Outline of Final Research Achievements

We have developed a multi-analyte sensing platform based on bipolar electrode (BPE) array device to realize small size, power saving, highly sensitive, and rapid screening system. BPE array allows wireless controlling individual　redox reactions at conductive plate. Autonomous and novel large-scale multi-analyte sensing system is designed, by addressing various combination of different types of biomolecules, including nucleic acids and proteins, and redox couples with different electrode potentials. Electrochemical bioimaging instrument we have developed has been applied for mapping of localized surface charge or current.
