Controlling thermal conduction in semiconductor nanostructures
    For any electronic and optoelectronic devices, the energy efficiency is one of the most important factors. Even a highly efficient device loses some portion of the input energy by heat dissipation.Therefore,it can be a good strategy to recycle the wasted heat energy by the thermoelectric conversion to increase the total energy efficiency of the devices. My talk includes the background physics, research history, recent research trend of the field of thermo- electric conversion. Challenges for controlling thermal conductivity in nanostructured semiconductors, which is an essential factor for thermoelectric conversion, are introduced.

    Fabrication and novel physics of nano gap electrode/quantum nanostructure junctions
    Electrical manipulation and read-out of quantum mechanical states in single quantum nanostructures by nanogap metallic electrodes is expected to bring about great innovations in ICT devices. In this project, we will establish technologies of accessing to single mol- ecules and quantum dots by nanogap metallic electrodes and explore device applications of novel physics manifested in such nanogap junctions.

    Title : Non-porosity, Porosity, Multi-porosity: the Disordered life of Calix[n]arenes in the Solid-state
    Abstract:
    In this talk I will show that seemingly non-porous materials are highly porous and have very high stability towards absorption/desorption. Various types of porosity can exist not only in macro- scopic systems but even with regard to different types of channel in a crystal. If gases or volatile organics can flow rapidly into and out of solids what about fluidity in the solid state ?We will show in the complex of para-sulphonato- calix[8]arene with bipyridylethane there are separate channels for water and the bipy moiety but with intriguing differences in polarity. I will spend some time on high symmetry complexes and gas uptake. The work will be demonstrated by use of Surface Acoustic Wave sensors and will show how low one can get in vapor pressure. The hierarchical structures of the films used will be demonstrated.

    Title : Quantitative sequencing
    abstract
    Sequencers that can read millions of short nucleic acids in one day are revolutionising biology. It is expected that sequencing an individual’s genetic information will eventually cost less than 100,000 yens. But in addition to this qualitative use, the very high through- put of these new sequencers opens applications of quantitative nature, where the infor- mation is not only the sequences themselves, but the also the number of times they were observed. Sequencing technologies are now competing with microarrays and quantita- tive PCR in molecular biologists' experimental designs. After summarising the instru- ments available on the market and their usual applications, I will illustrate uses with two developments made at the RIKEN Omics Science Center. A) Using CAGE (Cap Analysis Gene Expression), we detect where the transcription of DNA in RNA starts on the chromo- somes, and use this information quantitatively to infer gene expression and reverse- engineer the cell's genetic program. B) By sequencing the antigen receptors of the T lym- phocytes, which are extremely variable as they are generated by the cells editing their own genome, we are studying how receptor use correlates with cell specialisation, open- ing the future possibility of monitoring the immune system's activity through a blood sample.

    Title : Graphene based NEMS: State of the art and perspectives
    Abstract
    Graphene offers an ideal starting material to realize electro-mechanical devices as it combines extremely low mass, very high young modulus (1TPa) and tunable electron charge density with excellent carrier mobilities. We present an experimental study of graphene membrane resonators obtained by the con- trolled under-etching of Graphene transistors. Actuation is realized by RF irradiation on the gate while measurement of the mechanical reso- nance is obtained by heterodyne frequency mixing followed by lock-in detection. The observed mechanical resonances for micron-scale doubly clamped membranes is of several tens of MHz with a quality factor exceeding 500 at room temperature and reaching 10,000 at low temperature. A DC voltage applied on the gate induces a mechanical strain within the mem- brane which allows to tune the resonant frequency on a wide range (typically 40-100 MHz ). The dispersion curves measured at different temperatures show that the built-in stress within the membrane determine the resonance properties. Perspectives for the cryogenic use of these devices in the superconducting state after controlled doping will be presented. Perpectives of operating these devices within the quantum regime will be discussed.

    Title : Organs ≪ on a chip ≫: Towards Predictive System Toxicology in Microfluidic Bioartificial Organs
    Abstract
    We will present a cell culture device for pharmacological and toxicological studies. At first the design issue will be introduced in order to create a microfluidic biochip allowing dynamic cell culture in a microenvironment configuration. Then, basic cell biological function will be characterized and we will show that hepatic cells main- tained liver specific functions when compared to classical well plates. To illustrate the microfluidic biochip potential, two examples of applications will be presented. In the first application we will show the interest of the biochip concerning the predictive toxicology and the related mechanistic interpretations. For that purpose, the cells have treated by acetaminophen (APAP). The results found in the biochip have reflected the specific toxic mechanism when compared to the conventional method due to a high Napqi biosynthesis. The transcriptomic and proteomic analysis of the APAP treatment have demonstrated similar biological processes affected in the biochip when compared to in vivo studies. As an extension of this work, we will present the potential of the biochip to identify specific biomarkers. In a second application related to pharmaceutical investigations and ADME-Tox studies, we will show the biotransformation capacity of primary human hepatocytes in microfluidic biochips. For that purpose, we have exposed the hepatocytes to a cocktail of specific probes of the key enzymes of the drug metabolism. The results show a higher biotransformation activity in the biochip compared to the traditional culture method. Thus, both examples will highlight the relevance of the microfluidic biochip in the frame of the development of alternative methods in predictive toxicology and ADME-Tox studies.

    Title : Physics and Rheology of embrionic cell aggregates: role of cytoskeleton and cell-cell adhesion
    Abstract
    It is now well known that embryonic tissues exhibit a complex fluid behaviour. Cell aggregates (or spheroids) made from dissociated and reaggregated cells or rounded explants are excellent systems to study these issues. The aim of our research is therefore to investigate whether changes in cell contractility independently of cadherin expression may also affect tissue surface tension. For this purpose, we are using different drugs affecting the cytoskeleton as well as cell lines derived from mouse carcinoma expressing cadherins whose link to the cytoskeleton has been impaired. We will present experimental results using biophysical methods to characterize quantitatively mechani- cal and physical properties of aggregates whose contractility have been modified under controlled conditions: tissue surface tensiometry, shape relaxation experiments, rheology experiments. The issue of cell-cell rearrangements in aggregates will be addressed from both 2-photons confocal experiments and modelling of stress-dependent tissue viscosity using an Eyring model.

    MEMS Manipulation/Characterization of Nano/Bio Objects with Simultaneous Imaging
    The author and his collegues have intensively investigated MEMS (micro electro mechanical system) design, fabrication and its application to nano and biotechnologies. Nano scientific research using MEMS devices covers the tensile and shear testing of nano contacts in transmission electron microscope (TEM) for in situ atomic level observation of the deformation of materials, and MEMS tweezers for capturing and characterizing DNA and other linear molecules electro- mechanically.MEMS for biotechnology includes microfuidic characterization of micro-organisms (Vorticella picta),micro- machined fL-chambers and heaters to allow single-molecular level enzymology, and the pick-and-place integration of biomolecular motors in MEMS for direct sorting and transportation of specific sample molecules. In this talk, I will focus on three topics; nano tensile/shear testing in TEM, MEMS tweezers for capturing and characterizing DNA molecules, and the nano transportation device that was built by pick-and-place assembly of biomolecular motors.

    16h10 : H. Kawakatsu (CIRMM, IIS, The University of Tokyo)
    Methods for measuring vibrations at the nanometer scale
    We report on various instrumentation issues related to friction measurement or lateral vibration measurement in tribological studies. One is the use of heterodyne laser doppler interferometry and photothermal vibration excitation, where commercially available atomic force microscopy (AFM) cantilevers could be made to oscillate both in the deflec- tion and torsional modes in the MHz regime. Structured water molecules could be imaged with molecular resolution at room temperature. The second method is the use of emission from vibrating molecules or nanometric structures. The origin of vibrating emission images on the phosphorus screen is identified.We will discuss the possibility of exploiting the measurement technique to measure the interaction of small oscillators and molecules with the environment in which they are placed.

    16h50 : Coffee Break

    17h00 : M. Lannoo (Scientific advisor at CNRS presidence, CNRS)
    Strategic approach to nanoscience and technology developed by CNRS
    We start by summarizing some key features for CNRS and the National plan for Nanoscience and Nanotechnology. We discuss the geographical repartition of the national and main local facilities.This is followed by a description of the role of the C’Nano which are interdisciplinary networks.The national financial support is compared to that of other countries in the world. We then come back to the situation at CNRS with its new organization and the need for a specific approach to interdisciplinarity which has led to the creation of a strategic unit in this field. We describe its role and its first achieve- ments. We end up by giving a short list of the main issues which are treated in the mixed CNRS ? University Laboratories.

    Title : When Photons listen to Phonons.
    Abstract
    How can light be used to generate and detect acoustic and thermal waves in solids? The principle of Picosecond Ultrasonics and Picosecond thermoreflectance is to use intense (100kW) and ultrashort (100fs) light train pulses as a hammer to produce a thermo acoustic perturbation in a nanomate- rial. A second light train pulses is used as a stroboscope to detect the surface motion or temperature with a sub picosecond time resolution. The thermal and acoustic spectrum can be monitored up to 2THz. The acoustic wavelength is in the order of nanometer. That allows this technique to be very well suited to micro and nano thermal physics, and nanomaterial physical properties measurement. The principle of Picosecond Ultrasonics and Picosecond thermoreflectance will be explained in simple words. Some applications to time resolved spectroscopy using a super continuum generated by a photonic crystal fiber will be presented. This kind of experiment can be used to generate and observe shear waves at picosecond time scale. This opens a new field for non-contact measurement, metrology and failure analysis in microelectronics. A few applications will be presented.

    Title : ‘’Fishing expedition’’ for biomarkers and modifiers of human neurodegenerative diseases

    Abstract :

    Past decade was marked by rapid advances in genome sequencing combined with an unprecedented development of novel research approaches to study biological systems in their complexity. A vast amount of genomic information and new tools such as gene expression microarrays triggered the call for a broad experimental design that includes a prerequisite and more extensive ‘’hypothesis generation’’ steps logi- cally connected with follow-up functional studies. This approach lead to the development of a new field of research generally referred to as Functional Genomics. Our research applies the tools and techniques of functional genomics to the studies of human neurodegenerative diseases such as Alzheimer’s disease. It focuses on the generation of whole genome expression data in health and disease, and filtering these data using functional studies in vitro and in vivo towards the identification of novel biomarkers, disease modifiers and drug targets. In this presentation, several recently completed and ongoing projects will be described with a focus on identification and functional validation of puromycin sensitive aminopeptidase (PSA/NPEPPS), a novel neuroprotective factor that specifically acts on neurotoxic misfolded proteins. Special emphasis will be made on current methods and experimental challenges used in this work. Download the Abstract

    Title : Single DNA molecule micromanipulation by magnetic tweezers : a tool to investigate enzymatic reactions.

    Abstract :

    In the last ten years, micromanipulation techniques have emerged allowing for the investigation of enzymatic reactions at the single molecule level. We use magnetic tweezers to pull and twist a micron size bead attached to one end of a DNA molecule by biotin/streptavidin while the second end is attached to a glass slide by digoxigenin/antibody. Monitoring the position of the bead with nanometer resolution allows us to record the minute changes caused by a single enzyme interacting with the DNA molecule ... Download the Abstract

    Title : Live cell-based sensor devices

    Abstract :
    InLiving cells maintain life functions by responding quickly and with great sensitivity to changes in the external environment. Consequently, sensors using cells as active elements are thought to be able to perform analyses faster and with more sensitivity than previously possible. We report here a live cells-based sensorchip fabricated in microfluidic channels in which several laminar flows were achieved. In addition, we established a cytotoxic sensor cell line, which was transfected with a green fluorescence protein (GFP) plasmid derived from the heat shock protein 70B’ (HSP70B’) promoter, which is induced by cytotoxic reagents. The fluorescence in the sensor cells increased in a CdCl2 dose-dependent manner in the microfluidic channels. In this system, cytotoxic reagents can be quantitatively detected in a quick, sensitive and high- throughput manner. The combination of sensor cells and microfluidic systems will provide an important basis for the development of micro-total analysis systems (micro-TAS) technology, and can be applied to toxicology, environmental assessment and drug screening.

    icon_pdf.gif Nanotechnology-based Cell Sheet Engineering for Regenerative Medicine

    Abstract :
    Here, we present unique tissue engineering without biodegradable polymer scaffolds, named cell sheet engineering. We first developed temperature-responsive culture dishes. A temperature-responsive poly- mer, poly(N-isopropylacrylamide), is covalently grafted on the surfaces. The grafted polymer thickness is controlled around 20 nm to achieve temperature-responsive cell adhesion/detachment control. The surfaces of temperature-responsive culture dishes are relatively hydrophobic at 37 degrees C similarly to commercially available tissue culture dishes, but changes to hydrophilic below 32 degrees C. Various cell types adhere, spread, and proliferate on the surfaces at 37 degrees C. Only by reducing temperature, cells are spontaneously lifted up from the surfaces without the need for trypsin. Confluently cultured cells are recovered as a single contiguous cell sheet with intact cell-cell junctions and deposited extracellular matrix. Harvested viable cell sheets can be transferred to other surfaces of culture dishes in vitro or tissue surfaces in vivo since the extracellular matrix associated with the basal side of cell sheets shows adhe- sion. The harvested cell sheets can be stratified to reconstruct thicker tissue architectures such as cardiac muscle and liver. We will demonstrate how to utilize these cell sheets for regenerative medicine including ocular surface reconstruction and cardiac tissue repair in clinical settings.

    icon_pdf.gif Carbon Nanotube, Nanoneedle and Nanomeniscus: mechanical and wetting properties of modified AFM tip apex

    Abstract
    Dynamic force microscopes (DFM) are very sensitive to variation of minute forces involved in the interaction between the tip and the surface. However, despite numerous efforts, imaging and probing mechanical properties of soft materials in air and water are still chal- lenging experiments at the nm scale. Among various factors determining AFM efficiency, AFM tip remains the central parameter and have been the focus of many creative ideas to improve its stability and resolution. Therefore any new developments able to improve the geometry and size of AFM tips were systematically investigated, in particular use of Carbon Nanotube (CNT), etching process, or Focus Ion Beam to carve a tip. The talk is divided in two parts. The first part is dedicated to the study of the air-liquid interface. We discuss the dynamical properties of a nanomeniscus wetting an oscillating nanoneedle. The second part is dedicated to study of carbon nanotube at the tip apex. As mechanical devices, carbon nanotubes (CNTs) can undergo large nonlinear deformations without permanent damage at the atomic scale.

    Abstract
    Microsystem platforms for co-culture of neuronal cells and for physiological analysis of cells will be presented. A microfluidic compartmentalized co-culture platform has been developed to study axon-glia communications in central nervous system (CNS). This microsystem allows co-culture of neuronal and non-neuronal cells while providing accu- rate control over positions of multiple cell types, localized chemical stimulation, and localized electrical stimulation. The second microfluidic system to be presented is for physiological analysis of cells based on single cell electrical impedance spectroscopy (EIS). The utility of this micro- system in identifying cancer cells and utilizing it for cancer heterogeneity analysis will be discussed.

    icon_pdf.gif Emerging micro/nanopatterning techniques for MEMS/NEMS

    Abstract
    Structuring silicon and related materials at micro and nanometer scale is typically done with sophisticated lithography and etching methods. For advanced micro- and nanosys- tems (MEMS/NEMS) more functional materials (complex oxides, nanocrystal polymer blends, and bio-molecules) need to be integrated at multiple length-scales (from nm to mm) and on a variety of substrates (including flexible polymer substrates). This is a grand challenge for surface patterning methods. Recently, alternatives to resist-based lithography have been developed. This talk will first give an overview of emerging nanopatterning methods and will then discuss in more detail two methods that are based on the local deposition of material, i.e. a vacuum-based high-resolution shadow mask process (stencil lithography) and a drop-on-demand dispensing of functional liquids by inkjet printing nanofabrication method.
