Micro- and Nanoscopic Imaging of Enzymatic Electrodes: A Review

The Cover Feature illustrates some of the efforts performed to investigate enzymatic electrodes at the micro- and nanoscale. Enzymes are extremely interesting molecules in the design of powerful bioelectrochemical devices. Among various techniques used to characterize their immobilization and behavior at the electrode surface, microscopy is the most adequate to offer spatially resolved information. This Review describes the microscopy methods used so far, ranging from scanning probe microscopy to study enzymes at the molecule level to fluorescence microscopy to characterize the whole bioelectrode.More information can be found in the Review by D.
