Abstract
Polyurethane is a widely used material because of its excellent properties. Cellulose is a renewable, biocompatible, and biodegradable natural polymer that also has the advantages of a low density, high porosity, and large specific surface area. There are three main types of common nanocellulose: nanocellulose fibers, cellulose nanocrystals, and bacterial nanocellulose. Composites prepared with nanocellulose and polyurethane materials have good mechanical properties and good biocompatibility and can be applied in sensors, 3D printing, self-repairing materials, electromagnetic shielding, and many other areas. This paper details the preparation processes of different nanocelluloses and the application areas of composites, and points to the future development of nanocellulose polyurethane composites.

Abstract
Nanocellulose hydrogels are a crucial category of soft biomaterials with versatile applications in tissue engineering, artificial extracellular matrices, and drug-delivery systems. In the present work, a simple and novel method, involving the self-assembly of cellulose nanocrystals (CNCs) induced by tannic acid (TA), was developed to construct a stable hydrogel (SH-CNC/TA) with oriented porous network structures. The gelation process is driven by the H-bonding interaction between the hydroxyl groups of CNCs and the catechol groups of TA, as substantiated by the atoms in molecules topology analysis and FTIR spectra. Interestingly, the assembled hydrogels exhibited a tunable hierarchical porous structure and mechanical moduli by varying the mass ratio of CNCs to TA. Furthermore, these hydrogels also demonstrate rapid self-healing ability due to the dynamic nature of the H-bond. Additionally, the structural stability of the SH-CNC/TA hydrogel could be further enhanced and adjusted by introducing coordination bonding between metal cations and TA. This H-bonding driven self-assembly method may promote the development of smart cellulose hydrogels with unique microstructures and properties for biomedical and other applications.

Abstract
Cellulose nanocrystal and gold nanoparticles are assembled, in a unique way, to yield a novel modular glyconanomaterial whose surface is then easily engineered with one or two different headgroups, by exploiting a robust click chemistry route. We demonstrate the potential of this approach by conjugating monosaccharide headgroups to the glyconanomaterial and show that the sugars retain their binding capability to C-type lectin receptors, as also directly visualized by cryo-TEM.

Abstract
The superiority of self-healing hydrogel systems with dynamic covalent chemistry is the ability to establish the gel network structure despite changes in ambient conditions such as pH, temperature, and ion concentrations. The Schiff base reaction, which occurs through aldehyde and amine groups, allows dynamic covalent bonds at physiological pH and temperature. In this study, gelation kinetics between glycerol multi-aldehyde (GMA) and water-soluble form of chitosan, carboxymethyl chitosan (CMCS), has been investigated, and the self-healing ability has been evaluated in detail. Macroscopic and electron microscope-based visual inspection and rheological tests showed that the hydrogels exhibit the highest self-healing capacity at 3-4 % CMCS and 0.5-1 % GMA concentrations. Hydrogel samples were subjected to alternating high and low strains to deteriorate and rebuild the elastic network structure. The results showed that hydrogels could restore their physical integrity after applying 200 % strains. In addition, direct cell encapsulation and double staining tests showed that the samples do not possess any acute cytotoxicity on mammalian cells; hence, hydrogels could potentially be used in tissue engineering applications for soft tissues.
