Bio
Our current research emphasizes on molecular mechanisms of toxicity of different kinds of organic and inorganic nanomaterials. We are also evaluating that how these effects may be affected by the nanomaterials unique physico-chemical properties including crystalline nature, sizes and surface chemistry. Owing to their unique physico-chemical properties, nanomaterials can cause biological responses such as inflammation, free oxygen radical generation, oxidative stress, DNA damage, gene expression and apoptosis. Expected outcomes of this research will not only help to improve the nanomaterials safety strategies for the protection of human health, but will also help for biomedical and pharmaceutical applications.
