Mediator-free phenol sensor based on titania sol–gel encapsulation matrix for immobilization of tyrosinase by a vapor deposition method

A novel amperometric phenol sensor was constructed by immobilizing tyrosinase in a titania sol–gel matrix. The tyrosinase entrapped sol–gel film was obtained with a vapor deposition method, which simplified the traditional sol–gel process and avoided the shrinkage and cracking of conventional sol–ge...
