New method to predict how nanoparticles will react in the human body

At the nanoscale chemistry is different and nanoparticles don’t behave like normal particles. Nanoparticles tend to be more chemically reactive than ordinary-sized particles of the same material, making it hard to predict how they will act under different conditions and raising serious questions about the use of such particles – particularly inside the human body. Researchers have now developed a method for predicting the ways nanoparticles will interact with biological systems – including the human body – that could improve human and environmental safety in the handling on nanomaterials, and have applications for drug delivery.
