Herein, an efficient strategy to fabricate well-organized one-dimensional (1D) inorganic nanostructures is demonstrated by utilizing the hollow tobacco mosaic virus coat protein (TMVCP) as a restrictive template. Considering the advantages of the unique hollow structure and the dynamic self-assembly attribute of TMVCP, foreign nano-objects are successfully encapsulated and conveniently assembled into highly organized 1D chainlike structures in the cavity of the TMVCP multimer (TMV disk). Different kinds of functional nanoparticles, such as gold nanoparticles (AuNPs) and silver sulfide quantum dots (Ag₂S QDs), are used to demonstrate the successful construction of ordered 1D nanochains in high yields. Notably, binary nanochains of such different kinds of nanoparticles are also constructed through co-assembling the TMV disk-coated AuNPs and Ag₂S QDs. Further, the TMV-assisted AuNP nanochains are grown into the 1D nanowires through in situ Au deposition owing to the spatial confinement of the TMVCP cavity. Together, our findings indicate that the TMV-assisted self-assembly approach, resulting in higher yields and better controllability over the other reported studies based on directly mineralizing the metal architectures in the TMV nanorods, provides enormous potential toward the fabrication of highly complex hybrid-metal nanostructures.

空心烟草花叶病毒外壳蛋白辅助的一维纳米结构的自组装

在本文中，通过利用空心烟草花叶病毒外壳蛋白（TMVCP）作为限制性模板，证明了制造组织良好的一维（1D）无机纳米结构的有效策略。考虑到TMVCP独特的空心结构和动态自组装属性的优势，已成功地将异物纳米颗粒封装并方便地组装到TMVCP多聚体（TMV盘）的空腔中的高度组织的一维链状结构中。不同种类的功能纳米粒子，例如金纳米粒子（AuNPs）和硫化银量子点（Ag ₂S QDs）用于证明以高产量成功构建有序的一维纳米链。值得注意的是，这种不同种类的纳米颗粒的二元纳米链也可以通过将TMV圆盘涂层的AuNP和Ag ₂ S QD组装在一起而构建。此外，由于TMVCP腔的空间限制，通过原位Au沉积，将TMV辅助的AuNP纳米链生长成1D纳米线。总之，我们的研究结果表明，与其他基于直接矿化TMV纳米棒中的金属结构的研究报告相比，TMV辅助的自组装方法具有更高的产量和更好的可控性，为制造高度复杂的杂化材料提供了巨大的潜力。金属纳米结构。
