    摘要: A system and method employing optical disc drives for quantitative analysis of physical, chemical and biochemical parameters are provided. The system including a disc drive for supporting and rotating an optical disc including at least one sensor spot; a light source for directing light onto the sensor spot; at least one optical pickup for detecting light transmitted from the sensor spot, the transmitted light being indicative of a concentration of a compound; and an analog-to-digital converter for quantifying an intensity of the transmitted light. The method comprising the steps of preparing the optical disc with a plurality of sensor spots, the sensor spots being responsive to a compound; exposing the optical disc to a fluid; measuring intensity of transmitted light from at least one of the plurality of sensor spots; and correlating the measured intensity of transmitted light to an amount of compound exposed to the optical disc.

    摘要: A system and method employing optical disc drives for quantitative analysis of physical, chemical and biochemical parameters are provided. The system includes a robotic arm for transmitting a disc including at least one sensor spot through a variety of stations that include dipping the disc into a source of a compound, removing excess amounts of the source, optically scanning the disc, and discarding the disc. The optical drive may be a stand-alone reader in communication with an external computing device. The output of the optical scan may be transmitted from the optical scanner to the computing device via universal serial bus, Ethernet interface, or wireless connection.

    摘要: Methods are provided for improving the stability and shelf life of film sensors. The film sensors include a combination of polymeric matrix film material, analyte indicator, and solvent which has been heated in a first heat treatment application to volatilize most of the solvent and to solidify the analyte indicator to form the film sensor. The improvement comprises subjecting the film sensor to a second heat treatment to set the film and improve stability and shelf life.
