Abstract
Linear d-glucans are natural polysaccharides of simple chemical structure. They are comprised of d-glucosyl units linked by a single type of glycosidic bond. Noncovalent interactions within, and between, the d-glucan chains give rise to a broad variety of macromolecular nanostructures that can assemble into crystalline-organized materials of tunable morphology. Structure design and functionalization of d-glucans for diverse material applications largely relies on top-down processing and chemical derivatization of naturally derived starting materials. The top-down approach encounters critical limitations in efficiency, selectivity, and flexibility. Bottom-up approaches of d-glucan synthesis offer different, and often more precise, ways of polymer structure control and provide means of functional diversification widely inaccessible to top-down routes of polysaccharide material processing. Here the natural and engineered enzymes (glycosyltransferases, glycoside hydrolases and phosphorylases, glycosynthases) for d-glucan polymerization are described and the use of applied biocatalysis for the bottom-up assembly of specific d-glucan structures is shown. Advanced material applications of the resulting polymeric products are further shown and their important role in the development of sustainable macromolecular materials in a bio-based circular economy is discussed.

Abstract
Polymer fabrics are versatile materials used in various fields. Surface modification methods for hydrophobic polymer fibers have been developed to endow the materials with water wettability and functionality. Nevertheless, it remains a challenge to freely introduce functional groups to polymer fiber surfaces in a simple manner. Herein, we report the decoration of nonwoven fabric surfaces with azidated cello-oligosaccharide assemblies via molecular self-assembly. Cello-oligosaccharides with a terminal azido group were enzymatically synthesized and allowed to self-assemble in polyolefin, polyester, and vinylon nonwoven fabrics. It was found that the functional oligosaccharides formed bark-like assemblies on the nonwoven fiber surfaces, probably through heterogeneous nucleation. The hydrophilic oligosaccharide assemblies made the hydrophobic nonwoven surfaces water-wettable. Moreover, the azido group at oligosaccharide terminal was available for the post-functionalization of the modified nonwovens. In fact, an antigen was successfully conjugated to the modified nonwovens via the click chemistry. The antigen-conjugated nonwovens were useful for the specific and quantitative detection of a corresponding antibody. Our findings demonstrate the great potential of cello-oligosaccharide assembly for the functionalization of fabrics and other polymeric materials.

Abstract
Inspired by living systems, biomolecules have been employed in vitro as building blocks for creating advanced nanostructured materials. In regard to nucleic acids, peptides, and lipids, their self-assembly pathways and resulting assembled structures are mostly encoded in their molecular structures. On the other hand, outside of its chain length, cellulose, a polysaccharide, lacks structural diversity; therefore, it is challenging to direct this homopolymer to controllably assemble into ordered nanostructures. Nevertheless, the properties of cellulose assemblies are outstanding in terms of their robustness and inertness, and these assemblies are attractive for constructing versatile materials. In this review article, we summarize recent research progress on the self-assembly of cellulose and the applications of assembled cellulose materials, especially for biomedical use. Given that cellulose is the most abundant biopolymer on Earth, gaining control over cellulose assembly represents a promising route for producing green materials with tailor-made nanostructures.

Abstract
HYPOTHESIS The precise control of parallel versus antiparallel molecular arrangements in synthetic assemblies of biorelated molecules is an attractive research focus from both scientific and technological viewpoints. However, little is known about cellulose-based synthetic assemblies. We hypothesized the existence of potential parameters, such as temperature, salt concentration, salt species, and solvent species, for controlling the molecular arrangement in assemblies of alkyl β-cellulosides with different alkyl chain lengths. EXPERIMENTAL The self-assembly of alkyl β-cellulosides was triggered by neutralization-induced water insolubilization. The crystal structures of the cellulose moieties in the assemblies were characterized by attenuated total reflection-Fourier transform infrared absorption spectroscopy and wide-angle X-ray diffraction measurements. The morphologies of the assemblies were also characterized by scanning electron, atomic force, and transmission electron microscopy. FINDINGS The temperature for the self-assembly, the concentration and species of inorganic salt in the self-assembly solution, and the solvent species (namely, the addition of water-miscible organic solvents into the self-assembly solution) strongly affected the molecular arrangement of the assemblies. The observations suggested that hydrophobic effects between the alkyl groups of the alkyl β-cellulosides and/or interactions of the alkyl β-cellulosides with solvent species were potential factors for controlling the molecular arrangement.

Abstract
Two-dimensional (2D) lamellar nanostructures have attracted much interest due to their unique structure and properties. Various fabrication methods have been developed in recent years, including solution self-assembly, exfoliation, and Langmuir monolayer and Langmuir-Blodgett (LB) deposition. In this work, two kinds of facile methods were applied to fabricate lamellar structures of amphiphilic molecules, such as 10,12-pentacosadiynoic acid (PCDA). In method I, the amphiphilic molecules were introduced into aqueous solutions with dimethylformamide (DMF), a solvent miscible with water, through a mass transfer process across a planar liquid/liquid interface; in method II, the DMF solution of the amphiphilic molecules was added directly onto the aqueous solution surface. With the spread and diffusion of DMF, nanosheets with lamellar structures formed in the aqueous solution and at the air/liquid interface, respectively. It is very interesting that the nanosheets obtained through these two methods consist of an even number and odd number of PCDA monolayers, respectively, reflecting different fabrication mechanisms. Method I provides an approach to gently mix organic solutions with aqueous solutions, while method II can be regarded as an extension of the Langmuir monolayer technique, which combines the interfacial assembly with that in solution. These methods have been extended to a series of amphiphilic molecules, and ordered layered structures have been obtained successfully.

Abstract
Molecular self-assembly in solutions is a powerful strategy for fabricating functional architectures. Various bio(macro)molecules have been used as self-assembly components. However, structural polysaccharides, such as cellulose and chitin, have rarely been a research focus for molecular self-assembly, even though their crystalline assemblies potentially have robust physicochemical properties. Herein, we demonstrated the neutralization-induced self-assembly of cellulose oligomers into antibiofouling crystalline nanoribbon networks to produce physically cross-linked hydrogels. The self-assembly proceeded even in versatile complex mixtures, such as serum-containing cell culture media, in a controlled manner for 3D cell culture. The cultured cells grew into cell aggregates (spheroids), which were simply collected through natural filtration due to the mechanically crushable property of the crystalline nanoribbons through water flow by pipetting. We will show the potential of cellulose oligomers for biocompatible, crystalline soft materials.
