 Research Interests

Our research has been focused on developing a number of methods for immobilizing biomolecules or their ligands on various electrode surfaces such as gold, silicon, indium-tin-oxide coated glass using chemical and electrochemical techniques. Electrochemical methods have also being developed to pattern surfaces into confined regions with biomaterials including protein and cell. The approach takes advantage of the presence of the electrode surfaces underlying the molecular layer, and the use of applied electrical potentials to effect electrochemical conversions of the molecular layer.

Over the past several decades, a great variety of biosensors have been extensively developed for the point-of-care (POC) diagnostics of a number of biomarkers. Especially an electrochemical detection is the most common one due to its high sensitivity, simple instrumentation, lost cost, and high portability, in terms of the signal transduction of the biorecognition events on the sensors’ surfaces. Our research has been also focused on developing highly a sensitive and selective detection method based on electrochemistry for POC.
