Marigold flower like supra structure is fabricated by growth reaction of gold nanorod incubated with methionine with two binding site, which selectively interacts with intermediate Au⁺ and Au(111) facets during nucleation and growth stage and favors the assembly and merging of nanoparticles. This observation enlightens the role of biomolecules or small molecules behind growth of novel nano-architectures.

来自蛋氨酸介导的带正电金纳米棒生长的万寿菊样结构

万寿菊花状结构是通过金纳米棒与蛋氨酸孵育的生长反应制成的，具有两个结合位点，在成核和生长阶段选择性地与中间Au ⁺和Au(111)面相互作用，有利于纳米颗粒的组装和合并。这一观察揭示了生物分子或小分子在新型纳米结构生长背后的作用。
