具有独特纳米结构的半导体纳米晶体具有非凡的物理化学和生物安全特性,作为光热治疗(PTT)纳米敏化剂显示出巨大的潜力。本文中,我们成功地合成了手性钼(Cys-MoO 3-x)纳米粒子(NPs),以克服电子能带和生物毒性的一般限制。所获得的Cys-MoO 3-x NPs被选为通过半胱氨酸分子的装饰用于治疗口腔鳞状细胞癌(OSCC)细胞的理想设计,这是由于电导率和吸光度的优异的初始光热光谱分析。值得注意的是,NP具有作为可见光(VL)和近红外(NIR)双反应剂以消融癌细胞的能力。将光敏PTT与低毒性生物化疗相结合,在808 nm波长下,对口腔鳞癌细胞的体外治疗有效率可提高89%,并在VL照射下获得潜在的PTT效应,直观地证明了无毒的纳米粒子在激光照射下对癌细胞具有致死作用。因此,这项工作突出了一个强大的和安全的NP平台,用于近红外光触发PTT用于头颈癌(HNC)细胞,显示出良好的应用前景,在口腔肿瘤治疗。
Semiconductor nanocrystals with extraordinary physicochemical and biosafety properties with unique nanostructures have shown tremendous potential as photothermal therapy (PTT) nanosensitizers. Herein, we successfully synthesized chiral molybdenum (Cys-MoO3–x) nanoparticles (NPs) for overcoming the general limitation on electron energy bands and biotoxicity. The obtained Cys-MoO3–x NPs are selected as an ideal design for the treatment of oral squamous cell carcinoma (OSCC) cells through the decoration of cysteine molecules due to excellent initial photothermal spectral analysis of conductivity and light absorbance. Notably, NPs possess the ability to act as visible light (VL) and near-infrared (NIR) double-reactive agents to ablate cancer cells. By combining photoconductive PTT with hypotoxicity biochemotherapy, the treatment validity of OSCC cancer cells can be improved in vitro by up to 89% (808 nm) and get potential PTT effect under VL irradiation, which intuitively proved that the nontoxic NPs were lethally effective for cancer cells under laser irradiation. Hence, this work highlights a powerful and safe NP platform for NIR light-triggered PTT for use in head and neck cancer (HNC) cells, showing promising application prospects in oral tumor treatment.
