Biosensor Designs

Our biosensor designs: nano-clusters and nuclear magnetic resonance sensing platforms using antibodies and DNA fragments as biological receptors.

Type of biosensors we are currently working on:

1. Antibody-based biosensor (immunosensor)

2. DNA-based biosensor (genosensor)

3. NMR-based biosensor


Rapid detection of pathogens minimizes deadly organisms from infecting the population, contaminating the food chain, and polluting the environment. Beneficiaries of the technologies are patients, consumers, food industries, farm industries, tourism, and the homeland. Direct benefits to Michigan and the United States include a healthier population, safer food supply, cleaner water system, and more energetic work force. Such benefits will translate to a better society, economy, and environment.
