Abstract: An apparatus and method for detection of anything to which an antibody can be raised, or to which a chemical receptor can be fashioned, based on surface plasmon resonance. The apparatus and method have the capability to detect proteins, viruses, bacteria, toxins, pathogens, contaminants, chemical compounds, or nucleic acids based on surface plasmon resonance and surface receptor technologies which may include antibodies or chemical receptors. The device is field deployable and utilizes a single use sample holder card which includes the sample to be tested, test channels, waste reservoir and a functionalized test surface.

Abstract: A drug-delivery unit suitable for implantation into a patient body may include a valveless impedance pump. In some implementations the unit may include an actuator, control electronics and a battery, and may communicate with an external patient interface unit. The patient interface unit can be used to control operation of the implant and to download data from the implant. The patient interface unit can also be used to charge the implant and/or a separate charger can be used. In other implementations, a drug-delivery implant unit may lack internal electronics and instead rely on an externally-supplied magnetic field to actuate the pump.
