研究人员利用病毒构建微电池元件

微电池电极组,每个电极的直径仅有4微米。

作为从普通感冒到艾滋病的各种疾病的始作俑者,病毒无疑获得了令人恐惧的恶名。但是,来自麻省理工学院(MIT;美国马萨诸塞州,Cambridge)的研究小组发现了病毒株的一种有益用途:研究人员通过遗传工程技术,诱使病毒吸附氧化钴分子,最终聚集形成可作为电池阳极的纳米线,这种电池的体积仅相当于人类细胞的一半。该过程中使用的M13病毒株不但对人体无害,还具有侵袭细菌的能力。

在发表于《美国科学院学报》的一篇文章中,这个小组对电池的阳极和电解液的聚集和测试过程进行了描述。来自MIT的Paula T. Hammond、Angela M. Belcher和Yet-Ming Chiang三位教授在文章中表示:“据我们所知,这是人类首次采用微接触印刷法装配和定位微电池电极,同时也是第一例以病毒为基础的装配过程。”

研究人员下一步将集中精力为这种电池开发阴极——同样利用病毒形成装配线。MIT教授Angela Belcher说道:“我们一旦成功改变病毒基因使其形成电极材料,我们就可以轻易克隆出数百万相同的病毒拷贝,用来装配我们的电池。”研究人员预计,基于这种技术的电池可用于从芯片实验室器械到植入式医用传感器等多种应用领域。Belcher 称,用这一技术生产出的电池具有生物兼容性,研究小组感兴趣的是如何将生物细胞集成到这种电池中。此外,这种电池还可压印到多数导电表面上。
