SCNP-concentrations were set to (a) 0.1 mg/mL, b 0.2 mg/mL, c 0.5 mg/mL, d 1.0 mg/mL, e 2.0 mg/mL. f Temperature variations after each irradiation cycle. Photos of the 0.5 mg/mL solution during the measurement: g before irradiation, h at the end of irradiation, i after cooling down to room temperature.
