Abstract

Traditional cancer therapies, such as chemotherapy, often lack specificity, resulting in severe toxic side effects and limited therapeutic efficacy. There is an urgent need to develop innovative multifunctional nanomedicine carriers that integrate precise diagnosis, targeted therapy, real-time monitoring, and the synergistic effects of multiple therapeutic approaches. In this study, a composite nanodrug delivery system (GO-HA-Ce6-GNRs) based on graphene oxide (GO) was innovatively prepared, which was functionalized with the targeting molecule hyaluronic acid (HA), the photosensitizer chlorin e6 (Ce6), and the photothermal material gold nanorods (GNRs). In vitro and in vivo experiments demonstrated that GO-HA-Ce6-GNRs exhibited excellent biocompatibility, remarkable photothermal and photodynamic properties, high drug-loading capacity for the anticancer drug doxorubicin hydrochloride (DOX), and a dual pH/near-infrared (NIR) light-responsive drug release profile. Additionally, GO-HA-Ce6-GNRs displayed enhanced tumor targeting and efficient fluorescence imaging capabilities. Notably, GO-HA-Ce6-GNRs@DOX manifested highly effective chemotherapy-photothermal-photodynamic synergistic anti-tumor effects in both MCF-7 and HeLa cancer cells as well as U14 tumor-bearing mice. Therefore, GO-HA-Ce6-GNRs@DOX represents a promising nanoplatform for tumor diagnosis and therapy, significantly improving the safety and efficacy of chemotherapy. This work provides a solid foundation and theoretical basis for the development of new targeted nano drug delivery systems that integrate both diagnosis and treatment.
在化疗-光热-光动力协同作用下用于肿瘤靶向诊断和治疗的多功能氧化石墨烯纳米药物递送系统。
传统的癌症治疗方法,如化疗,往往缺乏特异性,导致严重的毒副作用,治疗效果有限。迫切需要开发集精确诊断、靶向治疗、实时监测和多种治疗方法协同效应于一体的创新型多功能纳米药物载体。本研究以氧化石墨烯(GO)为基础,采用靶向分子透明质酸(HA)、光敏剂氯e6 (Ce6)和光热材料金纳米棒(GNRs)功能化制备了一种复合纳米药物递送系统(GO-HA-Ce6-GNRs)。体外和体内实验表明,GO-HA-Ce6-GNRs具有良好的生物相容性、光热和光动力学特性,对抗癌药物盐酸多柔比星(DOX)具有较高的载药能力,并具有双pH/近红外(NIR)光响应的药物释放谱。此外,GO-HA-Ce6-GNRs显示出增强的肿瘤靶向性和有效的荧光成像能力。值得注意的是,GO-HA-Ce6-GNRs@DOX在MCF-7和HeLa癌细胞以及U14荷瘤小鼠中均表现出非常有效的化疗-光热-光动力协同抗肿瘤作用。因此,GO-HA-Ce6-GNRs@DOX代表了一个很有前景的肿瘤诊断和治疗纳米平台,显著提高了化疗的安全性和有效性。本研究为开发新型的集诊断和治疗为一体的靶向纳米给药系统提供了坚实的基础和理论基础。

期刊介绍: Colloids and Surfaces B: Biointerfaces is an international journal devoted to fundamental and applied research on colloid and interfacial phenomena in relation to systems of biological origin, having particular relevance to the medical, pharmaceutical, biotechnological, food and cosmetic fields. Submissions that: (1) deal solely with biological phenomena and do not describe the physico-chemical or colloid-chemical background and/or mechanism of the phenomena, and (2) deal solely with colloid/interfacial phenomena and do not have appropriate biological content or relevance, are outside the scope of the journal and will not be considered for publication. The journal publishes regular research papers, reviews, short communications and invited perspective articles, called BioInterface Perspectives. The BioInterface Perspective provide researchers the opportunity to review their own work, as well as provide insight into the work of others that inspired and influenced the author. Regular articles should have a maximum total length of 6,000 words. In addition, a (combined) maximum of 8 normal-sized figures and/or tables is allowed (so for instance 3 tables and 5 figures). For multiple-panel figures each set of two panels equates to one figure. Short communications should not exceed half of the above. It is required to give on the article cover page a short statistical summary of the article listing the total number of words and tables/figures.
