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...

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...

Nanotechnology is the study of the control of matter at the atomic and molecular level, and is focused mainly on the creation of materials and equipment to work within that scale. One thing holding back the advancement of this technology is the lack of experimental tools capable of visualizing nanoprocesses in real time across their full range of...
