Nanoarchitectonics from Molecular Units to Living‐Creature‐Like Motifs

Abstract

Important points for the fabrication of functional materials are the creation of nanoscale/molecular-scale units and architecting them into functional materials and systems. Recently, a new conceptual paradigm, nanoarchitectonics, has been proposed to combine nanotechnology and other methodologies including supramolecular chemistry, self-assembly and self-organization to satisfy major features of nanoscience and promote the creation of functional materials and systems. In this account article, our recent research results in materials development based on the nanoarchitectonics concept are summarized in two stories, (i) nanoarchitectonics from fullerenes as the simplest nano-units and (ii) dimension-dependent nanoarchitectonics from various structural units. The former demonstrates creativity of the nanoarchitectonics concept only with simple construction stuffs on materials fabrications, and a wide range of material applicability for the nanoarchitectonics strategy is realized in the latter ones.

Self-assembly as a key player for materials nanoarchitectonics

“…An interesting example of bio-like shape-shifting selfassembly is supramolecular differentiation, a novel concept proposed by Bairi et al (Figure 17) [256,257]. This phenomenon was discovered through two-step process interfacial self-assembly (two-phase system of iso-propyl alcohol and toluene) of mixed fullerene derivatives, pentakis(phenyl)fullerene and pentakis-(4-dodecylphenyl)fullerene, followed by sonication mixing after a certain period.…”

Nanoarchitectonics beyond Self‐Assembly: Challenges to Create Bio‐Like Hierarchic Organization

“…In general, regulation of function through control of materials organization can be found in systems ranging from atomic-level assemblies right up to the scale of biological entities. [128] At ypical example of nanoarchitectonics can be found in an atomic-level structural organization, conversion from ions to atoms,their diffusion, and precipitation between electrodes with nano-size gap to regenerate bio-like functions, short-term plasticity and long term potentiation, as artificial synapses,ashas been demonstrated by Aono and co-workers (Figure 30 A). [129] On the other hand, Fakhrullin and coworkers demonstrated hybridization of nanomaterials with biological entities (i.e., cells) to create cyborg cells through the decoration of bacteria with silver nanoparticles and their delivery to C. elegans microworms (Figure 30 B).…”

Nanoarchitektonik als ein Ansatz zur Erzeugung bioähnlicher hierarchischer Organisate

“…Im Allgemeinen ist die Regulierung von Funktion durch eine Kontrolle der Materialorganisation in Systemen zu finden, die von Assemblierungen auf atomarer Ebene bis hin zum Maßstab biologischer Einheiten reichen. [128] Ty pische Beispiele fürd ie Nanoarchitektonik sind die Strukturorganisation auf atomarer Ebene,d ie Umwandlung von Ionen in Atome,d eren Diffusion und die Niederschlagbildung zwischen Elektroden mit nanogroßen Abständen zur Regenerierung bioähnlicher Funktionen, Kurzzeitplastizitätu nd Langzeitpotenzierung,a ls künstliche Synapsen, was von Aono und Mitarbeitern veranschaulicht wurde (Abbildung 30 A). [129] Fakhrullin und Mitarbeiter wiederum de-monstrierten die Hybridisierung von Nanomaterialien mit biologischen Einheiten (d. h. Zellen) zur Darstellung von Cyborg-Zellen durch die Ausstattung von Bakterien mit Silbernanopartikeln und deren Tr ansport zu C. elegans-Mikrowürmern (Abbildung 30 B).…”
