Abstract

UV-nanoimprint lithography (UV-NIL) has been proved to be an efficient method for preparing nanodrug delivery systems. Herein, we used UV-NIL associated with the glancing angle deposition (GLAD) process of electron beam evaporation to prepare Au-coated PLGA nanocylinders loaded with PTX (PTX-PLGA-Au NCs) to enhance anticancer efficacy by the cooperative treatment of photothermal-chemotherapy. PTX-PLGA-Au NCs with different length-to-diameter ratios can be prepared by controlling the concentration of PLGA and regulating the angle of GLAD. Upon 808 nm near-infrared (NIR) irradiation, PTX-PLGA-Au NCs exhibit a stable and repeatable photothermal effect. Besides, hyperthermia generated by the Au layer on the surface of PTX-PLGA-Au NCs under laser irradiation promoted the rapid release of PTX. The in vitro studies demonstrated that PTX-PLGA-Au NCs can achieve the synergistic effect of photothermal-chemotherapy, leading to increased cell cytotoxicity. Therefore, UV-NIL combined with the GLAD process produced a promising nanofabrication method for efficiently developing a multifunctional nanoplatform for cancer treatment.

用于癌症光热化疗的紫杉醇负载聚乳酸乙烯雌酚/金纳米圆柱体

紫外纳米压印光刻（UV-NIL）已被证明是制备纳米药物递送系统的一种有效方法。在此，我们利用紫外-纳米压印光刻技术结合电子束蒸发的闪烁角沉积（GLAD）工艺制备了负载PTX的金包覆PLGA纳米圆柱（PTX-PLGA-Au NCs），通过光热化疗的协同治疗提高抗癌疗效。通过控制 PLGA 的浓度和调节 GLAD 的角度，可以制备出不同长径比的 PTX-PLGA-Au NCs。在 808 纳米近红外（NIR）照射下，PTX-PLGA-Au NCs 表现出稳定、可重复的光热效应。此外，在激光照射下，PTX-PLGA-Au NCs 表面的金层产生的高热促进了 PTX 的快速释放。体外研究表明，PTX-PLGA-Au NCs 可实现光热化疗的协同效应，从而增强细胞毒性。因此，UV-NIL 与 GLAD 工艺相结合是一种很有前景的纳米制造方法，可用于高效开发治疗癌症的多功能纳米平台。
