Electrochemical Microfluidic Biosensor for E.coli Detection

Microfluidic electrochemical biosensor based on Loop-mediated Isothermal Amplification (LAMP) was developed for detection and quantification of E.coli. The electrochemical detection was achieved using Hoechst 33258 redox molecule and linear sweep voltametry (LSV). Here, we detect and quantify 48 CFU/ml of bacteria in 35 min in LB media and urine samples. This microfluidic chip has great potential to be used as a point of care diagnostic (POC) device for clinical application.
