Project Description

Microscopy techniques based on vibrational spectroscopy are poised to be part of the next generation of microscopes for biological applications based on their unique chemical contrast and sub-cellular resolution for non-invasive, non-destructive and label free imaging of biological samples as live cells. The project will focus on the development of a fast and low-noise detection system in a setup for microscopic vibrational spectroscopy based on Stimulated Raman Scattering, which is one of the most advanced and sensitive methods for label-free microscopy for bio-imaging. The system will be applied to vibrational imaging of cancer stem cells to unveil their specific bio-chemical signatures. ​ ​​​​

Research Interests

Prof. Liberale's research interests are focused on developing and applying label-free chemical imaging techniques based on vibrationalA spectroscopy (Infrared and Raman micro-spectroscopy) and multi-photon processes (Coherent Raman Microscopy, SHG). One of the mainA aims of this research activity is to unveil specific bio-chemical signatures of cancer stem cells, with a particular focus on understanding theA dysregulation of their lipid metabolism. He is also interested on using high-resolution 3D printing based on Direct Laser Writing for the fabrication of novel micro-optics, towardsA the miniaturization of complex optical systems, and of smart micro-/nano-structures to be used as a probe in nanoscale imaging. ThisA research activity takes advantage from an integrated approach that combines design, micro/nanofabrication and optical techniques.a€‹
