Figure 3: Micrographs with cross-sections of AOT myelin growth in water, later freeze-dried after plunging in liquid nitrogen and observed under SEM. Surface of the specimen was treated by a vacuum deposition of gold. (a) Lateral view of elongated tubular AOT myelin figures bundled with tip region after cutting with a cold knife. (b) A cross-sectional view of AOT myelin figures showing no detailed internal microstructures indicated by arrow. The white bar in the micrographs represents 10 μm.
