    Laser Heating Tunability by Off-Resonant Irradiation of Gold Nanoparticles 
    Hormeño, S.; Gregorio-Godoy, P.; Pérez-Juste, J.; Liz-Marzán, L.M.; Juárez, B.H.; Arias-Gonzalez, J. R. (John Wiley & Sons, 2014-01-29)
    [EN] Temperature changes in the vicinity of a single absorptive nanostructure caused by local heating have strong implications in technologies such as integrated electronics or biomedicine. Herein, the temperature changes ...

    Mechanical unfolding of long human telomeric RNA (TERRA) 
    Garavís, M.; Bocanegra, R.; Herrero-Galán, E.; González, C.; Villasante, A.; Arias-Gonzalez, J. R. (The Royal Society of Chemistry, 2013)
    [EN] We report the first single molecule investigation of TERRA molecules. By using optical-tweezers and other biophysical techniques, we have found that long RNA constructions of up to 25 GGGUUA repeats form higher order ...

    Optical Trapping of Single Nanostructures in a Weakly Focused Beam. Application to Magnetic Nanoparticles 
    Rodríguez-Rodríguez, H.; de Lorenzo, S.; de la Cueva, L.; Salas, G.; Arias-Gonzalez, J. R. (American Chemical Society, 2018-08-09)
    [EN] Optical trapping of individual particles is believed to be only effective under highly focused beams because these conditions strengthen the gradient forces. This is especially critical in the beam propagating direction, ...

    Single-Stranded Condensation Stochastically Blocks G-Quadruplex Assembly in Human Telomeric RNA 
    Gutiérrez, I.; Garavís, M.; de Lorenzo, S.; Villasante, A.; González, C.; Arias-Gonzalez, J. R. (American Chemical Society, 2018-05-17)
    [EN] TERRA is an RNA molecule transcribed from human subtelomeric regions toward chromosome ends potentially involved in regulation of heterochromatin stability, semiconservative replication, and telomerase inhibition, ...
