Area Of Science
- Materials Science
- Textile Engineering
- Nanotechnology
Background
- Increased demand for antimicrobial textiles post-COVID-19 pandemic.
- Need for rapid, cost-effective, and scalable methods for textile functionalization.
Purpose Of The Study
- To develop a convenient, room-temperature method for applying antimicrobial silver coatings on textiles.
- To evaluate the antimicrobial efficacy and biocompatibility of silver-coated cotton and polyester.
Main Methods
- Electroless silver plating at room temperature on cotton and polyester fabrics.
- Characterization using optical microscopy, scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS).
- Biocompatibility testing with L929 fibroblasts and HaCaT cells.
- Antibacterial testing against Escherichia coli.
- Antiviral testing with SARS-CoV-2 and Feline Calicivirus (a norovirus surrogate).
Main Results
- Successful application of silver coatings on cotton and polyester without nanoparticle formation.
- Increased surface roughness and hydrophobicity observed on Ag-coated textiles.
- Approximately 80% biocompatibility with tested cell lines.
- Strong antibacterial activity against Escherichia coli.
- Rapid viral reduction: 100% for SARS-CoV-2 on cotton (30 min) and polyester (1 h); >60% for Feline Calicivirus in 5 min, 100% in 1 h for both.
Conclusions
- A fast, efficient, and low-cost method for producing antimicrobial textiles via silver plating.
- Silver-coated textiles demonstrate broad-spectrum antimicrobial activity and good biocompatibility.
- Potential for widespread use in medical and healthcare settings.

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...
The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the...
