Abstract :
A hand-held instrument has been developed for microbial detection on surfaces and in water. Based on intrinsic microbial fluorescent markers, the instrument detects the presence of ~10 cells in ~2 cm2 interrogation area on a surface, such as meats/poultry, surgical tools and other sterile surfaces, and in water. Contact with the sample is not necessary for detection. Six intrinsic fluorescent markers are used simultaneously to determine the presence, quantity, and metabolic state (live/dead) of the microbial contamination. Detection requires seconds
