Summary: Biodegradable food packaging films (FPFs) made from sustainable biopolymeric materials are increasingly being used in the food industry to reduce pollution and health risks associated with conventional plastic packaging. However, these FPFs often have poorer functional performance compared to traditional plastic films. The incorporation of zinc oxide nanoparticles (ZNPs) into FPFs can improve their properties. This article reviews the design, fabrication, and application of ZNPs-loaded FPFs based on biopolymers, focusing on their impacts on the optical, barrier, mechanical, water sensitivity, and antimicrobial properties of the films. The potential applications of ZNPs-loaded FPFs for fresh food preservation are also discussed.

Summary: Chitosan-bounded copper (chitosan-Cu) was utilized for the green synthesis of novel ferrocenated spiropyrrolidine hybrids. A one-pot three-component 1,3-dipolar cycloaddition reaction using tyrosine, glycine, and isatin derivatives was employed to form spiropyrrolidines from 1-(4-bromophenyl)-ferrocene-prop-2-en-1-one and azomethine ylides. The synthesized spiropyrrolidines showed good antibacterial activity against Gram-positive and Gram-negative bacterial strains.
