The primary aim of the Center for Bioelectronics and Biosensors is to create powerful, sensitive, and selective sensors - ranging from embedded systems to handheld devices - that can detect the presence of specific chemicals in the environment, or biomarkers in the body. The Center's research can be divided up into several key themes. Some of the technologies are focused on the detection of harmful chemicals that are a threat to the environment and human health. Others look inside the body for markers or presence of disease. Still others focus on the detection of human-made threats.
