摘要
Biology and medicine have seen great advancements in the development of enzyme nanobiosensors capable of characterizing and quantifying biomolecules. We provide an overview of mesoporous silica (MPS)-based enzyme nanobiosensors developed for biological and medical applications, and we describe significant advances in these technologies. We review progress in constructing high-performance electrochemical enzyme biosensors. We also discuss: WMCM-41 and SBA-15-modified and MPS composite electrodes for enzyme biosensing; incorporation of biorecognition elements into MPS material electrodes for enzyme biosensing; and, MCM-41 and SBA-15-supported electrocatalytic MPS-based electrochemical enzyme biosensors.
