a TEM image and HRTEM (inset) image of BSe nanosheets. TEM images of Dex-BSe (b) and CS-BSe (c). d Scanning TEM image, corresponding cross-sectional compositional line profiles, and elemental mapping images of Dex-BSe. a–d Experiments were repeated three times independently with similar results. e Temperature elevation of Dex-BSe aqueous solutions with different concentrations under 808 nm laser irradiation (1.0 W/cm2, 5 min). f Photothermal cycling curve of Dex-BSe (400 μg/mL) upon NIR laser irradiation. g The temperature variations of PBS and S. aureus (105 CFU) culture media with BSe (205 μg/mL), CS-BSe (512 μg/mL) and Dex-BSe (512 μg/mL) under NIR laser, respectively. Data are presented as mean values±SD (n = 3 independent samples). Statistical significance was calculated by one-way ANOVA using the Tukey post-test. Source data are provided as a Source Data file.
