Abstract
The present thesis encompasses a work on the effect of Gold Nanoparticles on the growth, development and behaviour of Zebrafish. In the present times, when science and technology has made progress by leaps and bounds, had at the same time its side effects on the human population as well as on other species. Nanoparticles are particles with the minimum measurement between 1 and 100 nm. Because of their peculiar size and characteristics, nanoparticles are used in very delicate missions in the biomedical field. They have been actively used for the drug distribution, cellular imaging and other diagnosis. These nanoparticles have revolutionized the medical field. Gold nanoparticles being a type of this category have also been widely used for drug distribution, detection and diagnostic methods. But along with these benefits, there are apprehensions that these nanoparticles at the same time may have an affect the growth of the organism. In this work, an attempt has been made to gauze the possible neurotoxic effects of gold nanoparticles on the growth and development of Zebrafish (Danio rerio), particularly its behaviour and axon development.
