Description

一种聚合物PLCL载药纳米纤维膜的制备方法
技术领域
本发明属于载药纳米材料的制备领域,特别涉及一种聚合物PLCL载药纳米纤维膜的制备方法。
背景技术
静电纺丝技术,即静电雾化或电喷的一种特殊方法,方法简单,成本低廉,是在电场作用下的纺丝过程,或利用高压电场实现的一种纺丝技术,通过在聚合物溶液上加高压静电,带电的聚合物液滴在针管形成Taylor锥,当电场力足够大时,停留在喷射头上的液滴就会克服表面张力形成喷射细流,最终在接收装置上得到纳米纤维膜。静电纺丝在过滤、组织工程、纳米复合材料、伤口敷料以及生物医药等方面具有许多潜在的用途。其中,用静电纺丝法制得的载药纺丝膜应用在伤口辅料上具有众多优势,例如纳米膜能有效的增大药剂的表面积;孔隙率高有利于细胞粘附和增殖;透气透湿性好利于细胞生长;形成多孔的纤维支架为伤口的修复和愈合提供良好环境等。一些纤维膜在药物载入后会起到一个药物缓释的作用,从而减少过量药物对人体的毒副作用。
聚乳酸己内酯(PLCL)一种脂肪族聚酯共聚物,由PLA和CL的开环聚合而成,通过改变PLLA和PCL链段的比例可以有效控制产物的断裂强度、断裂伸长和降解速率。选用合适的共聚物的组成既可以克服PLA材料的脆性,又可以很好的控制降解速率。可应用于软骨组织、骨组织、血管、尿路上皮组织、心脏组织等组织工程。
环丙沙星又名丙氟哌酸,对革兰氏阴性菌、革兰氏阳性菌、支原体等都有很强的抗菌活性。它是典型的两性化合物,C-3位含有羧酸基团,C-7位含有哌嗪基团,属于a-酮酸类物质,在酸性或碱性条件下加热均可发生脱羧反应。属于第三代氟喹诺酮类药物,这类药物包括诺氟沙星(NOR),恩诺沙星(ENR),和氧氟沙星(OFL)等。

(2)用5mL注射器抽取上述纺丝液,固定在静电纺装置上,调节纺丝参数进行电纺,喷出流速为1mL/h,静电压为14kV,接收距离为28cm,所处环境温度为25℃,湿度为40-50,纺丝时间为3h。待喷射稳定时,用铜网在喷丝处缓慢的上下移动三次,确定铜网上有纤维覆盖,将载有纤维的铜网室温下干燥24h。
(3)依照以上步骤将得到未载药的PLCL纤维膜,用场发射透射电镜(JEM-2100F)对铜网上的纤维进行观察,得到纤维的TEM图,如图1,从图中可见纤维表面光滑,无结节及串珠出现,且粗细均匀,纤维直径在600nm左右。
实施例2

(4)将收集到的纳米膜放入真空干燥箱25℃中干燥24h,即得到载药的PLCL纳米纤维膜。
(5)剪取1×1cm的干燥后纤维膜,进行傅里叶变换红外光谱的测试。
(6)依照以上步骤所得到载药PLCL纤维膜,PLCL纤维在1743cm-1和1450cm-1处分别有-COOC-和-CH2-的特征吸收峰,环丙沙星在1485cm-1、1628cm-1、1710cm-1、1580cm-1、1360cm-1处分别是芳香环、酮基、羧基、-COO--不对称收缩和-COO--对称拉伸的特征吸收峰,所得红外图谱如图2,在纳米纤维膜里均出现各特征峰,所以环丙沙星成功载到PLCL纳米纤维膜上。
