Pump it: Materials that show intriguing shape changes induced by simple light exposure are emerging as candidates for artificial muscles. Recent examples are highlighted to illustrate the various molecular conformational changes induced by irradiation. Assemblies of these photoresponsive molecules are now being prepared that show functions that resemble real muscle.
