Silver nanoparticles (NPs) have attracted a considerable interest in the field of cancer research due to their potential utility in cancer therapy. In the present study, we developed bovine serum albumin (BSA)-coated silver NPs (BSA-Silver NPs) and characterized in vitro multimodal therapeutic activities of NPs for the treatment of skin cancer. BSA-Silver NPs were synthesized by a single-step reduction process, and the successful preparation was verified through a list of physical characterizations, including transmission electron microscopy (TEM), ultraviolet-visible (UV-VIS) light spectroscopy, dynamic light scattering (DLS), and Fourier transform infrared (FT-IR) spectroscopy. The synthesized BSA-Silver NPs showed marked cytocidal effects on B16F10 melanoma cells, which was likely caused by oxidative stress. BSA-Silver NPs also elicited significant anti-angiogenic effects on HUVEC (human umbilical vein endothelial cell) by inhibiting their proliferation, migration, and tube formation. Moreover, BSA-Silver NPs showed a considerable light-to-heat conversion ability, suggesting their utility as photothermal agents. Overall, our findings suggest that BSA-Silver NPs may be promising candidates for the multimodal therapy of skin cancer.
由于银纳米颗粒(NPs)在癌症治疗中的潜在用途,它们在癌症研究领域引起了相当大的关注。在本研究中,我们开发了牛血清白蛋白(BSA)包覆的银纳米颗粒(BSA-银纳米颗粒),并对纳米颗粒治疗皮肤癌的体外多模态治疗活性进行了表征。BSA-银纳米颗粒通过一步还原法合成,并通过一系列物理表征进行了成功制备的验证,包括透射电子显微镜(TEM)、紫外可见(UV-VIS)光谱、动态光散射(DLS)和傅里叶变换红外(FT-IR)光谱。合成的BSA-银纳米颗粒对B16F10黑色素瘤细胞显示出显著的杀细胞作用,这可能是由氧化应激引起的。BSA-银纳米颗粒还通过抑制人脐静脉内皮细胞(HUVEC)的增殖、迁移和管形成,对其产生显著的抗血管生成作用。此外,BSA-银纳米颗粒表现出相当大的光热转换能力,表明它们可作为光热剂。总体而言,我们的研究结果表明,BSA-银纳米颗粒可能是皮肤癌多模态治疗的有前途的候选者。
