Scientists solve a sticky problem

Abstract:
A glue that can be switched on and off has been developed by British scientists.

The material loses and regains its stickiness when the acidity around it alters.

Scientists believe it could have important medical applications, with the body's natural acidity acting as a trigger for releasing drugs. The technology could also be useful in the design and control of micro-sized nanomachines.
