Chemical Sensing

As part of MSGI Space Act Agreements with NASA, a revolutionary handheld diagnostic device has been developed with medical and environmental testing applications. This research has been conducted with support from the US Dept of Homeland Security, US Department of Defense and MSGI using breakthroughs in nanotechnology and chemical sensing. The new device plugs directly into an iPhone and can collect and analyze chemical data in real time. The device senses chemicals in the air using a "sample jet" and a multi-channel silicon-based sensing chip with a variety of nanomaterials. The device consists of 256 nanosensors on the chip and uses a pattern recognition algorithm to identify the "finger print" of the analyte of interest. The sensing device effectively learns the response pattern from changes in resistance correlated to concentration levels of certain target chemicals and gases.

Within the medical diagnostic field, the sensor will extract and test breath for a variety of biomarkers indicating various stages of a life threatening disease. The first such chemical sensor will be used as a non-invasive bloodless test for Diabetes, which has become the number one cause of death in many nations. Environmental diagnostic applications include testing the air in a burning building for levels of carbon monoxide and other dangerous or toxic gases, including attempts of bio-terrorism.
