Rapid Detection of Bacterial Count and Viability in a Microfluidic Device Using Electrical Impedance Spectroscopy

摘要

For a large number of applications in basic, clinical, food, and environmental microbiology, one is interested in detecting the presence of small numbers of bacteria (< 1000 per ml of sample) and in establishing their viability under conditions of interest. Traditional methods for doing so are labor intensive and take a long time ( 1 day or greater) to provide results.
