Currently, a hot research topic is developing at the interface between physics, chemistry and materials science from one side and biology and medicine from other side, aiming to provide novel nano-tools for cancer treatment. However, despite advances in pre-operative imaging techniques, there is not a suitable intra-operative technique to provide real-time feedback to surgical oncologist to distinguish healthy tissue from malignant lesions and visualize submilimetrical tumor deposits. It is through a collaborative consortium gathering physicists, chemists, biochemists, biologists, oncologists, surgeons, histopathologists that this project addresses a challenging subject aiming to validate new targeted optical imaging nanoprobes for near-infrared (NIR) real-time image-guided surgery of ovarian cancer. Actually, we will develop targeted contrast agents to bind specifically to the FRα of ovarian cancer cells for enabling “visualization” of ovarian tumors by distinct optical signature in NIR. At the end of project, after their careful evaluation on ovarian cell lines /ovarian tumors xenografts / carcinomatose models, will be in position to proceed in the future as viable contrast agent in real-time image-guided ovarian cancer surgery. We focus our research effort to implement NIR optical nanoprobes containing Food and Drug Administration (FDA) approved compounds as well to promote new related nano-compounds produced in our laboratories. Actually, the development of targeted contrast agent in the NIR wavelengths range is highly relevant and beneficial to cancer surgery as their signal does not compete with background signal of tissue emitted in visible light spectrum and, therefore, a clear and deep difference between healthy tissue and tumoral lesions can be delineated.
