Abstract	Nanoparticles can potentially cause adverse effects on organs, tissue, cell levels, and protein levels because of their physicochemical properties. Silver nanoparticles (AgNPs) are being used on a wide scale in world consumer markets; their potential hazards for humans remain largely unknown. This study aimed to investigate the intraperitoneal toxicity of AgNPs (26 mg per kg of body weight, 52 mg per kg of body weight, and 78 mg per kg of body weight) over 72 hours in Swiss albino mice. AgNPs induced a significant increase in serum liver injury markers including alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase. Induction of DNA damage was also studied in mice injected with AgNPs. Apoptosis (detected by using the terminal deoxynucleotidyl transferase deoxyuridine triphosphatase nick end labeling assay method) in liver tissue and DNA strand breaks (detected by using the comet assay method) in lymphocytes revealed that a concentration of 78 mg of AgNPs per kg body weight can cause significant apoptosis and DNA damage. The DNA damage and apoptosis raise the concern about the safety associated with application of the AgNPs. Significantly more alterations were induced in the hepatocytes of animals exposed to AgNP doses than in the control animals. The induced histological and apoptotic changes may be due to AgNP toxicity. Immunohistochemical and ultrastructural of AgNP.
