Luigi Bonacina started his academic career at the University of Milan (bachelor in Physics and Master in Optical Physics). He then moved to Switzerland for starting a PhD at the EPFL in Lausanne with a research in the field of ultrafast molecular spectroscopy. Successively, he joined the University of Geneva where in 2011 he got a tenured position as a senior lecturer at the Applied Physics Department, Biophotonics laboratory . His scientific research activities are based on the development and application of novel nonlinear and coherent optical approaches to nanotechnology for imaging and photo-interaction with biological samples.

Scientific interest in the action

The Biophotonics Group at the University of Geneva headed by Prof. Jean-Pierre WOLF develops nonlinear optical techniques for imaging and sensing. In the framework of the NanoPhoto network, the group wants to further investigate the application of Harmonic Nanoparticles (HNPs) for nanomedicine applications. HNPs are inherently nonlinear particles based on different inorganic noncentrosymmetric nanocrystals displaying very efficient nonlinear response at the second and third harmonic. Such particles open a series of alternative detection possibilities simply not accessible with the present generation of fluorescent dyes and quantum dots as they can respond to excitation from the ultraviolet to the infrared, they possess a coherent and polarization dependent response, and they are highly photo-stable.

Research infrastructures

The group is equipped with several femtosecond amplified systems and with two multi-photon microscopes with spectral-detection and polarization-resolved capabilities at the second and third harmonic. The laboratory also features a cell culture facility for living sample preparation and storage.
