Dr. Rojas's research focuses on surface and colloid chemistry and the adsorption behaviors of surfactants and polymers at solid/liquid interfaces. He has studied the viscoelasticity of adsorbed nanolayers by Surface Laser Light Scattering, Surface Plasmon Resonance and Quartz Crystal Microbalance methods. He also uses state-of-the-art techniques such as the interferometric and bimorph surface force apparatuses and the Atomic Force Microscope (AFM) to unveil basic phenomena and interactions in the colloidal and nanoscale domain. His group currently works on the dynamics of enzymatic degradation at the nanoscale; biosensor development; friction and adhesion in polymeric interfaces; adsorption dynamics, nanocomposites from natural products and, the assembly of forest-derived polymers and surfactants.
