Nanoparticle drug delivery shows promise for the future of brain tumour therapy

A nanoparticle drug delivery system designed for brain tumour therapy has shown promising tumour cell selectivity in a novel cell culture model devised by scientists at The University of Nottingham. The project, conducted jointly by the Schools of Pharmacy, Biomedical Sciences and Human Development, will be featured in the September issue of the Experimental Biology and Medicine.
