Abstract
A biosensor was developed using oxidized cytochrome C - sulfite reaction by following the electrochemical reaction between reduced cytochrome C and gold electrode. The change in the current at the fixed potential equal to anodic peak potential of cytochrome C was proportional to sulfite concentration in the range of 0.4×10−4 to 4.0×10−4 M.Keywords
