摘要

•Novel fluorophore C-dots pH indicator derived from natural Gadong (D. hispida) tuber.•C-dots from different tubers showed high reproducible physico-chemical properties.•pH sensitive carbon-based QD for fluorescence enzymatic biosensing of arginine.•Gadong starch-based C-dots considerably enhanced arginine optical biosensor response.
