Three-dimensionally Ordered Macroporous (3DOM) Gold-nanoparticle Doped Titanium Dioxide (GTD) Photonic Crystals Modified Electrodes for Hydrogen Peroxide Biosensor

The design and fabrication of simply,sensitively electrochemical biosensors have been of high interest for their widespread applications such as drug discovery,disease diagnostics,environmental monitoring and food safety.Using the 3DOM GTD/ITO electrode,we developed a new HRP-based H_2O_2 biosensor.This novel H_2O_2 biosensor displayed high sensitivity,acceptable stability and reproducibility.These provide a fundamental theory principle for the new biosensor application.
