Abstract
The present invention provides unique methods and apparatus for the detection of an analyte of interest in a fluid sample by selective oxidation of the analyte into a carbonyl-containing compound followed by the controlled formation and growth of optically visible crystals as a qualitative and quantitative measure of the analyte. Epoxides, alcohols, olefins, arylalkanes and alkyl halides are among the many different classes or chemical entities which can be selectively detected in the concomittant presence or absence of other substances within the test sample.
