In this study, we formulated an oil-in-water nanoemulsion of seed oil in the presence of methanolic extract using a delivery system based on sodium alginate. The control nanoemulsion was prepared without plant extract and the nanoemulsion loaded with extract was further characterized based on their size, polydispersity index, morphology, and stability. The nanoemulsion showed an average droplet size of about 192 nm, with a polydisperse droplet size with a spherical shape and the zeta potential of -15.0 mV and -18.4 mV. In contrast to the control nanoemulsion, the drug release rate of the nanoemulsion formulation was found to be significant ( <0.05). Antibacterial activity was assessed against a variety of pathogenic bacterial and fungal strains and the formulated nanoemulsion exhibited significantly higher potency against them in comparison to extract alone. The results revealed thermodynamically stable nanoemulsion which could be used for various therapeutic applications.

Objective: The difficulty of establishing slow release at intestinal infection sites, weak antibacterial effects, as well as the limited broad use of florfenicol oral formulations are the main targets of the current study. Novel hydrogels derived from sodium alginate were developed using a complexation form for florfenicol delivery to achieve slow release at the site of intestinal infection and enhance its antibacterial activity against .
Methods: The optimal formulation, physicochemical properties, stability, pH-responsive performance, antibacterial activity, and in vitro biosafety of the florfenicol hydrogels have been studied systematically.
Investigation of Response Characteristics and Reaction Mechanisms in Nanonickel Doped Sodium Alginate/Graphene Oxide Artificial Muscles.

To address the shortcomings of traditional actuators, such as large size, high energy consumption, and slow response, this study developed a conductive and responsive artificial muscle, exploring the operational principles and performance enhancement techniques for artificial muscles made from sodium alginate and graphene oxide. Initially, the research outlined a preparation methodology using sodium alginate, graphene oxide, and nanonickel as primary materials. Subsequent adjustments in the nanonickel content optimized critical performance metrics, including output force, lifespan, and deflection displacement.

Soybean protein isolate (SPI) exhibits limited functional properties in processing applications due to environmental stressors such as pH, salt ion, and temperature. The present study was devoted to exploring the non-covalent assembly of SPI with chitosan (CS), glucan (GL) and sodium alginate (SA) under different pH conditions. At a fixed mixing ratio (1:1), the phase behavior, protein solubility, and surface hydrophobicity (H) of the resulting protein-polysaccharide complexes (PPCs) exhibited great differences due to the diversity of polysaccharide charge density and structure.
