Researchers have discovered a new way to target and kill cancer cells in hard-to-treat brain tumours using electrically charged molecules to trigger self-destruction, that could be developed into a spray treatment used during surgery. A multidisciplinary team of researchers from the University of Nottingham, led by the School of Pharmacy found a new way to harness the extraordinary capabilities of bio-nanoantennae—gold nanoparticles intricately coated with specialised redox active molecules to induce programmed cell death, or apoptosis, in cancer cells on electrical stimulation.
