Multi-stimuli sensitive supramolecular hydrogel

What is it about?

We reported here a novel three stimuli sensitive hydrogel which gives a smart response to the stimuli of temperature, light, and reduction, manifested in the form of a sol–gel phase transition.. This special multi-stimuli sensitive hydrogel has potential application in mimic natural biomaterials possessing intriguing biological functions for detecting external stimuli.

Why is it important?

Biological systems usually need to respond to different combinations of these stimuli. The materials possessing multiple responses may be excellent mimics of nature and have great potential applications. The obtained hydrogel in this work would give a smart response to the stimuli of temperature, light, and reduction; the response being manifested in the form of a sol–gel phase transition via responsive changes being induced in each of the stimuli sensitive groups.
