An enzyme cascade sensor with resistance to the inherent intermediate product by logic-controlled peroxidase mimic catalysis†
Abstract
Enzyme cascade sensors usually could not discriminate between the target and intermediate product. Herein, based on “AND” logic-controlled activation of the glucose oxidase–copper peroxide sensing system, enzyme cascade detection for glucose with resistance to inherently existing intermediate product H2O2 was reported for the first time, which may provide a novel way for facilitating enzyme cascade sensing.
