About Dr Salvador Tomas

Research interests

  • Dr Tomas’ research focuses on the study of molecular recognition and self-assembly phenomena in aqueous media. Current efforts are directed to understand the emerging properties in complex systems by the systematic stepwise increase of the system complexity. The general approach is based on the use of well designed, synthetic molecular receptors and ligands that allow a rigorous characterization of their self-assembling properties. Dr Tomas’ research can be summarized in the following lines:

    • Study of the molecular recognition properties of metalloporphyrins in aqueous media.
    • Developing sensor materials in aqueous solutions based on self assembled molecular receptors.
    • Developing stimulus-responsive, self-assembled long range assemblies (e.g. hydrogelators).
    • Using synthetic models to probe molecular recognition (receptor clustering, ligand binding, cooperative effects) in or near lipid membranes.
    • HPLC as a high-throughput method to characterise drug-lipid membrane interactions and drug-membrane protein interactions.
    • Study of micro and nanocompartmentalized systems (i.e. lipid vesicles) and the role they played in the origin of life
