Researchers announce new temperature sensitve delivery system

Last week, researchers in the US and South Korea announced a new temperature controlled microbottle drug delivery system. The hollow, microscopic bottles are filled with the drug and a temperature sensitive cork like reactor, releasing the drug directly inside the body.

The researchers hope that the new system may allow for greater control of drug delivery. Cargo would stay inside the hollow polymer particle when plugged with a solid cork. When the cork is melted by body heat, the drugs would quickly flow out of the particle bottle.

The cork, made up of fatty acids, will control the rate at which the drug is released depending on the  temperature it takes to melt. Researchers also believe this system could be used to release temperature sensitive fragrances. What type of disease could a temperature controlled release system be used to treat?
