The optically-cued electrospray aerosol selector (OCEAS), as proposed by MicroStructure Technologies (MicroST), and the Naval Research Laboratory (NRL), provide an innovative solution to achieving the challenging goals set by DHS. The goal of this project is to integrate an OCEAS design with a particle extraction module. Central to the OCEAS system approach is a fully automated particle sorting and novel particle extraction system from a dry collection surface. This project will build upon the success of the BIAD Sample Enrichment program by focusing on three major objectives. First, a 100 liter per minute (LPM) low maintenance axisymmetric virtual impactor concentrator (AxiVIC) will be refined and developed to support the fielding and maintenance program requirements required by DHS. Second, the bioaerosol particle sorting system or OCEAS will minimize the presence of background clutter and place selected aerosols onto a microstructured array. The particle sorting element further reduces OCEAS system maintenance by performing dry collection. More important to the program is the elimination of background clutter reduces the amount of fluid needed for extraction. Finally, MicroST will develop a particle extraction module where the particles will be extracted from a microstructured array into much less than 300 microliters of fluid.

The proposed project will develop a novel aerosol to liquid delivery system which combines a micro-fabricated aerodynamic lens (microADL) aerosol concentrator with a novel capillary collector to rapidly deliver large numbers of aerosol particles into nanoliter droplets. Mass production methods will result in a low cost, compact device with high throughput. In this project we will design a next generation microADL that can sample 100 slpm of ambient air and produce concentration ratios of up to 200:1 in a single stage device, and up to 2000:1 in a 2-stage device. We will develop a capillary collector that ensures 100% collection of aerosol particles; we will develop a droplet injection and transport system, and will identify capillary surface modifications and elution fluids to ensure 100% elution of the deposited aerosol particles or their DNA into the droplet, and we will demonstrate delivery of this droplet to a microfluidics detection platform. At the end of phase I, we will have demonstrated each of the critical elements of the overall system and we will have developed engineering and CFD models of these elements that can be used in phase II to optimize and design a fully functional prototype aerosol to liquid delivery system.
