摘要： PROBLEM TO BE SOLVED: To provide a sensor array for detecting an analyte in a fluid.
SOLUTION: The sensor array comprises at least a first chemically sensitive resistor and a second chemically sensitive resistor electrically coupled to an electrically measuring device, and detects the analyte in the fluid. Each of these chemically sensitive resistors contains a nonconductive organic polymer and a conductive mixture having a composition different from that of the nonconductive organic polymer. Each resistor has an electrical path passing the nonconductive organic polymer and the conductive mixture, provides a first electric resistance when it contacts with a first fluid containing a first chemical analyte at a first concentration, provides a second electric resistance when it contacts with a second fluid containing the chemical analyte at a second different concentration, and is constituted so that the difference between the first electric resistance and second electric resistance of the first chemically sensitive resistor is different from the difference between the first electric resistance and second electric resistance of the second chemically sensitive resistor.

摘要： PROBLEM TO BE SOLVED: To provide (i) novel methods for preparing and using a plurality of compositionally different sensors, each of the sensor containing at least two different organic materials and capable of detecting the presence of a chemical analyte in a fluid; and (ii) new devices prepared by the methods. SOLUTION: The present invention provides a combinatorial approach for preparing arrays of chemically sensitive polymer-based sensors which are capable of detecting the presence of a chemical analyte in a fluid in contact therewith. The described methods and devices comprise combining varying ratios of at least first and second organic materials which, when combined, form a polymer or polymer blend that is capable of absorbing a chemical analyte, thereby providing a detectable response. The detectable response of the sensors prepared by this method is not linearly related to the mole fraction of at least one of the polymer-based components of the sensors, thereby making arrays of these sensors useful for a variety of sensing tasks.
