In this study, we successfully synthesized well-defined polygonal gold microplates for the first time in an aqueous phase using hydroxyethylcellulose (HEC) in the presence of hydrogen peroxide (HO). HEC played a pivotal role during the synthesis, acting not only as a biotemplate but also as an in situ reduction site for the nucleation and growth of gold (Au) microplates. HO played a crucial role in accelerating the growth of Au microplates from the Au nucleus. This methodology is ecofriendly and easy to operate and has potential applications in various fields, such as electronics, photonics, and biotechnology.
在本研究中，我们首次在水相中使用羟乙基纤维素（HEC），在过氧化氢（HO）存在的情况下成功合成了形状规整的多边形金微板。HEC在合成过程中发挥了关键作用，不仅作为生物模板，还作为金（Au）微板成核和生长的原位还原位点。HO在加速金微板从金核生长的过程中起着至关重要的作用。这种方法环保且易于操作，在电子、光子学和生物技术等各个领域具有潜在应用。
