The Physical Nanochemistry Group, composed of physical chemists, organic chemists, and physicists, is interested in the development and modelling of nano-sized colloidal systems, and in the study of their corresponding physicochemical properties and correlations with molecular concepts. The development of colloid chemistry has been enormous over the last few decades, driven in part by improvements in colloidal nanoparticle synthesis methodologies and the manipulation of nanoparticle surface functionalities with specific amphiphilic and supramolecular moieties. This has allowed not only exquisite control of the morphology of the nanostructures, but also the creation of new assemblies with diverse organizational motifs. At present, the group has two main lines of research focused on the development and modelling of: 1) nanoparticles of inorganic nature, specifically metals and metal oxides, with improved optical and magnetic properties that may have relevant technological applications in the area of new materials development, chemical sensing, catalysis, or biomedicine and 2) nanoparticles of organic nature, specifically lipidic, aimed at the nanovectorization of nucleic acids with potential biomedical applications, key in the development and optimization of new vaccines (such as Pfizer and Moderna's vaccine against SARS-CoV-2) and new protocols for gene therapy against different diseases. This research group, therefore, focuses on the search for new physicochemical perspectives for the design of nanometric devices with applications in a wide variety of fields.
