Crystallography is a mature scientific discipline, which has contributed, in the recent past, to the development of drugs, to the understanding of the biological activity of proteins and nucleic acids, to the comprehension of the unique properties of crystals at the nanometer scale for diagnosis and drug-delivery and to shedding light on complex hierarchical organic-inorganic composites such as bone and enamel.The purpose of the 2012 International Insubria Summer School is to explore the multiple aspects of crystallography: the world of crystallization, the more traditional and advanced experimental and computational techniques and other complementary methods, which will be specifically focussed to the applications on health- and bio-sciences.A full intensive week will be organized under the guide of internationally recognized experts in the field.
