The incubation and hydrothermal reaction under alkaline condition of bovine haemoglobin with chloroauric acid were investigated. The products in the supernatant from the centrifuge were found to be gold nanoparticles and carbon dots. Greigite (Fe 3 S 4 ) was found as a byproduct in the precipitation...
