Welcome to the website of the “Group of Nanoparticles and Nanocomposites” (N&N) from the Institute of Materials Science of Barcelona (ICMAB-CSIC). We are located at the campus of the Autonomous University of Barcelona. We have very diverse research interests but our main focus is the controlled and rational synthesis of inorganic and hybrid (inorganic-organic) nanoparticles and nanocomposites as well as the study of their structural-functional properties. Among others, we are currently interested in the stabilization of metastable phases, the preparation of core-shell nanoparticles, stable colloidal dispersions and porous nanocomposites. We must confess a soft spot for magnetic systems…More recently, the N&N group gained interest in (nano)biomaterials. We are currently working with nanocellulose of bacterial origin, biodegradable nanocapsules and we also employ the  model organism C.elegans to study the interactions of nanoparticles with biological systems. Basically, we aim at the applicability of our materials in two main fields:
