The therapeutic properties of tin nanoparticles have been proved in recent years. One of their probable effects is anti‐anemia. In this study, tin nanoparticles were synthesized and characterized in aqueous medium using Ziziphora clinopodioides Lam leaf aqueous extract as the reducing and stabilizing agent. We also assessed the antihemolytic anemia potential of tin nanoparticles (SnNPs) in an animal model of hemolytic anemia. Tin nanoparticles were characterized using many techniques including Fourier transform‐infrared and UV‐visible spectroscopy, X‐ray diffraction (XRD), energy dispersive X‐ray spectrometry, and field emission‐scanning electron microscopy (FE‐SEM). FE‐SEM images showed a uniform spherical morphology in size of 18.12 nm for the green synthesized nanoparticles. According to XRD analysis, SnNPs crystal size was17.94 nm. SnNPs had low cell viability dose‐dependently against human umbilical vein endothelial cell line. in vivo design, induction of hemolytic anemia was done by phenylhydrazine in 40 mice. Tin nanoparticles significantly (p ≤ 0.01) reduced the weight and volume of liver and spleen and the concentration of pro‐inflammatory cytokines, and increased the body weight, anti‐inflammatory cytokines concentration, total platelet, WBC, neutrophil, lymphocyte, eosinophil, monocyte, and basophil counts, and red blood cell parameters compared to the untreated mice. For the biochemical parameters, SnNPs significantly (p ≤ 0.01) increased the concentrations of GPx, CAT, and SOD in serum, liver, and spleen and decreased the concentration of GR in serum, liver, and spleen, and also erythropoietin, ferritin, and ferrous in serum as compared to the anemic mice. The 2,2‐diphenyl‐1‐picrylhydrazyl test showed similar antioxidant activities for SnNPs and butylated hydroxytoluene. The results demonstrate the excellent antihemolytic anemia, hematoprotective, cytotoxicity, and antioxidant potentials of SnNPs compared to other experimental groups.

In recent years, biosynthesis of silver nanoparticles using plant extracts and bioactive compounds has gained much attention. Green synthesis of nanoparticles is eco‐friendly, cost‐effective, and is a promising substitute for the chemical synthesis of silver nanoparticles. Also, the previous experiments have revealed that plants raise the cytotoxicity potentials of silver nanoparticles against several cell lines especially tumor cell lines. The present study confirms the potential of aqueous extract of Glycyrrhiza glabra L leaf grown under in vitro condition for the biosynthesis of silver nanoparticles (AgNPs). Also, in this study, we revealed the antioxidant and anti‐acute T cell leukemia properties of AgNPs against J45.01, Jurkat, Clone E6–1, J.CaM1.6, and J.RT3‐T3.5 cell lines. Silver nanoparticles were characterized and analyzed using common nanotechnology techniques including UV–Vis. and FT‐IR spectroscopy, TEM, and FE‐SEM. DPPH free radical scavenging test was carried out to assess the antioxidant potentials of AgNO3, G. glabra, and AgNPs. MTT assay was used on normal cell line (HUVEC) and acute T cell leukemia cell lines (J45.01, Jurkat, Clone E6–1, J.CaM1.6, and J.RT3‐T3.5) for analyzing of anti‐acute T cell leukemia properties of AgNO3, G. glabra, and AgNPs. FT‐IR analysis revealed antioxidant compounds in the nanoparticles were the sources of reducing power, reducing silver ions to AgNPs. TEM and FE‐SEM images indicated a uniform spherical morphology in size of 20 nm for silver nanoparticles. DPPH test indicated similar antioxidant activities for G. glabra, AgNPs, and butylated hydroxytoluene. Silver nanoparticles had very low cell viability dose‐dependently against J45.01, Jurkat, Clone E6–1, J.CaM1.6, and J.RT3‐T3.5 cell lines without any cytotoxicity on HUVEC cell line. The best result of cytotoxicity property of AgNPs against above cell lines was seen in the case of J.CaM1.6 cell line. Above findings confirm the significant antioxidant and anti‐acute T cell leukemia properties of AgNPs. After confirming these results in clinical trial studies, AgNPs can be used as a chemotherapeutic drug for the treatment of acute T cell leukemia in human.

Metallic nanoparticles have gained significant attention in the area of biomedical technology. Because of its high surface area, metallic nanoparticles are being widely used in various fields including the medical and engineering sciences. One of the valuable applications of metallic nanoparticles especially copper, zinc, and iron nanoparticles is increasing the physiological function of central nervous system. Besides, Iranian people are using the Salvia chloroleuca for neuroprotective properties. In the present research, iron nanoparticles were biosynthesized by S. chloroleuca leaf aqueous extract as reducing and stabilizing agents. Also, we revealed the protective effect of FeNPs in methadone‐treated PC12 cells. FeNPs were characterized and analyzed using common nanotechnology techniques including FT‐IR, UV–Vis. spectroscopy; EDS, TEM, and FE‐SEM. TEM and FE‐SEM images revealed a uniform spherical morphology for FeNPs. In the biological part of the current study, the both treatments of FeNPs significantly (p ≤ 0.01) reduced the cell cytotoxicity and cell death index as well as increased the cell viability and cell proliferation in methadone‐treated PC12 cells. In these treatments, mitochondrial membrane potential significantly (p ≤ 0.01) increased compared to methadone‐induced PC12 cells. DPPH free radical scavenging test was did to evaluate the antioxidant potentials of FeCl3, S. chloroleuca, and FeNPs. DPPH test indicated similar antioxidant activities for S. chloroleuca, FeNPs, and butylated hydroxytoluene. In current experiment, we concluded that iron nanoparticles biosynthesized by S. chloroleuca leaf aqueous extract suppressed methadone‐induced cell death in a dose‐dependent manner in PC12 cells.
