Arnau Farré, co-founder of IMPETUX OPTICS, has been awarded with the Justiniano Casas second prize for research in Optical Imaging, 4th edition, for his thesis, entitled “Momentum measurements of single-beam traps and quantitative holographic experiments: two sides of the same coin”. The award ceremony was hold on the 29 of August in Santiago de Compostela during the meeting of the 23rd Congress of the International Commission for Optics (ICO).

Time dependence of trap position (top), force signal (middle) and Ca2+ fluorescence signal (bottom) recorded during a membrane tether pulling experiment. The force and Ca2+ ion channel activity signals exhibit negative correlation.

Force and displacement data for two beads stimulated at frequencies of 4 Hz and 0.25 Hz. The progressive reduction of the beads displacement is in concomitancy with an increase of the applied force and loading rate.
