摘要

•One-step synthesis using thiosulfate yields gold nanotriangles with NIR absorbance.•Dimensions and properties of nanotriangles are adequate for photothermal therapies.•Nanotriangle surface covered by reduced sulfur species.•S-capped gold nanotriangles do not show toxic effect on fibroblast cells.
