The first international conference on Fluorescent Biomolecules and their Building Blocks – Design and Applications (FB3) will be held at Chalmers University of Technology in Göteborg, Sweden, between July 5th and July 8th, 2012. This first FB3 meeting will gather experts from around the world to discuss the state-of-the-art in the development and use of fluorescent probe molecules for biomolecular and nanotechnological systems. This rapidly evolving field deserves a dedicated venue and we feel that our community would benefit from a vigorous discussion and exchange of ideas related to its progress and future directions. The meeting will bring together established scientists, younger investigators, students and postdocs. To enable focused discussions, promote exchange of ideas and facilitate networking, the number of participants will be limited to approximately 150.
