Nano device ‘times drug release’
US researchers say they have harnessed the power of gold nanoparticles to devise a better way of delivering drugs to treat diseases such as cancer.
The fledgling system could release a number of drugs in a specific part of the body at desired intervals, the MIT team wrote in the journal ACS Nano.
The device makes use of the fact that different particles melt when exposed to different levels of infrared light.
Different drugs on the particles could thus be released in a controlled way.
