Stable colloidal suspension of magnetic nanoparticles is challenging owing to both van der Waals forces and magnetic dipolar interactions. Thus, it is essential to coat magnetic nanoparticles with a surfactant during chemical synthesis in order to prepare well-dispersed nanoparticle colloid. In the present study, cobalt nanoparticles (∼15 nm in size) were(More)
The synthesis of gold nanoparticles using citrate reduction process has been revisited. A simplified room temperature approach to standard Turkevich synthesis is employed to obtain fairly monodisperse gold nanoparticles. The role of initial pH alongside the concentration ratio of reactants is explored for the size control of Au nanoparticles. The particle(More)
We report a case of 14-year-old male, who presented to us with complaints of severe pain in abdomen, vomiting, and inability to pass feces and flatus. He was diagnosed as a case of peritonitis after careful history, examination, and investigations. The exact cause of peritonitis was not known. Exploratory laparotomy was done, and it was found that there was(More)
