Abstract

To achieve chiral amplification, life uses small chiral molecules as building blocks to construct hierarchical chiral architectures that can realize advanced physiological functions. Inspired by the chiral amplification strategy of nature, we herein demonstrate that the chiral assembly of chiral gold nanorods (GNRs) leads to enhanced optical asymmetry factors (g-factors), up to 0.24. The assembly of chiral GNRs, dictated by structural self-matching, leads to g-factors with over 100-fold higher values than those of individual chiral GNRs, as confirmed by numerical simulations. Moreover, the efficient optical asymmetry of chiral GNR assemblies enables their application as highly sensitive sensors of adenosine triphosphate (ATP detection limit of 1.0 μM), with selectivity against adenosine diphosphate and adenosine monophosphate.

手性金纳米粒子的自匹配组装实现了高度光学不对称和灵敏的三磷酸腺苷检测。

为了实现手性放大，生命利用小手性分子作为构件来构建分层手性结构，从而实现先进的生理功能。受自然界手性放大策略的启发，我们在本文中证明，手性金纳米棒（GNRs）的手性组装可增强光学不对称系数（g-factors），最高可达 0.24。手性 GNR 的组装由结构自匹配决定，其 g 因子值比单个手性 GNR 的 g 因子值高出 100 多倍，这已得到数值模拟的证实。此外，手性 GNR 组件的高效光学不对称性使其能够用作高灵敏度的三磷酸腺苷传感器（ATP 检测限为 1.0 μM），对二磷酸腺苷和单磷酸腺苷具有选择性。
