Abstract

Key findings

  • The composite mediator PVP-Os/chitosan exhibits enhanced electrocatalytic activity with glucose oxidase and lactate oxidase enzymes.
  • The bioelectrochemical behavior of the composite mediator is influenced by the type of enzyme used, with glucose oxidase showing higher current density.
  • The graphite electrode modified with the composite mediator and enzymes demonstrates improved stability and durability.
