“…In recent years, the modification of solid‐state nanopores via polyelectrolyte assembly/adsorption has gained increasing interest . The LbL assembly of polyelectrolytes represents a very simple and versatile chemical method to create functional thin films with nanoscale precision . This functionalization method is based on the alternate deposition of polyanions and polycations on solid surfaces leading to the formation of polyelectrolyte multilayers .…”

Solid‐state nanopores are fascinating objects that enable the development of specific and efficient chemical and biological sensors, as well as the investigation of the physicochemical principles ruling the behavior of biological channels. The great variety of biological nanopores that nature provides regulates not only the most critical processes in the human body, including neuronal communication and sensory perception, but also the most important bioenergetic process on earth: photosynthesis. This makes them an exhaustless source of inspiration toward the development of more efficient, selective, and sophisticated nanopore‐based nanofluidic devices. The key point responsible for the vibrant and exciting advance of solid nanopore research in the last decade has been the simultaneous combination of advanced fabrication nanotechnologies to tailor the size, geometry, and application of novel and creative approaches to confer the nanopore surface specific functionalities and responsiveness. Here, the state of the art is described in the following critical areas: i) theory, ii) nanofabrication techniques, iii) (bio)chemical functionalization, iv) construction of nanofluidic actuators, v) nanopore (bio)sensors, and vi) commercial aspects. The plethora of potential applications once envisioned for solid‐state nanochannels is progressively and quickly materializing into new technologies that hold promise to revolutionize the everyday life.

“…Azzaroni, Rafti, and co‐workers demonstrated the hierarchic integration of conductive polymers with MOF structures using LbL assembly as a nanoarchitectonics essence ( Figure ). [ 76 ] Fabrication of these hierarchical nanostructures started from synthesis of two kinds of colloidal assemblies: anionic polyaniline (PANI)/poly(styrene sulfonate) (PSS) colloidal particles and zeolitic imidazolate framework‐8 (ZIF‐8) colloidal particles modified with cationic poly(allylamine hydrochloride) (PAH). These electrically opposite colloidal substances were then assembled into nanoarchitected thin films by the LbL assembly.…”

Along with the progresses of material syntheses, the importance of structural regulation is realized to rationally improve the efficiencies and specificities in target functions. Small science is necessary for advanced material systems. A novel concept, nanoarchitectonics, to combine nanotechnology with the other scientific disciplines to synthesize a functional material system with contributions of small objects, nano‐units, is recently proposed. Based on facts and knowledge in nanoscale objects explored by nanotechnology, functional material systems are constructed using nano‐units with the aid of the other research fields, such as organic chemistry, supramolecular chemistry, materials science, and biology. The introduction of nanoarchitectonics essences to material construction can produce unusual functional systems, such as brain‐like information processing based on atomic‐level reactions, diffusions, and aggregations. Probe‐tip‐mediated organic reactions are also possible with precise site selectivity. The coupling of equilibrium self‐assemblies and non‐equilibrium fabrication processes results in variously structured and hierarchical functional structures even from simple 0D nano‐units such as fullerenes. Especially, interfacial nanoarchitectonics directly bridge nanoscopic functions and macroscopic actions, including facile contact with nanostructures and living cells. This review article overviews nanoarchitectonics from origin to future, from atoms to materials, and from small science to big technology.

Because of their outstanding structural, chemical, and functional diversity, metal‐organic frameworks (MOFs) have brought about worldwide interest over the last 2 decades, which have been utilized in a wide range of applications in the fields of gas separation, storage, catalysis, and drug delivery. However, among these applications, MOFs are almost used in the form of powder. Due to their fragility and difficulty in preparing large‐area thin film materials, the study of MOF films and their electronic properties is a challenging problem in the research of MOFs. Owing to the low‐energy charge transport mode, most MOF films are essentially insulating, which largely limits their applications in fields where electronic charge transport takes place, such as electronics or electrochemistry. So, the introduction of conductivity into the MOF films opens new avenues for their applications in electrochemical sensing, supercapacitors, batteries, electrocatalysis, and electronic devices and makes the research on and with MOF films very active. Herein, the latest progress of conductive MOF films, including the preparation of MOF films, the design and adjustment strategies for constructing intrinsic and doping conductive MOF films, and their applications are reviewed. In addition, the numerous challenges of conductive MOF films are also elaborated.
