Recent Developments for the Detection of Escherichia Coli Biosensors Based on Nano-Objects—A Review

Advances in nanotechnology have made it possible recent years to develop strategies for rapid and sensitive detection of pathogenic bacteria using new nanomaterials the development electronic nano-sensors. The still faces problems such as long analysis time complexity process. An alternative method is use biosensors, which combines a biological recognition mechanism with physical transduction technique. Thus, number methods manufacturing technologies been developed order achieve performance sensitivity, limit, label-free or real-time analysis. This review aims focus on state art biosensors elements Escherichia coli particular beneficial nano-objects detection. Among related based E. coli detection, measurement techniques are detailed by comparing their performances terms concentration range limit. Detection becomes more flexible nanoparticles markers, electrical dominant comparison optical ones. lowest limit can be achieved sensors metal (gold silver nanoparticles) contrast conductance.
