SENSOR SYSTEM AND METHODS FOR IMPROVED QUANTITATION OF ENVIRONMENTAL PARAMETERS

摘要

Systems and methods employing optical disk drives (202) for quantitative analysis of chemical and biochemical parameters are provided. A system (200) includes an optical disk (204) having at least one sensor region (205), a light source (208) for directing light onto the at least one sensor region, an optical detector (210) for detecting interacted light transmitted from the sensor region, the interacted transmitted light being indicative of a concentration of an environmental parameter disposed on the sensor region (205), and an analog-to-digital converter (220) for quantifying a measurable property of the interacted transmitted light. A method for preparing an optical disk (300) with a plurality of sensor spots (306) is provided. A system (1900) includes a robotic arm (1904) for transmitting the disk through a variety of stations that include dipping the disk into a source of a compound, removing excess amounts of the source, optically scanning the disk, and discarding the disk. A system (200) includes control software for directing the light source (208) and optical detector (210) to specified positions of the disk (204) during disk rotation, and for processing the sensor response data to display a map of the sensor material response, and to improve precision of the measured signal.
