Synthesizing green gold nanoparticles for cancer therapy with biomolecules

Scientists at Tokyo Institute of Technology (Tokyo Tech) have designed an eco-friendly protocol for synthesizing gold nanoparticles with optimized morphology for near-infrared light absorption using a biomolecule called B3 peptide. In their paper, they report the synthesis of triangular and circular gold nanoplates and their effectiveness in killing cancer cells by converting the absorbed light into heat, providing useful insights for the development of non-invasive cancer therapy.
