“…Further, the films demonstrated extensive antimicrobial properties in comparison with the blank chitosan-poly(vinyl alcohol) film. The elaborated film is recommended for application in food biotechnology [ 103 ]. Similarly, a chitosan-based film with anthocyanin-rich extract from black rice had strong antioxidant activity, antimicrobial effect, and different color responses to various conditions.…”

Antibacterial chitosan films, versatile and eco-friendly materials, have garnered significant attention in both the food industry and medicine due to their unique properties, including biodegradability, biocompatibility, and antimicrobial activity. This review delves into the various types of chitosan films and their distinct applications. The categories of films discussed span from pure chitosan films to those enhanced with additives such as metal nanoparticles, metal oxide nanoparticles, graphene, fullerene and its derivatives, and plant extracts. Each type of film is examined in terms of its synthesis methods and unique properties, establishing a clear understanding of its potential utility. In the food industry, these films have shown promise in extending shelf life and maintaining food quality. In the medical field, they have been utilized for wound dressings, drug delivery systems, and as antibacterial coatings for medical devices. The review further suggests that the incorporation of different additives can significantly enhance the antibacterial properties of chitosan films. While the potential of antibacterial chitosan films is vast, the review underscores the need for future research focused on optimizing synthesis methods, understanding structure-property relationships, and rigorous evaluation of safety, biocompatibility, and long-term stability in real-world applications.

The combination of natural polymers and plant extract attracted much attention thanks to its valuable biological activities. This study presents the preparation and characterization of chitosan (CS) film containing Rhodomyrtus tomentosa leaf extract. In which, the Rhodomyrtus tomentosa leaf extract (SLE) with polyphenol‐rich fractions was extracted by an ultrasonic‐assisted extraction method. The prepared chitosan/polyphenol‐rich fractions film (CSPPF) was characterized using infrared (IR) spectroscopy, mechanical testing, scanning electron microscopy (SEM), and water absorption analysis. Antibacterial and anti‐inflammatory activities of the CSPPF were assessed using the agar well diffusion method and nitric oxide (NO) inhibition assays, respectively. Besides, the release of the extract from the CSPPF as well as the drug release kinetics was also tested. The Rhodomyrtus tomentosa leaf extract enhanced the antibacterial efficacy against Escherichia coli and enhanced the anti‐inflammatory activity as well as the swelling ability of the CSPPF. The CSPPF containing 1 wt.% of SLE can inhibit 77.70 % NO with an IC50 value of 19.40 μg/mL.
