与 DNA 分子一样,碳纳米管 (CNT) 可以表现出多种结构,但都可以传导电子并具有独特的光学特性。在这篇透视文章中,我们重点介绍了几件最近的作品,它们连接了这两个看似遥远的世界。我们通过探索利用纳米管半导体的几种正在开发的生物医学应用来说明碳纳米管在生物研究方面尚未开发的巨大潜力,包括将高灵敏度与选择性结合起来的场效应晶体管生物传感器,以及用于深层组织成像的荧光团,其激发和发射波长只需使用缺陷化学即可在整个近红外 II 窗口中进行调节。
Like molecules of DNA, carbon nanotubes (CNTs) can display a variety of structures, but all conduct electrons and feature unique optical properties. In this perspective article, we highlight several recent works that bridge these two seemingly distant worlds. We illustrate the largely untapped potential of CNTs for biological research by exploring several developing biomedical applications utilizing nanotube semiconductors, including field effect transistor biosensors that couple high sensitivity with selectivity, and fluorophores for deep-tissue imaging whose excitation and emission wavelengths can be tuned throughout the near-IR II window simply by using defect chemistry.
