Nano-toxicology: Wolf in Sheep's Clothing?
With the increased use of nanoparticles in several consumer products and pending applications in a range of fields from medicine to ink, the safety of these unique materials is increasingly becoming a concern. In addition to their novel physical and chemical properties, their behavior in biological systems and an environment is rather different. The current approaches to evaluating their adverse effects on biological systems are the ones that are developed for molecules and it is very clear that the approaches developed for molecules are suitable for the NPs. The present review article reveals pros and cons of the NP that leads to toxicology.
