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

CTS-9986563B。摘要提出了一种新的生物启发方法来构建空间复杂的量子点异质结构。利用组合多肽进化，将识别选择并结合到特定纳米晶体底物的多肽，例如在溶液中合成的磁性和半导体量子点。这些多肽将引导纳米晶体的空间组织成为量子点异质结构，这些纳米晶体将起到电子“构建块”的作用。半导体-磁体量子点异质结构将在横向和纵向上自组装。目标是利用进化工程的多肽和纳米晶体组装超晶格异质结构，以展示生物系统通常表现出的纳米级分级控制。这些材料在下一代电子器件或混合生物分子系统中具有潜在的用途。

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.
