0.2 mL of IR780-MNCs with a series of concentrations (0.5, 1.0 and 1.5 mg/mL IR780) was added to the cell plate. The infrared thermal images with relative temperature were captured by an infrared thermal imaging camera (Testo, Germany) under 808 nm laser irradiation (1.0 W/cm2) for 5 min.
The IR780-MNCs were placed in the sodium citrate solution (50 mM, pH = 5.5) for 12 h, then half of them were irradiated with 808 nm laser (1.0 W/cm2, 5 min). Afterward, the sample was dropped in the copper grid for TEM measurement to investigate the morphological changes.
