Characterization of prepared corn starch-based hydrogel membranes

Area of Science:

• Biomaterials Science
• Polymer Chemistry
• Materials Engineering

Background:

• Hydrogel membranes are crucial in various biomedical and industrial applications.
• Developing sustainable and biocompatible hydrogels is an ongoing research focus.
• Polyvinyl alcohol (PVA) and cornstarch (CS) are abundant biopolymers with potential for hydrogel formation.

Purpose of the Study:

• To design and develop novel hydrogel membranes using polyvinyl alcohol and heat-treated cornstarch.
• To characterize the degradation, mechanical properties, swelling behavior, and cytocompatibility of the developed hydrogel membranes.

Main Methods:

• Hydrogel membranes were synthesized by crosslinking polyvinyl alcohol with heat-treated cornstarch and cornstarch suspensions.
• Degradation studies were performed using α-amylase.
• Mechanical properties were assessed using tensile tests.
• Swelling behavior was evaluated.
• Cytocompatibility was determined using methyl tetrazolium assays with L929 cell lines and mice splenocytes.

Main Results:

• The developed hydrogel membranes demonstrated sufficient mechanical strength.
• The membranes exhibited adequate water holding capacity.
• Degradation studies indicated susceptibility to α-amylase.
• Methyl tetrazolium assays confirmed the cytocompatibility of the membranes with L929 fibroblast cells and mice splenocytes.

Conclusions:

• Novel hydrogel membranes were successfully prepared using polyvinyl alcohol and cornstarch.
• The hydrogel membranes possess desirable mechanical and swelling properties.
• The developed materials are biocompatible, indicating potential for further research and application.
