Fig. 2 (IMAGE) Osaka University Caption Schematic of the sample area in the developed cryo-Raman microscope. A cover glass with cultured cells is placed on the sample mount, and a metal plate is brought into contact (left). The cryogen enters through the inlet and a hole in the metal plate, coming into direct contact with the sample for rapid freezing. The sample temperature is controlled by the metal plate with liquid nitrogen circulation and a heater inside (right). Credit Sci.
