摘要
In the present study,green synthesis of silver nanoparticles(AgNPs)were prepared by using Acalypha indica(AI)plant aqueous extract,which is used as a reducing and capping agent.The surface plasma resonance of AI-AgNPs was obtained at 436 nm by the ultraviolet-visible(UV-Vis)spectrum,which confirmed the formation of AI-AgNPs.Fourier transform infrared(FTIR)spectrometer studies revealed that phenolic and carbonyl groups are involved in the reduction of Ag+to Ag.The transmission electron microscope(TEM)micrograph reveals that the size of green synthesized AI-AgNPs was obtained in the range of 18.7 with spherical morphology.The negative zeta potential of-16.1 mV of AI-AgNPs indicates the surface charge of the AI-AgNPs as negative the colloidal formulation is moderately stable.The current investigation additionally encompasses the demonstration of the potent antimicrobial efficacy of AI-AgNPs against Escherichia coli,Salmonella typhi,Staphylococcus aureus,and Streptococcus pyogenes.Furthermore,the study involves subjecting the green synthesized AI-AgNPs to assessments of antioxidant activity using,NO,and H2O2 methodologies,anti-cancer studies,DNA binding studies,and photocatalytic dye degradation.
