鲨鱼皮帮助科学家对抗医院感染

Sharklet的表面图案模拟自鲨鱼皮的显微结构(上方所示),其在实验室测试中对于抑制生物膜形成的效果持续了21天。

由佛罗里达大学(美国佛罗里达州,Gainesville)研究人员成立的Sharklet Technologies公司(www.sharklet.com)开发出一种可减少医院感染的独特材料。研究人员的开发创意来自于他们对鲨鱼皮的探索,他们发现与鲸等移动缓慢的海洋生物不同,鲨鱼的皮肤上不会附着藤壶和海藻。研究表明,其奥秘就在鲨鱼皮上称为“小齿”的菱形显微结构,可以抑制有害菌生物膜的形成。

研究人员模拟鲨鱼皮的显微结构,开发出一种名为Sharklet的硅树脂材料。实验室测试表明,这种无毒的非析出性材料可有效对抗金黄色葡萄球菌、绿脓杆菌和大肠杆菌等细菌,而上述细菌是引起医院感染的常见原因。该公司运营副总裁Mark Spiecker说:“这是第一种能够抑制有害微生物生长的非杀菌性表面,无毒、长效。”

Sharklet可直接用于导管和其他侵入式医疗器械的表面。 实验室测试中,该材料抑制生物膜形成的效果持续了21天。而普通生物材料表面只需几小时就可形成生物膜。Brennan解释说:“需要注意的是这些结果均来自利用培养皿进行的实验室测试。而在临床环境下,这种表面甚至可能无限期延迟(生物膜的)形成。”

该公司希望明年可以面向医院和医疗器械企业销售这些材料。
