To show the feasibility of cryo-correlative imaging in food oxidation studies, the dilute emulsions were prepared on either a Finder/Au or a Copper/Quantifoil TEM grid. We first measured the fluorescence images of emulsions using BODIPY 665/676 in cryo-FM before imaging the same droplets in cryo-TEM. With the Finder/Au TEM grid, the droplets could be easily tracked based on the letter markers (Fig. ). With the Copper/Quantifoil TEM grid, a damaged artifact was intentionally made with high laser power (1700 W/cm 2 at 638 nm excitation) on the grid (Fig. ). This approach enables tracking in cryo-TEM together with the asymmetric centre mark of the TEM grid (Fig. ). Again, this method was used to correlate the same oil droplets in cryo-FM and cryo-TEM. We confirmed that both methods are applicable for finding the same position in cryo-FM and cryo-TEM. The markers on the Copper/Quantifoil TEM grid were made with the illumination at 1700 W/cm 2 of 638 nm excitation for 1 min (i). Employing either marker approach, the same droplets could be co-localised in cryo-FM (ii) and cryo-TEM (iii).
