High chemical specificity may be achieved by directly interrogating the fundamental or low-lying vibrational energy levels of the compound molecules. Amongst the available prevailing label-free techniques, coherent Raman scattering has the distinguishing features of high spatial resolution down to 200 nm and three-dimensional sectioning. However, combining fast imaging speed and identification of multiple - and possibly unexpected- comp","authors_text":"Birgitta Bernhardt, Guy Guelachvili, Nathalie Picqu\\'e, Simon Holzner, Takuro Ideguchi, Theodor W.
