Description
技术领域
本发明涉及一种微米微结构材料的制备方法,特别是一种空心微针阵列注射器的制备方法。
背景技术
透皮给药是无创给药的新途径,由于药物吸收不受胃、肠道等消化道的影响,避免了肝脏、胃肠道的首过作用效应,因此得到了国内外的广泛关注,具有广阔的市场前景。皮肤的角质层是药物进入肌体的主要屏障,因此透皮给药的关键是如何突破角质层并避免对皮肤的刺激。其中,微针阵列方法最受关注,即用微针穿透皮肤的角质层但未伤及真皮层进行药物传输。微针阵列制造的孔道是微米级的,比离子注入、电穿孔等方式所得的孔道更大,因此可以输运难以透皮的高分子、超分子甚至微粒,因此微针的制造方法一直是热点研究领域。早期的微针是实心的,在皮肤上留下一些孔道,药物沿着孔道扩散进入皮肤。最新的发展趋势是将微针与药物等的导入结合起来,形成空心的微针阵列注射器,物质沿着每个微针内部的孔道进入皮肤,这大大加强了药物分子和纳米粒子的输运效率,方便无痛地获得治疗所需要的药物与剂量。然而,目前空心微针阵列的制备主要依赖于昂贵的微加工技术,如反应离子束刻蚀、聚焦离子束刻蚀等,而且,为了预防感染、玷污等,微米针阵列通常都是一次性使用的,因此,上述方法不可能应用于市场可普遍使用的廉价空心微针阵列的制备,这极大地限制了其应用领域和范围。
发明内容
发明目的:本发明的目的是针对现有技术的不足,提供一种工艺简单、成本低廉的空心微米针阵列的制备方法。
技术方案:本发明所述的一种空心微针阵列注射器的制备方法,包括以下步骤:
(1)在微米微针阵列的表面包覆一层涂层;
(2)将微针端部开孔或部分去除;
(3)去除微针的内部模板,即形成空心微针阵列。
其中步骤(1)中,所述的微米微针阵列,其制备材料为无机物、有机物、金属,或合金;所述的微米微针的形状为锥形,或柱型;所述的表面包覆方法为涂覆,旋涂,溅射,拉膜,化学镀,电镀,PVD,CVD,或溶胶凝胶法;所述的涂层材料为无机、聚合物、金属、合金、或其任意组合;涂层厚度为20nm~500μm。
步骤(2)中,所说的将微针端部开孔或部分去除,其方法为切割、研磨、腐蚀、刻蚀、激光束轰击,或离子束轰击。
步骤(3)中,所说的微针的内部模板去除方法为煅烧、溶解、融化、刻蚀,或腐蚀。
有益效果:本发明的空心微针阵列注射器的制备方法与现有技术相比,工艺简单,对场地环境无特别要求;操作简便,制备周期短;极大地降低了空心微针阵列注射器的制备成本;不需微加工等昂贵复杂技术和设备,就可获得高质量的空心微针阵列;易于工业生产制备。
