New UCLA method quickly IDs nanomaterials that can cause oxidative damage to cells
Date:5/3/2012

d play an important role in advancing nanomaterial safety testing in the 21st century to a preventative strategy, rather than waiting for problems to emerge," Nel said.

Another major advantage of an approach based on the assessment of nanomaterials' properties is that one can identify those properties that could potentially be redesigned to make the materials less hazardous, the researchers said.

The implementation of high-throughput screening is also leading to the development of computer tools that assist in prediction-making; in the future, much of the safety assessment of nanomaterials could be carried out using computer programs that perform smart modeling and simulation procedures based on electronic properties.

"We can now further refine the testing of an important class of engineered nanomaterials to the level where regulatory agencies can make use of our predictions and testing methods," said Haiyuan Zhang, a postdoctoral research scholar at the Center for Environmental Implicatioons of Nanotechnology at UCLA's CNSI and the lead author of the study.
