MICROORGANISM CONCENTRATION PROCESS AND DEVICE

摘要

A process for capturing or concentrating microorganisms for detection or assay comprises (a) providing a concentration device comprising (1) a porous fibrous nonwoven matrix and (2) a plurality of particles of at least one concentration agent that comprises a metal silicate, the particles being enmeshed in the porous fibrous nonwoven matrix; (b) providing a sample comprising at least one target cellular analyte; (c) contacting the concentration device with the sample such that at least a portion of the at least one target cellular analyte is bound to or captured by the concentration device; and (d) detecting the presence of at least one bound target cellular analyte.
