Effect of Nanosilver Particles on Procaspase-3 Expressionin Newborn Rat Brain

摘要

Objective Nanotechnology focuses on materials having at least one dimension of less than 100 nanometers. Nanomaterials such as Nanosilver (NS) have unique physical and chemical properties such as size, shape, surface charge. NS particles are thought to in- duce neuronal degeneration and necrosis in the brain. It has been reported that NS parti- cles generate free radicals and oxidative stress which alters gene expression and induces apoptosis. This study was designed to evaluate whether the detrimental effect of NS parti- cles is through the activation of Procaspase-3 during fetal neural development.
