Figure 2

Inverted fluorescence image (4× objective lens) of an OHSC, grown on an insert membrane, with a fused silica capillary positioned orthogonally, directly above the OHSC. A. No applied voltage at time 1) 0 s, 2) 6.6 s, and 3) 13.2 s. B. 3 kV applied, images taken at times 1) 0 s, 2) 6.6 s, and 3) 13.2 s. The Thioglo-1 injection capillary is outside of the field of view of these capillaries.
