Electrofabrication of a low molecular weight hydrogel at high pH

Abstract

Fmoc-3 is a low-molecular-weight gelator that self-assembles to form hydrogels at basic pH. Here, using Fmoc-3, we show the first electrodeposition at high pH of a low molecular weight gelator using an electrochemically generated pH gradient. We also show that electrodeposition can be used to grow simultaneously two hydrogels at opposing pH extremes on different electrodes.
