We examine how the shape of cells and the geometry of experiment affect the reaction-diffusion kinetics at the binding between target and probe molecules on molecular biochips. In particular, we compare the binding kinetics for the probes immobilized on surface of the semispherical and flat circular cells, the limit of thin slab of analyte solution over probe cell as well as hemispherical gel p...

DNA microarrays provide an efficient means of identifying single-nucleotide polymorphisms (SNPs) in DNA samples and characterizing their frequencies in individual and mixed samples. We have studied the parameters that determine the sensitivity of DNA probes to SNPs and found that the melting temperature (T (m)) of the probe is the primary determinant of probe sensitivity. An isothermal-melting ...

Mercaptosuccinic acid protected gold nanoparticles (Au@MSA) self assemble to form superlattice (SL) crystals at the air-water interface. These have been used for gas adsorption. The current-voltage (I-V) characteristics of the SL film with embedded SL crystals, obtained by four probe measurements, show Ohmic conduction. The conductance observed was proportional to the polarizability of the adso...

13 A highly compliant, sensor-lined antenna probe can provide mobile robots with tactile information about immediate surroundings for exploration and localization. Analogous in structure and function to insect antennae, this type of antenna probe can be especially useful for feedback to highly dynamic and complex platforms such as fast running legged robots, providing direct information about t...

Electron energy distribution functions (EEDFs) have been measured in a cylindrical inductively coupled plasma (ICP) with a planar coil over a wide range of external parameters (argon pressure, discharge power and driving frequency). The measurements were performed under well-defined discharge conditions (discharge geometry, rf power absorbed by plasma, external electrical characteristics and el...

A single nanopore represents an amazingly versatile single-molecule probe that can be employed to reveal several important features of polypeptides, such as their folding state, backbone flexibility, mechanical stability, binding affinity to other interacting ligands and enzymatic activity. Moreover, groundwork in this area using engineered protein nanopores has demonstrated new opportunities f...

In a stacked package, typically the bottom package is processor and the top pa of additional applications required by consumer industry, IC engineers add more features to their 2 generation processor and the memory performance is increased by faster communication to the processor. Test engineers need a sock seen many product offerings for this one level stacked socket. In order to move from 1 2...

Susceptibility-weighted imaging (SWI) has continued to develop into a powerful clinical tool to visualize venous structures and iron in the brain and to study diverse pathologic conditions. It is a new art which evaluates and exploits the properties of blood, iron and other tissues. It is a magnitude or filtered phase images or combination of both, obtained with high-resolution 3D fully velocit...
