Chemists from Trinity College Dublin, in collaboration with RCSI, have devised a revolutionary new scanning technique that produces extremely high-res 3D images of bones -- without exposing patients to X-ray radiation.
The chemists attach luminescent compounds to tiny gold structures to form biologically safe 'nanoagents' that are attracted to calcium-rich surfaces, which appear when bones crack - even at a micro level. These nanoagents target and highlight the cracks formed in bones, allowing researchers to produce a complete 3D image of the damaged regions.
The technique will have major implications for the health sector as it can be used to diagnose bone strength and provide a detailed blueprint of the extent and precise positioning of any weakness or injury.
