Non-toxic nanoparticles that can make radiotherapy more affordable and also minimise its side-effects in cancer treatment have been identified by researchers. An international team led by Royal Melbourne Institute of Technology (RMIT) studied alternatives to gold particles such as bismuth-based nanoparticles. Gold nanoparticles have been shown to concentrate radiation used in cancer but are highly expensive and mildly toxic according to an RMIT statement. Doctoral researcher Mamdooh Alqathami from RMIT said the team identified bismuth as an ideal option whose nanoparticles almost doubled the dose of radiation to surrounding cancerous tissue. ‘Bismuth-based nanoparticles are an attractive option as they cost
