Enzymatic bioelectrochemistry represents the marriage of electrochemistry and enzymatic biocatalysis, and has  led to important applications for biosensors, biofuel cells, and bioelectrocatalysis. Enzyme immobilization is the  basis of enzymatic bioelectrochemistry, as immobilization itself determines the enzyme/material interface and  thus the electrochemical performance. Amongst the range of methods of enzyme immobilization, one-step  electrochemical approaches feature rapid immobilization and good control over the processes, enabling par?tial or total use of the electrode surface. In this mini-review, we first briefly introduce the operating principles of  bioelectrochemical applications based on enzyme modified electrodes. We then overview recent progress in  utilizing conductive polymers, redox-active modified polymers, sol–gel silica and electrochemically assistant  adsorption for enzyme immobilization via one-step electrochemical approaches. The use of conductive polymers  for in situ enzyme immobilization is our major focus. Perspectives for future work are also described.
