The main objective of the first thematic area is to develop a framework for classified engineered nanoparticles based on the existing data utilising pattern recognition methods.

This includes:
• Collecting and evaluating the existing data (physicochemical and toxicity data).
• Developing statistical procedures for data evaluation.
• Exploring the physico/chemical and toxicity data with pattern recognition techniques (the characterisation and classification techniques) to identify classes of similar properties/toxicity.
• Launching a publicly available database with high quality (evaluated) empirical data.
