Raman spectroscopy is a valuable and versatile tool used across various fields. Collected Raman light provides information on fundamental molecular bond vibrations in a minimally perturbing and label-free manner, revealing specific molecular fingerprints which can be later used to identify the sample. Technological advances over the last decade have led to different Raman spectroscopy modalities using light to interrogate vibrations of the molecules on the surface or deeper inside samples of interest such as cells or tissues. In this talk, I will focus on deep Raman spectroscopy (spatially- offset and transmission modalities) and will elaborate on relevant biological applications such as storage lesion assessment in transfusion blood bags, cell therapy and cancer diagnostics.
