Özet

Silver nanoparticles (Ag NPs) have been used in many studies due to their inhibitory properties on microorganisms such as bacteria and viruses. In recent years, due to global problems such as environmental pollution, the green synthesis (biosynthesis) method is frequently preferred because it is simple and low cost and does not require the use of toxic substances. The aim of this study is to synthesize silver nanoparticles (Ag NPs) from Ceratonia siliqua L. leaves and investigate their antioxidant and immunotoxic properties using Galleria mellonella last instar larvae. The UV spectrophotometer, TEM, XRD and FTIR measurements were used to characterize the Ag NPs. In this study, it was determined that the effects on antioxidant enzyme activities (SOD, CAT, GPx, GST), acetylcholinesterase (AChE) and total hemocyte count (THC) as well as phenoloxidase activity determine their effect on antioxidant defence and the immune system in model organism G. mellonella larvae. We observed that green synthesized Ag NPs accumulate in the midgut of the larvae and led to the increasing of CAT and SOD activities. GST and AChE activities were increased in the fat body of the larvae; otherwise, it was decreased in the midgut. Moreover, increases were found in THC and phenoloxidase activity. Consequently, green synthesized silver nanoparticles led to oxidative stress and immunotoxic effects on G. mellonella larvae.
