Researchers at Islamic Azad University, Yazd Branch, have evaluated the effect of different morphologies of silver nanoparticles on antimicrobial characteristics of cotton fabrics.

Hamed Haji Mirza-Baba, a PhD student in textile chemistry and project researcher, said colloid nanosilver particles were applied to cotton fabric by ultrasonic method in an ambient temperature.

Results of the research showed non-spherical morphologies such as polygonal, prism and hierarchical shapes compared to spherical and disc morphologies exhibited stronger growth inhibitory effect against gram-negative bacterium Escherichia coli and gram-positive Staphylococcus aureus after five washing processes.

The hierarchical morphology showed a good antimicrobial activity of over 91 percent after five washing process.

Germs grow very rapidly by cell division, doubling their population every 20 minutes. They require humidity and an organic medium for growth.

Antimicrobial fabrics can prevent the growth of various microorganisms and therefore, contribute to deodorizing. Antimicrobial products are divided into bactericides (causing destruction of bacteria) and bacteriostats (inhibiting bacterial growth).

Antimicrobial fabrics would be implemented into all hospital-related clothing to drastically reduce the risk of hospital-acquired infections.
