NANOSCALE: Evolutionarily Selected Peptides to Direct the Processing and Self-Assembly of Multicomponent Superlattice Heterostructures

CTS-9986563B。Korgel，德克萨斯大学，奥斯汀摘要提出了一种新的生物启发的方法来构建空间复杂的量子点异质结构。使用组合肽进化，肽将被识别为选择并结合到特定的生物底物，如在溶液中合成的磁性和半导体量子点。肽将指导纳米晶体的空间组织，这将作为电子“积木”，进入量子点异质结构。横向和纵向排列的超导磁体量子点异质结构将被自组装。目标是使用进化工程肽和纳米晶体组装超晶格异质结构，以展示生命系统通常表现出的纳米级分级控制。这些材料的潜在用途是下一代电子器件或混合生物分子系统。

CTS-9986563B. Korgel, University of Texas, AustinAbstractThe development of a new biologically-inspired approach to construct spatially complex quantum dot heterostructures is proposed. Using combinatorial peptide evolution, peptides will be identified that select for and bind to specific nanocrystal substrates, such as magnetic and semiconductor quantum dots synthesized in solution. The peptides will direct the spatial organization of the nanocrystals, which will function as electronic "building blocks," into quantum dot heterostructures. Laterally and vertically organized semiconductor-magnet quantum dot heterostructures will be self-assembled.The goal is to assemble superlattice heterostructures using evolutionarily engineered peptides and nanocrystals to demonstrate the nanometer-scale hierarchical control routinely exhibited by living systems.The potential uses of these materials are in next generation electronic devices, or hybrid biomolecular systems.
