Biosynthesis and study of antibacterial copper-based nanoparticles

Motivated to develop antibacterial cotton fabrics for medical applications, a simple, cheaper, and eco-friendly technology was employed for the generation of copper-based nanoparticles (CuBNPs-CuNPs and Cu2ONPs) in cellulose-based white cotton cloth, using Tinospora cordifolia (TC) leaf broth as reductant at ambient conditions. The presence of effective reducing agents in the TC leaf extracts was exploited for in situ generations of CuNPs and Cu2ONPs in cotton fabrics. The CuBNPs were analyzed by FTIR, SEM-connected EDX, TG-DTG, DSC, and XRD. The CuBNCFs were found to be in spherical shape with an average size of 120 nm. The XRD studies indicated the face-centered cubic (FCC) crystalline structure of CuBNPs. The in situ-generated CuBNPs in NCCFs showed good thermal stability, antibacterial activity, and mechanical properties. Based on the properties, the CuBNCFs can be considered for pillows, beds in hospitals, and packing materials.
