Abstract

A carrier having at least one kinetics and fluorescence enhancing support and a dry substance selected from the group consisting of fluorogenic substrates, B methylumbelliferone, 7-amino-4-methyl coumarin, B-napthylamine, fluoroscein, and resorufin deposited on the support demonstrates substantial enhancement of hydrolysis kinetics and fluorescence over pure liquid systems. When the device has a plurality of supports and the supports have different fluorogenic substrates an enzyme rate-of-reaction profile representative of a microorganism in the suspension can be determined and used to identify the organism. The device can also be used to characterize enzymes expressed by other biological specimens.
