Abstract:
A method for screening analytes for a specific activity, chemical or physical property, or function, comprising the steps of:a) contacting an array comprising a plurality of different differentially responsive sensors with an analyte of interest comprising an activity, property, or function, wherein each of the pluraity of sensors in the array are responsive to a plurality of analytes having differing properties; b) measuring a signal output from each sensor of the plurality of different differentially responsive sensors; c) using the results of said measuring to obtain a signal profile related to a change in the signal output from each sensor; and d) comparing the signal profile to at least one previously-obtained signal profile obtained from a standard sample not including the analyte of interest and which has a known specific activity, chemical or physical property, or function, wherein such comparison is used to indicate a specific activity, function, or chemical or physical property of the analyte of interest.
