Summary
Abstract Herein, a mediated Gluconobacter oxydans biosensor was constructed by immobilizing the intact cells on the modified gold electrode. The surface was initially modified with gold nanoparticles and then, self‐assembled monolayers were formed by using 6‐(ferrocenyl) hexanethiol. Finally, G. oxydans cells were adsorbed onto the surfaces and the bio‐active layer was covered with a dialysis membrane. As well as the response characteristics, stabilities and substrate specificities ere investigated.
