Amperometric biosensors for the specific determination of ascorbic acid (AA) were developed by immobilizing ascorbate oxidase (ASOD) on a polyethylene glycol (PEG) modified silk fibroin (SF) membrane coupled to either the O2 electrode or the glassy carbon electrode (GCE). Both the O2 electrode and t...
