Green synthesis of silver nanoparticles from Curcuma longa L. and coating on the cotton fabrics for antimicrobial applications and wound healing activity

Abstract

The cotton fabrics are a cosmopolitan in usage due to their extraordinary features. The clothes are a very good medium for the growth of pathogenic microorganisms. The nanoparticles have diverse benefits in the biomedical field like drug carrier and as antimicrobials. The current investigation was aimed to synthesize the metallic silver nanoparticles (AgNPs) from the aqueous extract of Curcuma longa leaf and evaluating their antimicrobial and wound healing potential of AgNPs coated cotton fabric. The synthesized AgNPs were characterized by HR-TEM and FT-IR examinations. The formulated AgNPs were coated with cotton fabrics to test their efficiency against the pathogenic microorganisms. The existence of AgNPs in the cotton fabrics was confirmed via the SEM along with EDX analysis. The antimicrobial potential of fabricated AgNPs and its coated cotton fabrics was inspected against the human pathogenic strains. The wound healing efficacy was examined in the L929 cells. The HR-TEM analysis proved the existence of spherical shaped AgNPs. In the antimicrobial activity, the CL-AgNPs loaded cotton fabric was exhibited an appreciable decrease in the growth of pathogenic microorganisms. The crude extract, as well as formulated AgNPs, also exhibited the noticeable antimicrobial potency against the S.aureus, P.aeruginosa, S.pyogenes, and C.albicans. The AgNPs loaded cotton fabrics was displayed the potent wound healing activity in the fibroblast (L929) cells. Consequently, it was concluded that the formulated AgNPs from C.longa coated cotton fabrics may be utilized for the variety of applications in hospital patients and even medical workers to prevent the microbial infection.
