Impedance-Based Detection of Bacteria

Abstract

Pathogenic bacteria have always posed one of the most serious threats to public health, and continue to be especially dangerous with the rise in antibiotic resistance. The prevalence of these infectious agents necessitates rapid, point-of-care sensors for their detection, identification, and monitoring. Electrochemical sensors are promising for the low-cost monitoring of bacterial growth and the detection of specific microbial species due to the consistency and ease-of-use of impedance measurements. Though the commercialization of these sensors is currently limited, they offer significant promise for detecting pathogens from real-world environments.
