Composite Silica-Based Films as Platforms for Electrochemical Sensors

Chem Rec. 2023 Sep 22:e202300194. doi: 10.1002/tcr.202300194. Online ahead of print.ABSTRACTSol-gel-derived silica thin films generated onto electrode surfaces in the form of organic-inorganic hybrid coatings or other composite layers have found tremendous interest for being used as platforms for the development of electrochemical sensors and biosensors. After a brief description of the strategies applied to prepare such materials, and their interest as electrode modifier, this review will summarize the major advances made so far with composite silica-based films in electroanalysis. It will primarily focus on electrochemical sensors involving both non-ordered composite films and vertically oriented mesoporous membranes, the biosensors exploiting the concept of sol-gel bioencapsulation on electrode, the spectroelectrochemical sensors, and some others.PMID:37737456 | DOI:10.1002/tcr.202300194
