The Biophotonics Group at the University of Geneva develops nonlinear optical techniques for imaging and sensing. In the framework of the COST Nanospectroscopy action, 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. The group is equipped with two multi-photon microscopes with spectral detection capability, and a cell culture facility. For further information, please contact Luigi Bonacina.


The Laboratoire d'Optique Biomedicale (LOB) is a research group at École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland. LOB has an established expertise in optical techniques (in imaging as well as in spectroscopy) and its projects are focused on the development of optical structural and functional imaging modalities aiming applications in life sciences and medicine.

Main topics of interest are:

  • Coherent Imaging
    • Optical coherence microscopy (OCM)
    • Doppler-optical coherence microscopy
    • Photo-thermal optical coherence microscopy (Poli-OCM)
    • Quantitative phase imaging
  • Super-resolution microscopy
    • Super-resolution optical fluctuation imaging (SOFI)
  • Correlation spectroscopy
    • Optical coherence correlation spectroscopy (OCCS)
    • Fluorescence correlation spectroscopy (FCS)
    • Nonlinear correlation spectroscopy (NCS)
