科技部:我国纳米载体材料和诊断技术取得重大突破

2018-02-01 佚名 科技部

纳米载体材料和诊断技术是实现癌症早起诊断和治疗的重要技术,近日,纳米项目通过科技部高新司验收,显著提高我国重大疾病防治和健康产业发展的科技支撑能力。

癌症的早期诊断和治疗是医疗领域亟待解决的世界性难题,纳米载体技术和检测技术是重大疾病领域的重要发展方向之一,纳米生物医学对人民健康、社会和谐发展有着重要意义。“十二五”期间,863计划新材料技术领域支持了“面向重大疾病治疗的纳米载体材料及诊断技术”主题项目。近日,科技部高新司在北京组织专家对该主题项目进行了验收。

该项目研发了用于癌症治疗的硅质体纳米药物载体材料和靶向技术,优化了纳米载体结构并评价了生物安全性和药代动力学;开发了肝癌靶向聚合物基纳米载药系统,设计组装了形貌和结构可控的锌基纳米复合药物载药体系,实现了药物有效控释并完成靶向、药效及生物安全性评价;开发了纳米磷酸钙载药材料和载药可降解椎间融和器;研制出载银介孔硅纳米颗粒载体,实现了对活性抗菌成分的控释;设计制造出多喷丝头、多管并行小口径纳米纤维人造血管批量生产设备、仿天然多层结构纳米纤维人造血管;建立了光致发光材料及纳米微萃取材料在罪犯调查中的应用方法,并在犯罪现场勘测初步应用,研制出多种可用于心血管疾病和流感病毒检测的超灵敏快速定量检测试剂;初步建立荧光量子点快速检测研发体系。

“十三五”期间,为进一步推动我国新材料技术和重大疾病治疗领域科技创新和产业化发展,国务院印发了《“十三五”卫生与健康规划》,科技部制定了《“十三五”材料领域科技创新专项规划》,围绕新型生物纳米材料的研发,加强医学科学前沿的基础研究、关键技术研发、成果转化,启动面向2030年的健康保障重大工程,建立起相对完备的知识产权和标准体系,加快诊疗新技术、药品和医疗器械的研发和产业化,显着提高重大疾病防治和健康产业发展的科技支撑能力。
