TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
In stark contrast to current stagnation-based methods for capturing airborne particulates and biological aerosols, our demonstrated, cost-effective electrospray technology employs an entirely different approach based on the remarkable effectiveness of small, highly charged liquid droplets formed from an electrospray source to "getter" both particles and polar molecules dispersed in a gas. Less capable and expensive collection system technologies are generally based on stagnation of high velocity ambient airflow on a collecting surface. The momentum of particles and heavy molecules precludes their following gas streamlines during this stagnation. Instead, they concentrate and are trapped on the detector's surface if the surface is "sticky," or concentrated in the surface boundary layer, which can be separated from the mainstream flow and collected. Typically, current separation methodology collects about 50 percent of the particles between 1.0 and 10 microns in diameter from a flow of 500 L/min with a power consumption of up to 500 watts; i.e., about 1 watt of power is required for a small fan to compress 1 liter of air per minute to produce the high velocity airflow necessary for effective trapping of small bio-particles and heavy molecules. However, our electrospray technology consumes negligible power and achieves virtually 100 percent particle collection. In fact, we have demonstrated that the power efficiency of electrospray gettering for a single electrospray emitter to collect 100 percent of the particles, often without a fan, at 10,000 times greater than the power efficiency of state of the art systems.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Electrospray gettering may be applied to Building HVAC "Collect-To-Protect" applications for counter-terror protection, home HVAC use, automotive ventilation filtration applications, airplane air filtration, and submarine air filtration to name just a few commerical uses.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Spacecraft and spacesuit environmental particulate and hazardous chemical and biological species mitigation will be of paramount concern on future Moon missions and possible Mars exploration. The electrospray gettering technology can be used to continuously remove particulate and chemical species listed in NASA's SMAC list as well as aerosolized biological species, offering all the advantages of conventional electrostatic filtration methods but devoid of any ozone production and at far lower power requirements.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
