    Welcome to the Optical Nanomanipulation Lab developed by Dr.  J. R. Arias-González, now at the Universitat Politècnica de Valencia (Spain).

    Our research focuses on Molecular Biophysics and biocompatible nano-systems, with a strong bond to both Mesoscopic Physics and Biological Chemistry. We use theory and experiments based on the manipulation of single molecules.

    The phenomena inside a cell happen molecule by molecule. Nucleic acids, as the software, and proteins, as the hardware, comprise a stochastic but coordinated and precise set of macromolecules that are accessible to optical trapping techniques.

  • HISTORY & GALLERY

    The Optical Nanomanipulation Lab was established in 2005 at the Universidad Autónoma de Madrid. It was then moved to the Centro Nacional de Biotecnología, CSIC, in 2007 and to IMDEA Nanoscience, on the same campus, in 2012. The laboratory, developed by Dr. J. R. Arias-Gonzalez, entailed the first experimental environment for single-molecule manipulation experiments by optical tweezers in Spain.
