As an intern in IVIC, I worked as a lab analyst in a study regarding macromolecular crowding, employing techniques such as dynamic light scattering (DLS), refractometry and fluorescence spectrometry to characterize differences in the behavior of latex nanoparticles in an increasingly crowded environment.After some time, I received the task of instructing new interns and employees on how to use the equipment necessary for the techniques previously mentioned. Thanks to my experience and performance in this internship, by the time it ended I was accepted to work on a thesis project regarding the interactions of nanoparticles with cellular mediums.
