Figure 2

(A) Fourier transform infrared (FT-IR) spectra, (B) X-ray photoelectron spectroscopy (XPS) spectra, and (C) Ultraviolet-visible-near infrared (UV-Vis-NIR) absorption spectra of MoS2 NSs, MP NSs, MPP NSs, and MPPI NSs. (D) Photothermal heating curves of MoS2 NSs, MP NSs, MPP NSs, and MPPI NSs (MoS2: 30 μg/mL). All samples were irradiated under 785 nm laser at the power density of 0.43 W/cm2 for 10 min.
