Langmuir Nanoarchitectonics from Basic to Frontier

Abstract

Methodology to combine nanotechnology and these organization processes has been proposed as a novel concept of nanoarchitectonics, which can fabricate functional materials with nanolevel units. As an instant nanoarchitectonics approach, confining systems within a two-dimensional plane to drastically reduce translational motion freedom can be regarded as one of the rational approaches. Supramolecular chemistry and nanofabrication and their related functions at the air-water interface with the concept of nanoarchitectonics would lead to the creation of a novel methodology of Langmuir nanoarchitectonics. In this feature article, we briefly summarize research efforts related to Langmuir nanoarchitectonics including the basics for anomalies in molecular interactions such as highly enhanced molecular recognition capabilities. It is also extended to frontiers including the fabrication of supramolecular receptors and two-dimensional patterns with subnanometer-scale structural regulation, manual control of molecular machines and receptors by hand-motion-like macroscopic actions, and the regulation of cell fates at nanoarchitected arrays of nanocarbon assemblies and at direct liquid interfaces.

Nanoarchitectonics: bottom-up creation of functional materials and systems

“…Because the features of the nanoarchitectonics concept are general and applicable to most materials systems, this concept can be applied to many research targets. In fact, the nanoarchitectonics concept has already been applied in various fields, including materials production [12,13], structural fabrication [14,15], sensing [16,17], catalysis [18], energy [19], environmental [20], devices [21,22], and bio-related [23,24] applications.…”

Materials Nanoarchitectonics as Cell Regulators

“…[5] The nanoarchitectonics concept was originally proposed by Masakazu Aono. [6] It combines nanotechnology with fabrication essences from various research fields such as supramolecular chemistry, materials science, and biological chemistry. In the nanoarchitectonics procedures, functional materials and systems can be architected with various actions and processes including atomic/molecular manipulation, organic synthesis, self-assembly/self-organization and structural regulation upon application of external physical stimuli ( Figure 1).…”

Nanoarchitectonic‐Based Material Platforms for Environmental and Bioprocessing Applications

“…The introduced platforms are roughly classified into (i) membrane platforms and (ii) nanostructured platforms, while nanoarchitectonic strategies are purposefully devised across these platform concepts. In the perspective part, we propose a novel concept for describing interfacial (or Langmuir) nanoarchitectonics [28] as an innovative methodology to achieve energy-efficient control over molecular systems, including molecular machines.…”
