There is no current method for remote identification of aerosolized bacteria. In particular, such a capability is required to warn of a biological warfare attack prior to human exposure. A fiber optic biosensor, capable of running four simultaneous i

A new approach to producing SERS activity on dispersed particles is described. Silver islands are deposited onto submicron latex and glass particles, and the particles are dispersed into aqueous suspensions. The physical structure of the metal island

Effective defense against biological warfare (BW) agents requires rapid, fieldable and accurate systems. For micro- organisms like bacteria and viruses, ribosomal RNA (rRNA) provides a valuable target with multiple advantages of species specificity a

Analytical characterization of environmental sites has become a DLR1 to DLR2 billion dollar industry, and field methods to provide lower cost, more rapid analyses are being developed and commercialized. Antibody kits and fieldable gas chromatographs

DNA analysis based on template hybridization (or hybridization plus enzymatic processing) to an array of surface-bound oligonucleotides is well suited for high density, parallel, low cost and automatable processing. Direct fluorescence detection of l

Fluorescent and chemiluminescent detection of DNA hybrids on polymer membranes has been investigated using a cryogenically cooled, slow readout, two dimensional CCD camera in an imaging mode. The fluorescent background characteristics of commercially

An important consideration in the analysis of optical waveguide sensors (such as the fiberoptic fluorescent immunosensor) is the amount of total emitted fluorescence from the surface-bound proteins which is trapped and guided by the waveguiding struc

Evanescent fiber optic sensors are being developed for remote in situ immunoassay. The single reflection total internal reflection fluorescence (TIRF) geometry can serve as a well-defined model against which evanescent waveguide devices can be compar

Evanescent fiber optic sensors are being developed for remote in situ immunoassay. The evanescently excited fluorescence can be collected from either the proximal or distal end of the sensing fiber. The tradeoffs between the two directions of collect

Cone oil droplets are highly retractile, optically dense spheres located in front of the cone outer segment. Because of their refractile strength, absorbance, and size, these spherical oil droplets have a pronounced influence on the light reaching th
