Electrochemically erasable hydrogen-bonded thin films

摘要

We report a new method to trigger the dissolution of hydrogen-bonded layer-by-layer thin films through electrochemical reduction of dissolved oxygen, which raises the local pH.rnThe ability to dynamically control the properties of a surface, thin film, or hydrogel lends itself to a number of biomedical applications, including controlled drug delivery, biosensing, and separations, among others.
