Abstract:

The phyto-fabrication of nanoparticles offers an eco-friendly route to novel functional materials. This study demonstrates the green synthesis of silver nanoparticles (AgNPs) using Aloe vera (L.) Burm.f. extract and their incorporation into an Eri silk fibroin (ESF) film to create a novel antimicrobial biomaterial. The AgNPs and the resulting composite films were characterized via UV-Vis, FTIR, and SEM-EDX analyses. Incorporating the green-synthesized AgNPs significantly enhanced the film's physical properties, resulting in high porosity (up to 88.46%) and an optimal water vapor transmission rate (2503.19 g/m²/day). The final ESF-AVAg composite film exhibited potent, broad-spectrum antimicrobial activity. Specifically, the Zone of Inhibition (ZOI) area for the optimal concentration (AVAg6) was 13.00 mm² against Escherichia coli, 13.69 mm² against Staphylococcus aureus, and 17.55 mm² against Candida albicans, significantly outperforming the controls. This work successfully bridges sustainable green synthesis with biomaterial engineering, demonstrating that Aloe vera-derived AgNPs can be effectively integrated into a silk fibroin matrix to produce a high-performance antimicrobial film.

Antimicrobial Effectiveness

Antimicrobial Effectiveness

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Biofilms

Biofilms

Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

Surface Membrane Barriers

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
