The relentless advances made in nanotechnology during the last years call for a multidisciplinary, cross-sectional approach, from the design of new materials to their final application. NALS 2020 intends to establish synergies, foster long-lasting collaborations, and contribute to a fruit-full academia-industry liaison, to work together on the development of disruptive nanomaterials based techniques and devices for applications in the fields of Medicine, Biology, and Environment, among others.
