Photothermal and X-ray attenuation property of PEGylated WO2.9 NRs.
(a) UV-Vis-NIR absorption spectra of PEGylated WO2.9 NRs in aqueous solution (100 μg/mL). The inset shows the photographs of WO2.9 NRs dispersed in water, PBS and FBS, respectively. (b) Temperature increase as a function of the concentration of PEGylated WO2.9 NRs and irradiation time under the 980 nm laser irradiation (0.25 W/cm2). (c) Temperature change of the aqueous solution of PEGylated WO2.9 NRs (red: 750 μg/mL, black: 100 μg/mL) over five LASER ON/OFF cycles (0.25 W/cm2). (d) CT value (HU) of PEGylated WO2.9 NRs and Iohexol as a function of the concentration of tungsten (red) and iodine (blue), respectively. (e) In vitro CT images of PEGylated WO2.9 NRs (upper panel) and Iohexol (lower panel) with different W or I concentration.
