Abstract

This study aimed to evaluate the in-vitro and in-vivo biological activities of newly synthesized nanochelating based silver nanoparticles (AgNPs) in mouse model. Nanochelating technology was used to design and synthesize the AgNPs. The animals studies were including the lethal dose (LD50) determination by the intraperitoneal administration in mice, and determination of liver enzymes levels and hematological parameters. Flow cytometry analysis was used to quantitatively determine apoptosis and necrotic cells in-vitro. The NPs A and NPs B have LD50 = 250 mg/kg and LD50 = 350 mg/kg, respectively and classified as non-toxic. In general, minor alterations were observed in levels of liver enzymes as indicative of liver damage. For blood parameters several factors associated with significant changes in AgNPs treated animals. Regarding animals weight, combination therapy showed more effective to maintain animals weight losses after infection. Flow cytometry results showed that AgNPs induced cell apoptosis-necrosis depends on AgNP size, concentration and exposure time. Cells damage due to AgNPs (A) with lower size (20-25 nm) were relatively more than cells exposed to AgNPs (B) (30-35 nm). The findings support the potent antibacterial activities of nanochelating based AgNPs. Also, the present study showed that nanochelating based AgNPs induce a moderate level of apoptosis/necrosis in mice, and affected several clinical parameters like blood parameters, liver enzymes, and body weight with no definite signs of toxicity.
