Fig. 3. Newly designed specially-shaped capillaries improve the detection of free radicals in living zebrafish embryos. Schematic view of the capillaries (A, B) and photograph (A′, B′) of a standard 100 μL hematocrit capillary (A, A′) and the prototype of the specially-shaped capillary (B, B′). Cw-EPR signal from 10 μM 3-CP probe recorded with eSpect+: C. standard 100 μL capillary, signal-to-noise = 23, and D. specially-shaped flat capillary, signal-to-noise = 18. The signal form glass impurities is marked with an asterisk (*). EPR parameters were 20dB/MA-500μT/ST-11s/16sc.
