The fragmentation of gold nanoparticles induced by small biomolecules.
Spherical gold nanoparticles (3-5 nm) undergo a surprising fragmentation without extra energy input and are converted into ultrasmall particles (less than 1.5 nm), which is a direct result of electron transfer between gold nanoparticles and cysteine.
