Preparation and Characterization of BDM. (A) Schematic diagram of the fabrication of BDM nanosheets. (B-D) TEM images of BP, BD and BDM. (E) Hydrodynamic diameter of BP, BD and BDM measured by dynamic light scattering. (F) Zeta potentials of BP, BD and BDM. (G) Absorption of DPBF in the presence of BDM (80 µg/mL) under irradiation (660 nm, 150mW) with different time. (H) Absorption of DPBF in the presence of BDM (80 µg/mL) under irradiation (660 nm, 5 min) with different power. (I) Photothermal images of BDM (80 µg/mL) in different times with laser irradiation (808 nm, 1.5 W/cm2). (J-K) Heating curves of BDM under different Concentrations and intensities. (L) Photothermal stability of BDM. All experiments were independently repeated in triplicate
