“…For example, minimizing the number of LbL components and reducing the presence of a cationic component results in greatly reduced cytoxicity. [27][28][29][30][31][32] Various species (drugs, genes, or nanoparticles) can be encapsulated within LbL microcapsules for further delivery by employing two different strategies: "pre-loading" and "postloading". In the post-loading approach, prefabricated capsules are loaded with the molecules of interest by changing the permeability of the capsule shell by variation of pH or ionic strength.…”

“…Tsukruk and co-workers reported cell surface modification through LbL assembly of hydrogen-bonded shells with inclusion of tannic acid as a critical component. 384 The latter component leads to high viability of the wrapped cells over extended periods of time. Cell encapsulation using nontoxic, nonionic, and biocompatible components, such as poly(N-vinylpyrrolidone) and tannic acid, leads to cells with higher diffusion and outstanding survivabilities, which reach 79%, in contrast to only 20% viability achieved with ionically paired coatings.…”

Materials fabrication with nanoscale structural precision based on bottom-up-type self-assembly has become more important in various current disciplines in chemistry including materials chemistry, organic chemistry, physical chemistry, analytical chemistry, biochemistry, colloid and surface chemistry, and supramolecular chemistry. Although the design of new materials based on nanoscale self-assembly is anticipated as a key concept, preparing complete three-dimensional structures at nanoscale precision remains a difficult target using current technologies. Rather, dimension-reduced approaches such as layering of two-dimensional nanostructures into precisely controlled lamellar nanomaterials are currently achievable. In particular, layer-by-layer (LbL) assembly is known as a highly versatile method for fabrication of controlled layered structures from various kinds of component materials using very simple, inexpensive, and rapid procedures. Therefore, fabrication of multilayer films through the LbL deposition process has attracted growing interest from various research communities. The high versatility and flexibility of LbL assembly is continuously creating new concepts, new materials, new procedures, and new applications. In this highlight review, we focus on nanoarchitectonics by LbL assembly. After an initial introduction on the invention and a brief history of the LbL assembly technique, innovations and the evolution of the technique are described based mainly on recent examples, which are categorized into two sections: (i) developments in methodology (technical, material, and phenomenological aspects with expansion of concept) and (ii) progress in applications (physical, chemical/biochemical, and biomedical applications).

Layer-by-layer encapsulation of living biological cells and other microorganisms via sequential adsorption of oppositely charged functional nanoscale components is a promising instrument for engineering cells with enhanced properties and artificial microorganisms. Such nanoarchitectural shells assembled in mild aqueous conditions provide cells with additional abilities, widening their functionality and applications in artificial spore formation, whole-cell biosensors, and fabrication of three-dimensional multicellular clusters.
