Toxicology is an area of science that considers to protect ourselves from substances around us harmful to human health and the environment, and to maintain our safe life. To put this into execution, the division has played a central role to evaluate their biological safety.

Our recent study includes comprehensive gene-expression analyses to develop a method for predicting toxicity to humans, testing method development to correctly evaluate biological effects of nanomaterials that are becoming widely used as new materials, and basic research that supports them.
