چکیده

Silver nanoparticle (AgNPs) are largely used as bio-markers and biodelivery vehicles in the medicine, pharmacy and in cosmetic products. However, for the therapeutic application and drug delivery of AgNPs, it is essential to know the distribution and local or systemic toxicity associated with them. For this purpose, this study was carried out to assess the potential consequences of skin injection of nanochelating based synthesized AgNPs on the mice models.Nanochelating technology was used to design and synthesize the AgNPs. The histopathological findings in skin and tissue of micemodels have been assessed via histopathological analysis.All samples were visualized by an independent pathologist. The results of each sample have reported as follow, micrograph of the skin cells shows the normal architecture and cells in all samples. Moreover, histopathological evaluation of samples shows normal without any significant pathological changes compared to control groups in volume of derm and epiderm, and the number of fibroblast, neutrophil, and macrophage.In summary, this study has observed no obvious decline of immunological performance and morphological signs of skin damage in the mice caused by nanochelating based AgNPs exposure. These findings could provide a fundamental understanding of the intrinsic toxicity associated with nanochelating based AgNPs in biological models. Moreover, this study would arisetypical attentions on the future applications of nanochelating based AgNPs on human, which is valuable for short-term and low-dose treatment in nanomedicines.
