In Situ Generation of Bimetallic Nanoparticles in Cotton Fabric Using Aloe Vera Leaf Extract, as a Reducing Agent

Abstract

In the present work, bimetallic nanoparticles were in situ generated in cotton fabrics using Aloe Vera extract as reducing agent. The nanocomposite cotton fabrics were prepared, individually with 5 mM concentrations of Ag and Cu salt solutions and equi.molar concentration of their combination, characterized by FTIR, XRD, SEM, EDX, and antibacterial tests. FT-IR studies reveal that nitro compounds and hydroxyl groups are involved in reduction of the metal salts into their metal nanoparticles. The nanocomposite cotton fabrics have shown good antibacterial activity for five bacteria. These fabrics can be used for dressing, wound healing, packaging, and medical applications.
