MicroEnergy Technologies goal is to develop miniaturized, ultra-quiet, highly efficient biological collectors that can be interfaced with several aerosol detection approaches. The focus of this project is to develop the front end system for sampling and concentration of hazardous bioaerosols for subsequent detection using various downstream analytical procedures such as the many optical and wet chemical analysis techniques. The proposed miniaturized geometry provides a number of advantages, including, (1) ordered microstructures provide much lower pressure drop than randomly ordered fibers, (2) can be easily and effectively combined with electrohydrodynamic (EHD) driven flow to pull air through the system for extremely quite operation, (3) high collection and concentration efficiency of aerosols, and (4) high surface area for application of functionalized coatings to provide selective collection of both bioaerosols and chemical compounds of interest. The low-cost plug-and-play miniature sampling coupons are unplugged from the power and control module after sampling in the field, catalogued, analyzed in the laboratory, and properly disposed of (or archived) without the need to regenerate or clean the system. A low-cost miniature detection system will be integrated into the sampler unit for an autonomous remote sensing and data transmission unit. The development of man-portable noninvasive bioaerosol detection device will enable personnel to detect biological contamination for emergency response, law enforcement and military applications.
