The current research is aimed at investigating the relationship between the formulation components and conditions in the case of a binary drug delivery system, where antidiabetic drugs are co-formulated into polymeric micelles embedded in sodium alginate. Compared to chemical modifications of polymers with alginate, our development provides a simpler and scalable formulation process. Our results prove that a multi-level factorial design-based approach can ensure the development of a value-added polymeric micelle formulation with an average micelle size of 123.6 ± 3.1 nm and a monodisperse size distribution, showing a polydispersity index value of 0.215 ± 0.021. The proper nanoparticles were co-formulated with sodium alginate as a biologically decomposing and safe-to-administer biopolymer. The Box-Behnken factorial design ensured proper design space development, where the optimal sodium alginate bead formulation had a uniform, extended-release drug release mechanism similar to commercially available tablet preparations. The main conclusion is that the rapid-burst-like drug release can be hindered via the embedment of nanocarriers into biopolymeric matrices. The thermally stable formulation also holds the benefit of uniform active substance distribution after freeze-drying.

This study presents a straightforward and rapid method for preparing graphene aerogel by integrating a sodium alginate (SA)-metal ion crosslinking system, a bubble template, and an osmotic dehydration process. Graphene oxide (GO) nanosheets were dispersed into the solution crosslinked by SA and metal ions, leading to rapid gelation of GO under ambient conditions. To minimize structural damage to the porous network caused by water molecules during the drying process, an osmotic dehydration technique was employed as an auxiliary drying method.

Herein, we present a simple and novel method to prepare soybean protein isolate (SPI)-based hydrogels with good mechanical characteristics. First, SPI/DSA hydrogels were prepared using SPI and different M/G ratios (1:2, 1:1, and 2:1) of dialdehyde sodium alginate (DSA). Then, the hydrogels were immersed in CaCl2 solution to form SPI/DSA@Ca double network hydrogels.

At present, flexible sensors are a hot spot in research and experimental development, but the research on flexible sensors that can be used for human motion monitoring still needs to be deepened. In this work, the green material cellulose acetate (CA) was used as the matrix material, the film was made by electrospinning, crushed by a cell grinder and sodium alginate (SA) was added to promote the uniform dispersion of nanofibers in water, and then methyltrimethoxysilane (MTMS) and MXene nanosheet dispersion were added to make it hydrophobic and good conductivity, and the aerogel precursor solution was prepared, and then the CA/SA/MTMS/MXene aerogel with directional holes was prepared by directional freeze-drying. As a flexible sensor material, it can be used for human wear, monitoring the electrical signals generated by the movement of human joints and other parts, and can still maintain a current of about 0.

Bioprotective LAB3 cells that produce bacteriocin-like substances were entrapped in 4% (w/w) sodium alginate matrices, either with or without 10% (w/w) sodium caseinate. The effects of bead formulation-alginate alone or combined with caseinate, with or without the addition of 20% (w/w) MRS broth or M17 broth-on the culturability of LAB3 cells within the beads and their anti activity were assessed over 12 days of storage at 30 °C in closed bottles. Calcium-alginate-caseinate beads supplemented with MRS broth proved most effective in preserving both culturability and anti- activity.

This study focuses on the issues of poor fluidity, low penetration into residual coal, and suboptimal inhibition of coal spontaneous combustion associated with traditional coal mine gel fire retardants. The permeability and flow characteristics of a sodium alginate-based composite thermosensitive hydrogel, as well as its fire prevention and extinguishment performance, were investigated. The findings suggest that the thermosensitive hydrogel behaves as a pseudoplastic fluid at 40 °C and a yield-pseudoplastic fluid at 65 °C, exhibiting shear-thinning behavior with increasing shear rate.
