Enhancing biodegradable smart food packaging: Fungal-synthesized nanoparticles for stabilizing biopolymers.

The increasing global concern over environmental plastic waste has propelled the progress of biodegradable supplies for food packaging. Biopolymer-based packaging is undergoing modifications to enhance its mechanical properties, aligning with the requirements of smart food packaging. Polymer nanocomposites, incorporating reinforcements such as fibers, platelets, and nanoparticles, demonstrate significantly improved mechanical, thermal, optical, and physicochemical characteristics.

Synthesis of a novel magnetic starch-alginic acid-based biomaterial for drug delivery.

The magnetic composite hydrogel was fabricated by the graft copolymerization of itaconic acid (IA) onto starch and Alginic acid in the presence graphene sheets (Gr) and FeO nanoparticles (FeO@Gr-IA/St-Alg) for Guaifenesin (GFN) delivery and wound healing. The FeO@Gr-IA/St-Alg biomaterial is a hydrogel network endowed the material with magnetic property. In addition, GFN not only achieved effectively bound to the magnetic hydrogel, but also released in a controlled manner.
