Abstract
AbstractThe radical proliferation of pathogenic bacteria and their infections causes significant issues for human health and the environment. Today, biopolymers are used to produce different nanoparticles. In the present investigation, the fabricated chitosan/agar-silver nanoparticles (Cht/Ar-AgNPs)-coated papers were tested for antibacterial applications. Agar was used as a reducing agent for the synthesis of AgNPs. Synthesized Ar-AgNPs were examined through optical, phase crystallinity and topological analysis. Cht and Ar-AgNPs solution was mixed with various ratios of 9:1, 8:2, 7:3, 6:4, and 5:5 by weight. In addition to that, the conformity of Cht/Ar-AgNPs-coated papers was characterized by structural, spectral, and morphological analysis. However, Cht/Ar-AgNPs-coated papers were subjected to antibacterial properties. The ratio of (6:4) Cht/Ar-AgNPs-coated paper showed excellent antibacterial agent, and it can be used as extending the food product shelf life.
Highlights
Biopolymers are considered an ideal candidate for nanotechnology’s recent advent due to the biocompatibility, reducing/capping ability, and different physicochemical properties, especially nontoxicity to an environment
Biopolymer films and coatings are used for many applications: it serves as the best food packaging material, minimizes food deterioration, extends food life by serving as solute and gas barriers, and acts as various additives [1,2,3,4,5]
During AgNPs synthesis, in the reduction process, the colorless agar with AgNO3 mixture changed to brown color, and it is the necessary conformity of AgNPs synthesis
Summary
Biopolymers are considered an ideal candidate for nanotechnology’s recent advent due to the biocompatibility, reducing/capping ability, and different physicochemical properties, especially nontoxicity to an environment. They are highly edible as well as biodegradable films in food packaging. The high recyclable natural biomoleculesbased packaging materials like fatty acids, amino acids, and polysaccharides are convenient environmental agents than petrochemical-based polymers. Biopolymer films and coatings are used for many applications: it serves as the best food packaging material, minimizes food deterioration, extends food life by serving as solute and gas barriers, and acts as various additives (antioxidants, antimicrobials, coloring agents, and nutrients) [1,2,3,4,5]. The biopolymers and papers-associated materials are providing an eco-friendly approach. Many researchers pushed towards the advanced and new approaches for developing antimicrobial papers by administering eco-friendly synthesis processes [12,13,14]
