Now, self-healing materials can mimic human skin, healing again and again

...out a composite matrix. When the material cracked, microcapsules would rupture and release healing agent. The healing agent then reacted with the embedded catalyst to repair the damage. “With repeated damage in the same location, however, the supply of healing agent would become exhausted,” said Scott White, a W...

'Biobullets' fight harmful mussels

... zoologist David Aldridge and colleagues developed microcapsules about the size of the algae particles that zebra mussels feed on. Once ingested, the "biobullets" slowly release small amounts of potassium chloride, a salt that is poisonous to most freshwater mollusks. Unlike other methods used to eradicate zebra m...

New 'self-exploding' microcapsules could take sting out of drug delivery

Belgian chemists have developed "self-exploding" microcapsules that could one day precisely release drugs and vac...could be given in a single shot with the "booster" microcapsules timed to rupture at appropriate intervals. ...
