Present day society is constantly demanding enhanced security for location and identification for both friend and foe. One avenue is biometric signatures, where standoff and clandestine systems are highly desirable. A biometric signature that holds great promise, but has not been exploited is biosignatures for subjects of interest gathered airborne...

Controlling drop movement on superhydrophobic surfaces is important in a number of technologies. For example, self-cleaning, superhydrophobic surfaces, microfluidics devices, and digital microfluidics can benefit from advances in developing non-wetting drops. To move water-based droplets, magnetic fields have been applied across a surface, but...

The field of microfluidics covers a broad range of applications that deal with the motion of fluids at a micro-scale. Microfluidic systems comprising nozzles, pumps, reservoirs, mixers, valves, etc., can be used for a variety of applications including drug dispensing, ink-jet printing and general transport of liquid, gases and their mixtures....

Tryptic digests with the subsequent analysis of the fragments produced are frequently used to characterize proteins. Such digests are limited by the amino acid specificity of the digesting enzyme (K and R in the case of trypsin). The analysis of fragments may also be complicated by self-digestion of the enzyme. The present invention provides a...

Lock in Amplifiers can extract signals from extremely noisy environments. This property can be put to use in improving the detection of signals in micro channels. In effect there is improvement in the signal to noise ratio hence increasing detection sensitivity in environmental and biological tests in miniaturized systems. There have are several...

Capillary Zone Electrophoresis (CZE) is a separation technique used for various analytical applications. It has been integrated onto glass substrates, microchips and in parallel with total chemical analysis systems, in order to provide efficient and informative results to its end user. Although CZE has developed into a highly regarded useful technique,...
