“…This strategy could be one of the best methods for creating high-quality thin-film structures. 72,73 For example, two-dimensional crystals of colloidal particles are expected to have functionalities such as optical applications, electrochemical applications, and conjugation with biological materials. However, due to the compatibility of the substrate on which the colloidal crystals are placed, the fabrication conditions are difficult to generalize.…”

Considering the creation of functional materials based on nanoscience, an emerging concept of nanoarchitectonics has been proposed to combine nanotechnology with other material-related fields. Nanoarchitectonics aims to establish universal methodologies to architect functional materials using nanounits of atoms, molecules, and nanomaterials. The ultimate goal of nanoarchitectonics is to construct high-performance functional materials, as seen for those in biological systems. Functional molecules in biological systems are rationally integrated, mostly on the basis of various membrane structures. With this in mind, this review discusses materials nanoarchitectonics for two-dimensional films. As major methods, the Langmuir−Blodgett (LB) method and the layer-by-layer (LbL) assembly are first focused. The standard LB method for various materials and technical extensions of the LB method are initially discussed, and then the LbL assembly with certain advances is described. After that, some examples of other advanced twodimensional techniques for materials creation are presented. Although standard methodologies have long histories (more than 100 years for LB and 30 years for LbL), their developments are still active using out of common sense conditions and introducing emerging nanomaterials. Especially, this paper demonstrates that out-of-box thinking will lead to the development of new thin film nanoarchitectonics.

“…To overcome the limitations of complex synthetic procedures as well as inhomogeneous distribution, development of nanoarchitectonics , ( in situ crystal growth of ZIF-8) within a hydrogel can be a smart solution to this problem. Nanoarchitectonics are functional materials architected using nanoscale units by following the principles of nanotechnology.…”

Metal–organic frameworks (MOFs) have dramatically changed the fundamentals of drug delivery, catalysis, and gas storage as a result of their porous geometry, controlled architecture, and ease of postsynthetic modification. However, the biomedical applications of MOFs still remain a less explored area due to the constraints associated with handling, utilizing, and site-specific delivery. The major drawbacks associated with the synthesis of nano-MOFs are related to the lack of control over particle size and inhomogeneous dispersion during doping. Therefore, a smart strategy for the in situ growth of a nano-metal–organic framework (nMOF) has been devised to incorporate it into a biocompatible polyacrylamide/starch hydrogel (PSH) composite for therapeutic applications. In this study, the post-treatment of zinc metal ion cross-linked PSH with the ligand solution generated the nZIF-8@PAM/starch composites (nZIF-8, nano-zeolitic imidazolate framework-8). The ZIF-8 nanocrystals thus formed have been found to be evenly dispersed throughout the composites. This newly designed nanoarchitectonics of an MOF hydrogel was found to be self-adhesive, which also exhibited improved mechanical strength, a viscoelastic nature, and a pH-responsive behavior. Taking advantage of these properties, it has been utilized as a sustained-release drug delivery platform for a potential photosensitizer drug (Rose Bengal). The drug was initially diffused into the in situ hydrogel, and then the entire scaffold was analyzed for its potential in photodynamic therapy against bacterial strains such as E. coli and B. megaterium. The Rose Bengal loaded nano-MOF hydrogel composite exhibited remarkable IC50 values within the range of 7.37 ± 0.04 and 0.51 ± 0.05 μg/mL for E. coli and B. megaterium. Further, reactive oxygen species (ROS) directed antimicrobial potential was validated using a fluorescence-based assay. This smart in situ nanoarchitectonics hydrogel platform can also serve as a potential biomaterial for topical treatment including wound healing, lesions, and melanoma.

“…Nanoarchitectonics [ 44 – 45 ], which can be considered a post-nanotechnology concept [ 46 ], can play this role. Just as Richard Feynman proposed nanotechnology in the 20th century [ 47 – 48 ], nanoarchitectonics was proposed by Masakazu Aono in the early 21st century [ 49 – 50 ]. Nanoarchitectonics is a methodology for creating functional materials systems using nanoscale units such as atoms, molecules, and nanomaterials.…”

The development of nanotechnology has provided an opportunity to integrate a wide range of phenomena and disciplines from the atomic scale, the molecular scale, and the nanoscale into materials. Nanoarchitectonics as a post-nanotechnology concept is a methodology for developing functional material systems using units such as atoms, molecules, and nanomaterials. Especially, molecular nanoarchitectonics has been strongly promoted recently by incorporating nanotechnological methods into organic synthesis. Examples of research that have attracted attention include the direct observation of organic synthesis processes at the molecular level with high resolution, and the control of organic syntheses with probe microscope tips. These can also be considered as starting points for nanoarchitectonics. In this review, these examples of molecular nanoarchitectonics are introduced, and future prospects of nanoarchitectonics are discussed. The fusion of basic science and the application of practical functional materials will complete materials chemistry for everything.
