Abstract The simplicity and adaptability of self-assembled monolayers (SAMs) and the control over biomolecule surface orientation have begun to receive attention as a method of constructing electrochemical enzyme-sensors. This review provides the mechanism of forming SAMs, highlights two immobilization methods, the modification of electrode surfaces and the engineering of the enzymes, which can be used for constructing enzyme electrodes, and describes the recent development of fabricating electrochemical enzyme-sensors using self-assembled monolayer technology. Further research directions are suggested.
