Urea‐Urease Reaction in Controlling Properties of Supramolecular Hydrogels: Pros and Cons

Supramolecular hydrogels are useful in many areas such as cell culturing, catalysis, sensing, tissue engineering, drug delivery, environmental remediation and optoelectronics. The gels need specific properties for each application. arise from a fibrous network that forms the matrix. A common method to prepare is use pH change. Most methods result sudden jump often lead hard reproduce control. urease-urea reaction can be used control hydrogel by uniform controlled increase well set up cycles. involves hydrolysis of urea urease production ammonia which increases pH. rate with differing properties. Herein, we show how construction next generation functional materials.
