SAP NTs was synthesized and demonstrated to exhibit intrinsic peroxidase and catalase-like activity.
The structure of SAP NTs provides larger surface area and more favorable medium for electron transfer.
Horseradish peroxidase immobilized on Au-Pt nanotube/Au-graphene acted as enzymatic biosensor.
The simultaneous detection of BHA and PG in food matrices was achieved based on enzymatic biosensors.
