Real-time near-infrared (NIR) thermal images of MoS₂-modified akermanite (MS-AKT) and AKT scaffolds at dry (a) and wet (b) environments under continuous irradiation of 808 nm laser at the power density of 0.50 W cm⁻²; The heating curves of MS-AKT and AKT scaffolds at dry (c) and wet (d) environment as a function of the irradiation time. The laser was shut off after 5-min irradiation at dry environments (a, c) or after 10-min irradiation at wet environment (b, d). MS-AKT scaffolds showed a strong photothermal conversion efficiency and could be rapidly and effectively heated up under 808-nm laser irradiation in comparison with AKT scaffolds.
