“…Similar behavior was obtained by several other authors in works that incorporated AgNPs into polycotton in different ways. [53][54][55][56][57][58][59][60] For Polycotton AgNP-OP, the formation of a smaller amount of Ag nanoparticles with average size higher (126.9 ± 19.5 nm) than the than Polycotton AgNP-CS were observed. In addition, there is a homogeneous distribution of micrometric crystals with Since Ag-based antimicrobial additives caused distinct surface interactions in polycotton fibers, it is expected that this difference will be reflected in their physical, chemical and biological properties.…”

Pathogens (bacteria, fungus and virus) are becoming a potential threat to the health of human beings and environment worldwide. They widely exist in the environment, with characteristics of variety, spreading quickly and easily causing adverse reactions. In this work, an Ag-based material is used to be incorporated and functionalized in polycotton fabrics using pad-dry-cure method. This composite proved to be effective for inhibiting the SARS-CoV-2 virus, decreasing the number of replicates in 99.99% after an incubation period of 2 minutes. In addition, it caused 99.99% inhibition of the pathogens S. aureus, E. coli and C. albicans, preventing cross-infections and does not cause allergies or photoirritation processes, demonstrating the safety of its use.

“…Silver NPs have contributed significantly to advances in medical textiles that include the production of wound dressings and protective coatings for medic devices [133]. In fact, the combination of these NPs with biocomposites is the most explored, with exceptional bactericidal properties being identified in cotton-, linen-, sugarcane bagasse-, silk-and jute-reinforced composites [13,[81][82][83][84][85]. The bimetallic NPs comprehend those NPs that combine more than one metal or are produced from metallic alloys.…”

“…Even though biocomposites on their own have been reported in medical textiles [10], the addition of specialized biomolecules with particular properties, such as antimicrobial, anti-inflammatory, analgesic, sedative, anti-oxidative, UV-protection or chemical stability, to name a few, have demonstrated improved performance on specific biomedical applications. Biomolecules such as peptides, antibiotics, nanoparticles (NPs) or plant extracts functionalized onto biocomposites contribute significantly to their biocompatibility towards host cells, while improving other dormant material properties [11][12][13][14][15]. These combinations have been desirable for prospective applications in sutures, coatings for cell culture and drug delivery matrices, as well as for 3D scaffolds for ligaments, bone, cartilage, skin and vasculature engineering [10].…”

Biofunctionalization of Natural Fiber-Reinforced Biocomposites for Biomedical Applications

et al. 2020

View full text Add to dashboard Cite

In the last ten years, environmental consciousness has increased worldwide, leading to the development of eco-friendly materials to replace synthetic ones. Natural fibers are extracted from renewable resources at low cost. Their combination with synthetic polymers as reinforcement materials has been an important step forward in that direction. The sustainability and excellent physical and biological (e.g., biocompatibility, antimicrobial activity) properties of these biocomposites have extended their application to the biomedical field. This paper offers a detailed overview of the extraction and separation processes applied to natural fibers and their posterior chemical and physical modifications for biocomposite fabrication. Because of the requirements for biomedical device production, specialized biomolecules are currently being incorporated onto these biocomposites. From antibiotics to peptides and plant extracts, to name a few, this review explores their impact on the final biocomposite product, in light of their individual or combined effect, and analyzes the most recurrent strategies for biomolecule immobilization.

“…Silver ions and silver compounds have toxic properties in some bacteria, viruses, algae, and fungi such as silver nitrate and sulfadiazine. Some researchers reported that silver particles can attack bacterial cells causing cell damage and killing the bacteria [1][2][3][4][5]. Silver particles in the form of nanoparticles (AgO), oxides or in the form of ions (Ag + ) have a good antibacterial ability.…”

NOVEL COMPOSITE OF SILVER-BACTERIAL CELLULOSE (Ag-BC) FROM SIWALAN SAP (Borassus flabellifer) AND ITS ANTIBACTERIAL ACTIVITY

Recently, a wound healing from natural composite with excellent properties is in a high demand. In this study, a novel composite of bacterial cellulose made from Siwalan sap (Borassus flabellifer) was achieved. Siwalan is a common plant in Java Island of Indonesia and the application is very limited for beverage only. This study aims to determine the effect of the AgNO3/NaBH4 concentration ratio in the development of Ag-BC composites and its antibacterial properties from Siwalan sap. Ag-BC composites were prepared by impregnating the silver solution into the BC matrix through the reduction process with NaBH4. Characterization of Ag-BC composites conducted using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), and Energy Dispersive X-ray (EDX). Antibacterial assay was performed using disc diffusion method against Salmonella typhimurium (Gram-negative) and Staphylococcus aureus (Gram-positive) bacteria. The characterization of Ag-BC composite shows the nanostructure of BC with a length of fiber around 35-60 nm in width. The SEM-EDX micrograph showed that silver particles were impregnated into the BC matrix. Antibacterial activity test results showed that the Ag-BC composite had the ability to inhibit the bacteria S. typhimurium and S. aureus with good inhibition. This result showed the potential application of Ag-BC composite from Siwalan plant as a natural material for medical and pharmaceutical purpose, especially as an antibacterial agent.
