Clinical Transfer Imaging - Activities

PFIC has the particularity to develop the transfer of photonic imaging for clinical applications in R&D division. R&D division is focused on the development of photonic tools mainly in collaborations with surgeons and pathologists to support tumor limits control, lymph nodes identification and flap perfusion viability. Our R&D division is engaged in ex vivo and in vivo clinical programs since 2008 with:

Microscopy - Equipments

SP8 Confocal Microscope (Leica)

The system in reverse configuration is equipped with 4 lasers covering excitation wavelengths 405, 488, 561, and 638nm. Fluorescence signals are collected on 2 PMT detectors and 2 high-sensitivity HyD detectors. A thermostatic and CO2-regulated chamber and a motorized turntable are installed on the microscope for kinetic studies and XYZT acquisitions.

This microscope is suitable for confocal, wide-field and/or multi-position imaging.

Cytometry & Mass imaging - Equipments

Mass cytometer HELIOS (Fluidigm)

As a complementary tool to flow cytometers, the mass cytometer considerably increases the number of parameters that can be analyzed (>40), while eliminating the problems of overlapping fluorescence spectrums observed with conventional cytometry.
