摘要
金、银纳米粒子因其自身优异的理化性能,而被广泛应用在生物检测、医学诊疗、催化、生化传感等领域。随着研究的深入发展,单一组份的功能性粒子已不能满足人们在这些领域的需求。近年来,组成、结构越来越复杂的复合粒子的研究已经成为关注的焦点。我们利用"graft-to"法将两种聚合物修饰到金包银纳米立方体的表面,制备了Ag@Au@PEG/PS的各向异性的两亲性核壳纳米粒子,研究了这类粒子在溶液、液液和液气等介质环境下的组装行为。得到粒子二聚体、粒子链和粒子不同构筑方式形成的单层膜等超粒子结构,并研究和探索了粒子表面修饰和组装体调控的关系与规律等。
Self-assembled nanoparticle superstructures with multi-functionality and biological applications have attracted great interest. In this study, Ag@Au@PEG/PS nanocubes were fabricated, and their self-assembly behaviors in solution, liquid-gas interface or liquid-liquid interface were carefully investigated. The results indicate that the superstructures of dimers, particle chains and complexed membranes could be well constructed from isotropic functional nanocubes.
