Effect of β-Cyclodextrin Stabilized Silver Nanoparticles on Gills, Kidney, Liver of Danio rerio

Abstract

The silver nanoparticles (AgNP) are applied broadly in medical applications due to their antimicrobial property. However, the toxicity (uptake, translocation, and accumulation) of these AgNPs nanomaterial has not been much explored. Also, cyclodextrin has been used for different pharmaceutical applications due to its various potential properties. Therefore, the toxicity of these AgNPs and cyclodextrin in the model organism such as Danio rerio could be crucial for future nano-drug studies. The main aim of the present research work is to synthesize, characterize biopolymeric silver nanoparticles, and perform histopathological studies of synthesized silver nanoparticles on Danio rerio. The silver nanoparticles of 130nm size have been synthesized successfully using β-Cyclodextrin (β-CD) at room temperature. The various analytical applied to characterized the β-Cyclodextrin (β-CD) reduced silver nanoparticles (β-CD)-SNPs. A histopathological study has been conducted to evaluate the toxicity effect of the synthesized (β-CD)-SNP on the animal model Danio rerio. The (β-CD)-SNPs conc. 30µl/l is affecting and damaged gills and kidney the Danio rerio organs (gills, kidney) exposed after 10 days, yet the liver was found to be healthy. In conclusion, the Danio rerio gills, kidneys, and liver are sensitive to the 130nm-sized (β-CD)-SNPs. The nanoparticles' toxicity depends on concentration; less concentration (30µl/l) accumulates and is absorbed efficiently than the higher concentration (300µl/l). However, no morphological changes were observed on Danio rerio.
