WS2 nanosheets were prepared by the solvent-thermal method in the presence of n-butyl lithium, then the exfoliation under the condition of ultrasound. The formed WS2 nanosheets were conjugated with thiol-modified polyethylene glycol (PEG-SH) to improve the biocompatibility. The nanosheets (WS2-PEG) were able to inhibit the growth of a model HeLa cancer cell line in vitro due to the high photothermal conversion efficiency of ∼35% irradiated by an 808 nm laser (1 W/cm2). As a proof of concept, WS2-PEG nanosheets with the better X-ray attenuation property than the clinical computed tomography (CT) contrast agent (Iohexol) could be performed for CT imaging of the lymph vessel.
The WS2-PEG nanosheets have the high photothermal conversion efficiency and show a good X-ray attenuation property.Figure optionsDownload as PowerPoint slide
