Optoacoustic phenotyping of cells and tissues

''
Résumé:
My last 15 years in academia have been devoted to research in opto-acoustic technologies, whereby acoustic waves are generated and/or detected by lasers, and to their application to life sciences. I first will describe the theoretical aspects of opto-acoustic technologies. Then I will describe the principle of the acoustic probing of mechanical contacts and detail how this approach can be translated to single cell imaging. I will also demonstrate a complimentary approach to cell biophysics, where I propose a new method to probe the thermal properties of cells. The last part of this presentation will be devoted to acoustic imaging of tissues with spontaneous Brillouin scattering, with applications to tumours and mineralized tissues. I will conclude by presenting my future research directions. In particular I will detail our work on plant mechanics that allowed us to create the first biobased phononic material.
