In this study, we present the preparation of stable 1T-WS2 ultrathin nanosheets with NH~ intercalation using a bottom-up hydrothermal method and the potential application of this material in light-induced photothermal cancer therapy. Our results revealed that nanosheets with a size of 150 nm were highly hydrophilic and exhibited strong light absorption and excellent photostability in the broad near-infrared wavelength region. The in vitro experimental results indicated good biocompatibility of the nanosheets. More notably, our in vivo antitumor experiments illustrated that light-induced photothermal ablation originating from irradiation of the 1T-WS2 nanosheets with an 808 nm laser could efficiently kill tumor cells; these effects were obtained not only at the cellular level but also in the living organs of mice. This result may lead to new applications of two-dimensional layered materials in novel photothermal therapies and other photothermal related fields. 展开更多

Herein,a facile and highly efficient synthetic method to prepare organic photothermal materials with high photo-stability and outstanding photothermal performance is reported.Through direct polymerization of commercial aromatic monomers in the presence of anhydrous aluminium chloride and dichloromethane,four kinds of conjugated microporous polymers(CMPs)were obtained.Detailed structural analysis confirmed that the resultant CMPs possessed abundant micropores with an extendedπ-conjugated skeleton.Under near-infrared(NIR)light irradiation(808 nm,1.0 W cm−2),all the CMPs showed fast heating-up behavior with their maximum temperatures higher than 150℃.Moreover,the efficiency of photothermal conversion(η)of the CMPs was found to increase linearly with the increase in the number of conjugated benzene rings within the monomer.Poly-TPE from tetraphenylethylene(TPE)and Poly-TP from o-terphenyl(TP)showed highηvalues of over 47%.Poly-TPE was additionally used as a photothermal filler to remotely and spatially control the shape recovery of thermal-sensitive shape memory polymers(SMPs),while its introduction(1 wt%)had little influence on the thermal and mechanical properties of the polymer matrixes.Owing to their excellent NIR photothermal performance as well as a one-step synthetic preparation,these CMPs may be promising photothermal materials for practical applications. 展开更多

Molybdenum oxide nanoparticles(NPs) with tunable plasmonic resonance in the near-infrared region display superior semiconducting features and photothermal properties, which are highly related to the crystalline and defective structures such as oxygen deficiencies. However,fundamental understanding on the structure-function relationship between crystalline/defective structures and photothermal properties is still unclear. To address this, herein,we have developed an "in-situ confined oxidation-reduction"strategy to regulate the defect features of molybdenum oxide NPs in the dual-mesoporous silica nanoreactor. Especially, the effects of crystalline structure/oxygen defects of molybdenum oxides on the photothermal performances were investigated by facilely tuning the amount of molybdenum resource and the reduction temperature. As a photothermal nanoagent, the optimal defective molybdenum oxide NPs encapsulated in PEGylated porous silica nanoreactor(designated as MoO_(3)@PPSNs) exhibit excellent biological stability and strong localized surface plasmon resonance effect in nearinfrared absorption range with the highest photothermal conversion efficiency up to 78.7% under 808 nm laser irradiation. More importantly, the remarkable photothermal effects of MoO_(3)@PPSNs were comprehensively demonstrated both in vitro and in vivo. Consequently, we envision that the plasmonic MoO_(3)NPs in a biocompatible porous silica nanoreactor could be used as an efficient photothermal therapy agent for photothermal ablation of tumors. 展开更多

Polymerization of amyloid-β peptide (Aβ) into amyloid fibrils is a critical step in the pathogenesis of Alzheimer's disease (AD). Inhibition of Aβ aggregation and destabilization of preformed Aβ fibrils have promising effects against AD and have been used in clinic trials. Herein, we demonstrate, for the first time, the application of WS2 nanosheets, to not only effectively inhibit Aβ aggregation, but also dissociate preformed Aβ aggregates upon near infrared (NIR) irradiation. Additionally, the biocompatible WS2 nanosheets possess the ability to cross the blood-brain barrier (BBB) to overcome the limitations of most previously reported Aβ inhibitors. Through van der Waals and electrostatic interactions between Aβ40 and WS2, Aβ40 monomers can be selectively adsorbed on the surface of the nanosheet to inhibit the Aβ40 aggregation process. Intriguingly, the unique high NIR absorption property of WS2 enables amyloid aggregates to be dissolved upon NIR irradiation. These results will promote biological applications of WS2 and provide new insight into the design of multifunctional nanomaterials for AD treatment. 展开更多

Glucose oxidase(GOx)-based nanotheranostic agents hold great promise in tumor starvation and its synergistic therapy. Self-assembled plasmonic gold vesicles(GVs) with unique optical properties, large hollow cavity, and strong localized surface plasmon resonance, can be used as multi-functional nanocarriers for synergistic therapy. Herein,GOx-loaded GVs(GV-GOx) were developed for light-triggered GOx release as well as enhanced catalytic activity of GOx, achieving programmable photothermal/starvation therapy. Under near-infrared laser irradiation, the GV-GOx generated strong localized hyperthermia due to plasmon coupling effect of GVs, promoting the release of encapsulated GOx and increasing its catalytic activity, resulting in enhanced tumor starvation effect. In addition, the high photothermal effect improved the cellular uptake of GV-GOx and allowed an efficient monitoring of synergistic tumor treatment via photoacoustic/photothermal duplex imaging in vivo. Impressively, the synergistic photothermal/starvation therapy demonstrated complete tumor eradication in 4 T1 tumorbearing mice, verifying superior synergistic anti-tumor therapeutic effects than monotherapy with no apparent systemic side effects. Our work demonstrated the development of a light-triggered nanoplatform for cancer synergistic therapy. 展开更多
