Polymer gels that can expand or contract by up to 1000 times in volume.

According to TECHTALK published by the MIT News Office, "Smart gels or polymer gels are a class of materials that expand or contract when triggered by tiny changes in temperature, light, a solvent or other stimulus."

Polymer gels have the ability to make large but reversible changes in volume allowing for the invention of smart gels that could deliver various agents and materials at specific events for countless purposes. For example, uses for smart gels could include cleaning up oil spills, creating cosmetics adaptable to skin pH, or even serving as miniature artificial valves and muscles.
