Fluorescence-based method and a device for rapid detection of microbial contamination

摘要

A method for rapid detection of microbial detection is presented. It uses the reduction of resazurin to resorufin as an indication of the presence of viable cells. The method is highly sensitive (limit of detection 1 CFU/mL) and rapid (detection time 180 s). A portable device that could allow the detection to be performed in the field is also described.
