This paper deals with the difficulties that law encounters in keeping up with the rapid development of technosciences. It is a matter of reconsidering the legal categories in the light of the protection needs, being aware that an approach capable of facing uncertainty in many ways is required. In the field of emerging technologies there is the need to direct behavior, to ascribe responsibilities on the basis of a set of coherent rules, to manage risks, to ensure the communication of information, to guarantee fundamental rights, to protect the health of human beings and the environment. Legal regulation, within a heterogeneous and complex normative and institutional framework, tends to be structured in an open, diversified and flexible manner.
Keywords: Law and technoscience, transformation of legal concepts, responsibility, precautionary principle, forms of regulation.
