Reading up on the gold nano technology and it sounds fantastic. What it's supposed to do is (pls don't quote me on this) to find the MDR1 gene with transmembrane protein - called p-glycoprotein - which ejects/blocks cancer drugs. By finding this little 'nasty' - the choice of drug will be re-evaluated.
Still reading up on this. If anybody has more knowledge on this, please let me know? :-)
