During the last project meeting, held in Sanofi offices near Paris, CUPIDO hosted a workshop focused on the present state of the regulations in nanomedicine. Among the speakers, Patrick Boisseau by ETP Nanomedicine gave a clear overview of the European ecosystem in nanomedicine (here the presentation) and Simon Baconnier from EU-NCL provided useful tips on the European infrastructure to improve translation in nanomedicine (here the presentation). Thanks to all the participants to make the workshop successful, it was a great chance to network with other interesting initiatives in nanomedicine in Europe.
