Nanocellulose-alginate hydrogel for cell encapsulation
TEMPO-oxidized bacterial cellulose (TOBC)-sodium alginate (SA) composites were prepared to improve the properties of hydrogel for cell encapsulation. TOBC fibers were obtained using a TEMPO/NaBr/NaClO system at pH 10 and room temperature.
Double cross-linked interpenetrating polymer network (IPN) hydrogels of sodium alginate and gelatin (SA/G) reinforced with 50 wt % cellulose nanocrystals (CNC) have been prepared via the freeze-drying process. The IPNs were designed to incorporate CNC with carboxyl surface groups as a part of the network contribute to the structural integrity and mechanical stability of the hydrogel.

the high viscosity of sodium alginate, inorganic nanofillers can be well dispersed in the aqueous SA solution. To investigate the e ff orts of inorganic nanoparticles on hydr ogels, PAAM-SA was also
Naturally occurring in seaweed and brown algae, Sodium Alginate (SA) is a linear unbranched polymer consisting of β-D-mannuronic acid (M) and α-L-guluronic acid (G) arranged in a chain sequence of MM-GG-MG (Augst et al., 2006). The presence of carboxyl groups on the surface of SA promotes hydrophilicity and solubility in water.

Nanocellulose was well-dispersed in the PVA-borax (PB) matrix and acted as a cross-linking agent and nanofiller to bridge the 3D network, leading to enhanced mechanical and thermal performance. The effects of particle size, aspect ratio, surface charge and crystallinity on the microstructure and performance were investigated.
To prepare the alginate nanocellulose-based gels, the nanocellulose suspensions (CNC or CNF) were dispersed in a solution of sodium alginate (2 wt %) by sonication for one minute. The concentrations of nanocellulose, described by the numbers in each sample name, are summarized in Table 1 .
Double network hydrogel of sodium alginate/polyacrylamide
1. Introduction. Hydrogels, soft and wet materials, consist of three-dimensional hydrophilic polymeric networks that can adsorb and retain a high amount (up to 90%) of water, saline or physiological solution [1,2], and enabling fast diffusion of foreign molecules into its inner [].In recent years, hydrogels have gained tremendous attention as promising materials in the fields of tissue
An ultra‐stretchable and force‐sensitive hydrogel with surface self‐wrinkling microstructure is demonstrated by in situ synthesizing polyacrylamide (PAAm) and polyaniline (PANI) in closely packed swollen chitosan microspheres, exhibiting ultra‐stretchability (>600%), high sensitivity (0.35 kPa −1) for subtle pressures (<1 kPa), and can detect force in a broad range (10 2 Pa–10 1
