nanoKOMIK project proposes the creation, production and dissemination of the first participatory nanofiction comic in 2016. In an initial phase, youngsters aged between 12 and 18 have been involved in a free creative process where they created their female and male comic superheroes, providing them with nanopowers through astonishing features acquired by matter thanks to nanoscience and nanotechnology. With six science&comic workshops for youngsters and a special one for high school art and science teachers, finally, more than a hundred students from France and Spain participated and presented their work in the nanoKOMIK challenge. In a second phase, most original ideas will be recreated in a professional comic which will be distributed among the general public via the publication of a comic-book and an itinerant exhibition.
