手机、防晒霜、太阳镜……纳米科技你已使用多少?

2017-08-30 14:31:24   新华网

纳米结构的电极材料可用来提高可充电电池的容量和性能,减轻电池重量,从而提高电动汽车这类交通工具的效能和续航距离。

此外,纳米技术还可用于水处理和污染物的清理。例如,二硫化钼薄膜等纳米材料能以更高效的过滤性促进盐水淡化,而多孔质的纳米材料可以像海绵一样吸收水中的重金属和浮油等有毒物质。此外,纳米纤维能够吸附空气中的微小颗粒,因此可用作净化空气的滤网。

纳米技术在环境治理中的应用还包括空气、水和土壤中污染物的检测。由于其独特的化学和物理特性,纳米颗粒对化学或生物试剂的灵敏度更高,因此可用在传感器中鉴别有毒物质,这比传统方法更加简单快捷,甚至能在检测的同时去除污染物。

更快的基因测序,更精准的癌症诊治

专家介绍,纳米技术对医疗和健康产业的影响日趋显著,并在药物输送、生物材料、造影、诊断、活性植入等医疗应用中得到稳步发展。

研究报告说,纳米技术在生物医学方面最引人瞩目的应用或许是被称为纳米孔基因测序技术的出现。其工作原理是利用电场驱动每个DNA单链穿过薄膜上纳米尺寸的孔,即纳米孔。当DNA单链通过纳米孔时,记录孔上产生的电流变化,从而识别出单链上的基因编码序列。该技术有望大幅降低基因测序成本并提高测序速度。

纳米技术另外一个富有前景的医学应用是药物输送。纳米技术能让药物突破化学、解剖和生理学阻碍,抵达病变组织,提高药物在病灶位置的聚集量,减小对健康组织的损害。例如,经过精心设计的纳米药物可经血管渗漏点渗入癌变组织,并在靶点位置积聚,从而提高癌症靶向治疗的精准度。

在医学造影方面,纳米颗粒因其尺寸微小和特殊的化学性质,可在特定组织和肿瘤位置形成积聚,从而实现更便捷、更准确的诊断,并提高治疗效果。

纳米科技还可应用于生物组织工程。石墨烯、纳米管、二硫化钼等纳米材料可用来制造支架,帮助修复或重塑受损的组织。纳米结构支架能够模仿组织特有的微观环境,促进细胞的附着、繁殖和长成,并诱导正常细胞机能及组织生长。
