| In order to fully understand whether a nanoparticle has deleterious effects on human health, it is first neccesary to understant its interaction with living tissue at the cellular level. Observations of different classes of nanoparticles reveals that not all nanparticles are deleterious to cell developement. In fact clays can be benefitial and we show that it can enhance cell adhesion and protein self organization, in many cases. Mettalic nanoparticles, on the other hand can be quite toxic and interfere with normal cell function. Here the rate of penetration, as well as the mechanism does depend on particle size. We show that the presence of nanoparticles do not prevent the cells from dividing. On the other hancd certain basic functions, such as migration, morphology, and mechanical properties of both cell and ECM are significantly affected. |
