“Nanoparticles ranging in size from 100nm to 500nm. The nanoparticles are used as a drug delivery carrier providing an inert support that stabilises the drugs and allows them to be released in a sustained manner once inside the body. They are made of polylactic-co-glycolic acid (PLGA) and can be introduced either orally or by injection.”
