Fig. 4
Temporal changes in secondary ion images of 12C- and 31P- of Target 2 acquired in PMo mode. The images were generated by dividing a total of 700 images into stacks of 140 images each, creating 5 temporal image series. Unlike Target 1, the counts of both 12C- and 31P- increase as the frame number increases. The numbers on the upper left side of each image indicate the stacked frames used to create those images. The cartoons depicted below the ion images are schematic diagrams illustrating scanning frames passing through the tuber structure of Target 2 during NanoSIMS analysis. Scale bars are 5 μm.
