The Swelling Properties of Chitosan/Agar Chemically Cross-linkedHydrogel Beads

This study describes the synthesis of biopolymer-based hydrogel beads through the chemicalcrosslinking of chitosan and agar. A gel solution was prepared by dissolving agar in an aqueouschitosan solution, followed by dispersion into an oily phase using a syringe pump. The resultinghydrogel beads were then chemically crosslinked by soaking them in a solution containingcrosslinkers, followed by drying. The properties of the beads were characterized using FTIR, SEM,and optical imaging techniques, revealing the formation of imine bonding and a porous structure withspherical morphology. The beads exhibited a narrow size distribution and demonstrated controlledswelling behavior in response to various parameters such as soaking time, crosslinker concentration.
