AuNRs photothermal treatment of inflammatory diseases; killing bacteria and viruses. A Cytotoxicity of AuNRs and PTT. (a) In vitro cell viability of Ana-1 cells, a mouse macrophage cell line, treated with or without various concentrations of the AuNRs for 24 h. (b) Cell viability of Ana-1 cells treated with or without the AuNRs (20 μg mL−1) after the NIR laser irradiation with different power densities (0, 0.5, 1, and 2 W cm−2). (c) Live cells and dead cells were stained with calcein AM (green) and PI (red), after incubation of Ana-1 cells with or without the AuNRs (20 μg mL−1) and being exposed to an 808 nm laser at different power densities (0.5, 1, and 2 W cm−2).
