Small Science: 纳米组装学的变革和演化——对话日本国立物质材料研究所有贺克彦(Katsuhiko Ariga)教授

WILEY开放获取(OA)旗舰期刊Small Science近日发表了日本国立物质材料研究所有贺克彦(Katsuhiko Ariga)教授的关于纳米组装学(nanoarchitectonics)的展望论文。在这篇讲述纳米组装学“前世今生”的文章中,Ariga教授系统地总结了纳米组装学的发展和现状,并且展望了如何从小单元最终组装实现能够模拟数十亿年进化的自然功能的人工生物体。在文后彩蛋中,于教授本人的一句话“快问快答”可以让我们看到科研大咖的另一面。

“纳米组装学”(nanoarchitectonics)这个概念最早是在2000年由时任日本理化学研究所首席科学家的Masakazu Aono 教授(现在日本国立物质材料研究所工作)提出。Aono 教授认为,纳米技术不仅仅是微米技术在尺度上的简单延伸,因此有必要创造一个新的名词来反映研究范式上的变化。作为材料科学和技术在纳米尺度的研究范式,纳米组装学根据纳米技术研究对象的本体和特性,借助有机化学、超分子化学、材料科学和生物学等其他研究领域的知识,使用纳米单元构建功能化的材料系统。所以纳米组装方法通常被认为是旨在将纳米尺度的科学与材料技术联系起来,从“小”科学到“大”技术。

从2003 年第一次出现在论文里,纳米组装学的概念已经扩展到众多研究领域,并且在有机合成、聚合物化学和材料科学方面取得了巨大成就,在器件制造、能源和环境科学、生物和医学等领域得到广泛应用。其中,日本国立物质材料研究所有贺克彦(Katsuhiko Ariga)教授做出了突出贡献,他的工作涉及LbL/Langmuir-Blodgett 膜等自组装技术、纳米结构组装以及界面化学等多个方面。随着材料合成的发展,结构调控的重要性也日益凸显。如何合理地提高目标功能的效率和特异性,并将纳米建筑技术的本质引入材料构造会产生不同寻常的功能系统成为广大研究人员关注的重点:例如基于原子级反应的扩散和聚集构建类大脑的信息处理系统;探针介导有机反应带来的精确位点选择性;甚至简单通过零维纳米单元平衡态自组装与非平衡态过程的耦合就能带来结构化和层次化的功能结构。特别是,界面纳米组装学直接桥接了纳米功能和宏观行为,包括纳米结构和活细胞的便捷接触。有贺克彦教授在Small Science发表的这篇题为《Nanoarchitectonics Revolution and Evolution: From Small Science to Big Technology》的文章里概述了从起源到未来、从原子到材料、从小科学到大技术的纳米组装学。相关论文发表在 Small Science (DOI: 10.1002/smsc.202000032)
