Research explores interactions between nanomaterials, biological systems
Date:6/19/2009

s such as suntan lotions, for instance, may be coated with a water-repelling polymer to reduce direct contact with human skin. An extension of this principle uses polymers and detergents to decrease cellular uptake. However, there is the potential that when the coating wears off, the material may become hazardous. It is therefore important to consider improving the stability of coating substances. Coating nanoparticles with protective shells is also an effective means of preventing the breakup of materials that could release toxic substances upon dissolution.

"Instead of waiting for knowledge to unfold randomly, we can already begin to view the events at nano-bio interface as a discoverable scientific platform that can be used for setting up a deliberate inorganic-organic roadmap to new, better and safer products," Nel said. "What we can identify by understanding the rules that shape the nano-bio interface will have a massive impact on the ability to develop safe nanomaterials in the future."
