Summary of the ESR microimaging results for the live-cells sample shown in Fig. 4
| Slice position [μm] | T2 [ns] | O2 [μM] |
|---|---|---|
| Z = 0, 100, 200 (light off) | 470 ± 18 | 255 ± 10 |
| Z = 0 (light on) | 329 ± 24 | 394 ± 34 |
| Z = 100 (light on) | 342 ± 16 | 376 ± 18 |
| Z = 200 (light on) | 352 ± 18 | 364 ± 22 |
The numbers represent the mean and standard deviation results for each slice. The data representing the dark condition has a relatively small spread, both in-plane and between slices. The data for the light condition shows pronounced differences with respect to the dark condition and also considerable gradients of O2 from slice to slice. The in-plane variations are also quite large under light conditions, especially in the lower slice where most of the cyanobacteria are located.
