Background And Aim: Cell encapsulation using biodegradable material has promising results for tissue engineering. Since pressure is an effective factor on stem cell behaviour and various concentrations of alginate create different pressures on the cells, therefore our goal was to evaluate the mechanical effect of 1/2% (w/v) and 1/8% (w/v) alginate containing high guluronic acid on viability and osteogenic capacity of HUCWJ cells.
Methods: Cell viability was evaluated by MTT assay after 1, 7 and 14 days. Alkaline phosphatase activity was evaluated by alkaline phosphatase assay kit after 14 and 21 days. Alizarin red S staining was performed for calcium deposition among histological section.
Results: MTT assay showed significant difference in the mean of viability rates between groups in day 14 (p < 0.05). Alizarin red S staining was higher in the group 1.8%. In addition, there was statistically significant higher ALP activity in the group 1.8% compared to the group 1.2%.

The probiotic encapsulation system has the potential to enhance the prebiotic effects of probiotics. However, challenges arise from the release behavior of this system in vivo and the large size of hydrogel beads. This study aims to address the issues related to the size of previous hydrogel beads and assess the colon-targeted delivery of probiotic polysaccharides composite hydrogel beads (PPHB).

Ionic conductive hydrogels (ICHs) are emerging as key materials for advanced human-machine interactions and health monitoring systems due to their unique combination of flexibility, biocompatibility, and electrical conductivity. However, a major challenge remains in developing ICHs that simultaneously exhibit high ionic conductivity, self-healing, and strong adhesion, particularly under extreme low-temperature conditions. In this study, a novel ICH composed of sulfobetaine methacrylate, methacrylic acid, TEMPO-oxidized cellulose nanofibers, sodium alginate, and lithium chloride is presented.

Oleogels with solid-like properties can serve as substitutes for fats, thereby avoiding the consumption of high levels of saturated fatty acids. In this study, we developed a protein-polysaccharide composite network oleogel using whey protein isolate (WPI) and sodium alginate (SA) through an emulsion-templated method. Analysis with Fourier Transform Infrared (FTIR) spectroscopy confirmed the presence of hydrogen bonds and van der Waals forces between WPI and SA, which bolstered the oleogel's structure.

In this study, we demonstrate MXene (TiCT)-based coin-cell asymmetric supercapacitor (coin-cell ASC) exhibiting high energy density and high power density along with good capacitance. We synthesized mesoporous carbon (MC) by annealing alginic acid at varying temperatures (900 °C, 1000 °C and 1100 °C). Among the prepared samples, MC-1000 exhibited a highly porous structure and a higher surface area.

Hydrogel-based patches have demonstrated their values in diabetic wounds repair, particularly those intelligent dressings with continuous repair promoting and monitoring capabilities. Here, we propose a type of dual physiological responsive structural color particles for wound repair. The particles are composed of a hyaluronic acid methacryloyl (HAMA)-sodium alginate (Alg) inverse opal scaffold, filled with oxidized dextran (ODex)/quaternized chitosan (QCS) hydrogel.
