Fluorescent carbon dots were derived from Borassus flabellifer flowers by thermal pyrolysis method and used for label-free highly selective and sensitive detection of Fe3+ ions.
A novel paper-based chip that anchored zinc-doped carbon dots was constructed for sensitive and stable fluorescent detection of Cu2+. Zn doping increased the active sites for simplifying the modification of carbon dots.
