Description
技术领域
本发明涉及生物医学工程技术领域,具体涉及一种生物医用胶带及其制备方法和应用。
背景技术
外科手术是临床治疗和控制大多数早期实体肿瘤的常用方法。然而,手术切除后的预后面临着几个棘手的问题,其中最具挑战性的就是肿瘤复发。举例来说,乳腺癌术后复发率在10%~41%之间,大多数复发患者还伴有肺转移或者脑转移,术后复发的患者死亡率高达90%以上。因此,为了提高生存率,防止肿瘤复发的研究一直在持续进行着。近年来,放疗和化疗已成为当前抑制肿瘤复发的术后治疗标准,然而,大量的文献报道了放疗和化疗伴随的并发症和副作用,如免疫抑制、肾毒性、心脏毒性等。因此,人们一直在寻求一种安全有效的肿瘤术后治疗策略。
光热疗法(PTT)是利用纳米填料的光热效应,通过近红外(NIR)照射进而杀死残余癌细胞,因其简单、微创、并发症发生率低,以及近红外光的高空间和时间精度等多种优点,吸引了研究人员的兴趣。为了获得更好的PTT性能,人们探索了各种纳米制剂,如金纳米颗粒(BioResources 2017,12,1982)和碳纳米管(Advanced Functional Materials 2019,29,1900554.)作为光热剂。然而,由于光热剂的生物降解性差等局限性,PTT的临床应用仍受阻。黑磷(BP)是一种新兴的二维层状结构纳米材料,具有较高的近红外吸收能力和较高的光热转换效率,更重要的是,BP纳米片由于其良好的生物相容性和生物降解性,在肿瘤领域的应用得到了广泛的关注。
然而,在氧气和/或水的存在下,BP纳米片的过快降解阻碍了其实际应用,因此,许多研究者将BP纳米片引入各种基体中制备复合材料。例如,Bowen Yang等人将BP纳米片集成到3D打印生物玻璃支架中,以改善其固有的不稳定性(Advanced materials 2018,30,1705611)。近年来,不同的材料被用作载体来负载功能纳米填料用于作为术后治疗的敷料,所述的载体如硅片、纤维、聚合物和水凝胶等。对于诸如肿瘤手术等外科手术的术后治疗的敷料,除了生物相容性和生物降解性外,还要求所用的载体基质具有合适的生物力学和粘附性,以保持治疗状态和位置,特别是后者。医用敷料在体内黏附性的主要障碍是材料与组织界面的水,其中的氢键会降低黏附效果,而黏附性不足则会引发治疗效应的偏移甚至对正常组织造成不良影响。
发明内容
有鉴于此,本发明提供了一种生物医用胶带及其制备方法和应用,以解决现有的用于术后治疗的敷料在生物水环境中黏附能力不佳的问题。
