Staining-free imaging methods are advantageous for revealing chemical information of biomedical materials. PiFM is a promising new spectroscopic imaging method, which combines excitation in the mid infrared by quantum cascade lasers with detection using a conductive AFM tip, thereby, enabling nanoscale lateral resolution. Here we present PiFM and discuss advantages and disadvantages compared to established IR- and Raman spectroscopy imaging methods.
