Hydrogels
Scientists have used gelatinous hydrogel to create an inexpensive new type of biochemical sensor that is highly sensitive, sturdy, long-lasting, and has few moving parts. The gel expands or contracts according to the acidity of its environment, a quality that allows the sensor to measure changes in pH down to one one-thousandth on the pH scale. This amount of accuracy, along with its robustness, could make it ideal for chemical and biological applications such as environmental monitoring in waterways and glucose monitoring in blood.

The University of Bradford, together with spin-out Advanced Gel Technology, is developing a cartilage repair gel that could delay the need for invasive surgery for five years or more. The hydrogel, which is not yet ready for clinical trials, is intended for traumatic injuries, including those sustained in car collisions or sports. Read More
