Nanoparticles used to developantibacterial fabric

August 23, 2014

Amirkabir University researchers have developed an antibacterial fabric that has application in textiles and medical products by using copper nanoparticles.

Majid Montazer and Nahid Hemmatinejad, faculty members of the university, and Ali Seddiqi, a PhD student of the university in nanotechnology, were researchers of the project.

Seddiqi said the new product is an appropriate alternative to expensive antibacterial fabrics made from silver nanoparticles.  

He explained that in the study, a simple, inexpensive synthesis of copper nanoparticles on cotton fabric is carried out by using a chemical reduction method.

"Copper sulfate as a precursor, citric acid as a stabilizing and protective agent against aggregation and oxidation of nanoparticles, and sodium hypophosphite as a reducing agent were used," he said.

The researcher noted that the excellent antibacterial, antimicrobial and antifungal behaviors of fabrics containing copper nanoparticles even after 30 washing cycles confirm their potential for use in textiles and medical products such as stitches and sterile bandages.

Results showed the high stability of the nanotreated fabric.

Sediqi further said the nanocopper-treated fabrics showed reasonable hydrophobicity, adding that the product can also be used in wound healing and preventing infections in patients.Nanoparticles used to developantibacterial fabric
