Scientists at the University of Southampton have developed smart nanomaterials, which can disrupt the blood supply to cancerous tumours. The team of researchers, led by Physics lecturer Dr Antonios Kanaras, showed that a small dose of gold nanoparticles can activate or inhibit genes that are involved in angiogenesis - a complex process responsible for the supply of oxygen and nutrients to most types of cancer. “The peptide-functionalised gold nanoparticles that we synthesised are very effective in the deliberate activation or inhibition of angiogenic genes,” said Dr Kanaras.
