Gold nanostars heavily loaded with DNA aptamers appear to be better at killing cancer cells than nanostars only lightly loaded with these therapeutic oligonucleotides. This new finding, from researchers at Northwestern University in the US, means that nanoparticles could be made into better anti-tumour agents simply by loading larger amounts of biomolecules onto them…..
