Abstract: The invention described herein provides methods for the detection of target particles, such as pathogens, soluble antigens, nucleic acids, toxins, chemicals, plant pathogens, blood borne pathogens, bacteria, viruses and the like. Also described is an emittor cell comprising a receptor, wherein the receptor can be an antibody or an Fc receptor, and an emittor molecule for the detection of a target particle in a sample wherein the target particle to be detected is bound by one or more receptors on the emittor cell. Also provided are optoelectronic sensor devices for detecting a target particle in a sample, including in a plurality of samples.

Abstract: Provided is an aerosol collector of reduced size having an aerosol inlet, an impactor plate containing several particle size-selecting nozzles therethrough, a replaceable collection layer and a fan having a power supply such as a battery pack, all of which fits a small container, attachable to, e.g., the lapel of the user, means to rotate the fan and move the aerosol through the sampler, so as to draw airborne particles through the inlet and through one or more nozzles, to impact the particles on the layer for analysis of same.

Abstract: An aerosol transport system. The aerosol transport system comprising a tube and having a plurality of windings that permit the flow of aerosols, including particles, there-through so as to compensate for gravity and/or centrifugal forces and reduce the settling of particles within said tube.

Abstract: Systems and methods for rapid thermal cycling in a polymerase chain reaction (“PCR”). Thermodynamic work is performed, directly, or indirectly, or both, on or by analyte and reagents comprising a PCR mixture. The thermodynamic work, which is typically adiabatic, reversible, and isentropic, causes a rapid and uniform change in the temperature of the PCR mixture. Consequently, the denaturing, annealing, and extension steps in the PCR procedure may be performed rapidly, uniformly, and with greater efficiency and higher throughput.

Abstract: A tool holding and positioning device for remote operation through a narrow opening is described. The tool holding and positioning device has a proximal end, an elongated first tubular member extending from the proximal end, and a distal end. A second tubular member is attached to the first tubular member for rotation about a fixed point adjacent the distal end thereof to position the second tubular member in a particular angle with respect to the longitudinal axis of the first tubular member. A first rod or cable is connected between the proximal end and the second tubular member for controlling its angular position with respect to the longitudinal axis. A second rod or cable is extended from the proximal end through the first and second tubular members to support and position tool means at a variable distance from the fixed point. The tool means are operatively connected to the second rod or cable and are controlled by control means operated from the proximal end.
