Medical treatment based on Nb₂C. a Schematic diagram of two-dimensional Nb₂C used in photothermal treatment of tumors. b S-NIR absorption spectra of different concentrations of Nb₂C NSs aqueous suspension. c Photothermal curve of Nb₂C NSs aqueous suspension irradiated by 808 nm near-infrared light irradiation at different power densities. d Blood circulation lifetime of Nb₂C − PVP after intravenous injection into mice. e Temperature elevations at the tumor sites of 4T1-tumor-bearing mice in groups of NIR-I, NIR-II, Nb₂C − PVP + NIR-I and Nb₂C − PVP + NIR-II during laser irradiation. f Time-dependent tumor growth curves after different treatments (control, Nb₂C − PVP only, NIR-I, NIR-II, Nb₂C − PVP + NIR-I and Nb₂C − PVP + NIR-II).
