CNRS Paul Pascal Research Center in Bordeaux Researchers Design Smart Capsules That Release Their Contents On Demand

News-Medical -- How can an active principle be delivered in a controlled way? Until now, there was no obvious answer to this question. Now however, researchers at the CNRS Paul Pascal Research Center in Bordeaux have designed smart capsules that are able to release their contents on demand, simply by raising the temperature. Described in an article published on 2 February 2010 in the journal Langmuir, this novel system has just been patented. It opens up the way to many applications in a large number of fields such as food, perfumes and agriculture, for instance to deliver pesticides above a specific temperature.
