Recent Advances in Signal Amplification to Improve Electrochemical Biosensing for Infectious Diseases.

The field of infectious disease diagnostics is burdened by inequality in access to healthcare resources. In particular, "point-of-care" (POC) diagnostics that can be utilized in non-laboratory, sub-optimal environments are appealing for disease control with limited resources. Electrochemical biosensors, which combine biorecognition elements with electrochemical readout to enable sensitive and specific sensing using inexpensive, simple equipment, are a major area of research for the development of POC diagnostics.

Electrochemical Sensors to Detect Bacterial Foodborne Pathogens.

Bacterial foodborne pathogens cause millions of illnesses each year and disproportionately impact those in developing countries. To combat these diseases and their spread, effective monitoring of foodborne pathogens is needed. Technologies to detect these microbes must be deployable at the point-of-contamination, often in nonideal environments.
