Enzyme nanoparticles-based electronic biosensor

摘要

A simple and effective method to prepare an enzyme electronic biosensor by immobilizing enzyme nanoparticles directly onto the gold electrode surface is described; prepared horseradish peroxidase nanoparticles have been successfully used to develop reagentless electronic biosensors for H_2O_2 detection without promoters and mediators and offer great potential to develop enzyme-based electronic biosensors.
