We present a new method of analyzing the deformability of fused cells in a microfluidic array device. Electrical stresses—generated by applying voltages (4–20 V) across discrete co-planar microelectrodes along the side walls of a microfluidic channel—have been used to electro-deform fused and unfused stem cells. Under an electro-deformation force induced by applying an alternating current (AC) ...

We calculate the optical properties of carbon nanotubes in an external static electric field directed along the tube axis. We predict strong Franz-Keldysh oscillations in the first and second band-to-band absorption peaks, quadratic Stark effect of the first two excitons, and the field dependence of the bound exciton ionization rate for a wide range of tube chiralities. We find that the phonon-...

The implications of organically-modified silica-based materials in electrochemical science is reviewed along with some selected recent trends in the field of functionalized and sol–gel silica electrochemistry. These recent trends include the electro-assisted generation of organosilica films on solid electrode surfaces, the preparation and applications of sol–gel derived composite (carbon, gold,...

Nan-fiber scaffolds are suitable tools for tissue engineering. Electro spinning materials together with cells presents not adequate to obtain a high cellular zing tissue constructs as the shear force, tensile force, and other physical effects excited in the electro spinning process, which are harmful to cellular differentiation, development and function. However, this limitation has been overco...

Human-cooperative robots (HCRs) are expected to benefit various industries, and many studies related to physical human-robot interactions have been conducted (Moore et al., 2003; Kim et al., 2005; Tsuji et & Tanaka, 2005); some HCRs have been gradually introduced in manufacturing and welfare fields. For instance, power-assist systems in manufacturing assist workers in carrying heavy modular par...

The present article draws a general picture of non-conventional methods for biomolecules immobilization. The technologies presented are based either on original solid supports or on innovative immobilization processes. Polydimethylsiloxane elastomer will be presented as a popular immobilization support within the biochip developer community. Electro-addressing of biomolecules at the surface of ...
