Apparatus to collect, classify, concentrate, and characterize gas-borne particles
First Claim
1. An apparatus for manipulating particles in an aerosol, comprising:
- a substrate;
an aerosol inlet for receiving said particles;
a gas moving means in fluid communication with said aerosol inlet, wherein said gas moving means is selected from the list consisting of a mechanical pump, a sorp pump, and a fan, said gas moving means for drawing some of said articles into said apparatus to form an aerosol stream; and
a UV laser light source mounted on said substrate after said aerosol inlet and disposed at right angle to said aerosol stream, said UV laser light source for illuminating said particles in said aerosol stream in order to induce a fluorescence response in some of said particles, said apparatus formed by micro-machining process.

Abstract
An aerosol lab-on-a-chip (ALOC) integrates one or more of a variety of particle collection, classification, concentration (enrichment), an characterization processes onto a single substrate or layered stack of such substrates. By mounting a UV laser diode laser light source on the substrate, or substrates tack, so that it is located down-stream of the sample inlet port and at right angle the sample particle stream, the UV light source can illuminate individual particles in the stream to induce a fluorescence response in those particles having a fluorescent signature such as biological particles, some of said particles. An illuminated particle having a fluorescent signal above a threshold signal would trigger a sorter module that would separate that particle from the particle stream.
