DNA功能化胶体的自组装

Self-assembly of DNA-functionalized colloids

Panagiotis E. Theodorakis, Nikolaos G. Fytas, Gerhard Kahl, Christoph Dellago

摘要:

接枝有单链DNA(ssDNA)链的胶体颗粒可以自组装成许多不同的晶体结构,其中ssDNA链的杂交在胶体之间产生稳定其结构的连接。根据颗粒的几何形状和大小、ssDNA链的接枝密度以及DNA序列的长度和选择,可以制造许多不同的晶体结构。然而,理解这些因素如何协同地促进DNA官能化纳米或微米尺寸的颗粒的自组装过程仍然是一个密集的研究领域。此外,由于自组装中的动力学瓶颈而导致的长距离结构的制造是额外的挑战。在这里,我们讨论了从理论和实验的最新进展,特别侧重于最近的模拟研究。

英文摘要:

Colloidal particles grafted with single-stranded DNA (ssDNA) chains can self-assemble into a number of different crystalline structures, where hybridization of the ssDNA chains creates links between colloids stabilizing their structure. Depending on the geometry and the size of the particles, the grafting density of the ssDNA chains, and the length and choice of DNA sequences, a number of different crystalline structures can be fabricated. However, understanding how these factors contribute synergistically to the self-assembly process of DNA-functionalized nano- or micro-sized particles remains an intensive field of research. Moreover, the fabrication of long-range structures due to kinetic bottlenecks in the self-assembly are additional challenges. Here, we discuss the most recent advances from theory and experiment with particular focus put on recent simulation studies.
