1. A method for identifying a biological source, the method comprising: (i) collecting a plurality of bioparticles from the environment; (ii) selecting an information-rich bioparticle from the plurality of bioparticles; (iii) as part of the process for detecting a bioparticle signature from the information-rich bioparticle, restricting the movement of the information-rich bioparticle; (iv) processing a plurality of said bioparticle signatures into a multi-dimensional vector; and (v) identifying the biological source based upon comparison of said multi-dimensional vector to a standard multi-dimensional vector using a pattern recognition strategy.
