“…A hydrogel layer on the electrode surface can also serve as a solid electrolyte and buffer. [ 68 ] Wang and co‐workers showed the sensor for luteolin and baicalein detection. [ 69 ] The GC electrode was modified via the casting method with MWCNTs (multi‐walled carbon nanotubes) and poly( N ‐isopropylacrylamide‐co‐acrylic acid) (pNIPA‐AA) microgels.…”

The unique properties of smart hydrogels combined with conducting surfaces opened new possibilities in the construction of novel electrochemical devices. Electrodes modified with thin gel layers demonstrate the properties that are usually unachievable for bare electrodes. Usually a thin gel layer provides a highly permeable matrix for analytes, and can also serve as an immobilizing/impermeable matrix for larger molecules. Hydrogel barriers/layers are able to protect the electrode surface against the unwanted influence of the environment and to isolate the environment from the usually metallic, stiff, and hard electrode surfaces. A layer of hydrogel attached to the electrode surface can also serve as solid electrolyte, buffer and a reservoir for electroactive probes. In addition, the ability of smart gel materials to undergo a reversible volume phase transition related to significant changes in their volume and shape is very interesting from the point of view of the construction of switchable electrochemical systems. Such properties are strongly desired for the construction of various electrochemical devices. This review is focused on recent progress in the above field.
