Towards a classification strategy for complex nanostructures

The range of possible nanostructures is so large and continuously growing, that collating and unifying
the knowledge connected to them, including their biological activity, is a major challenge. Here we
discuss a concept that is based on the connection of microscopic features of the nanomaterials to their
biological impacts. We also consider what would be necessary to identify the features that control their
biological interactions, and make them resemble each other in a biological context.
