Nanoporous Aluminium Oxide Membranes as Cell Interfaces
SEM images of a nanoporous AAO membrane following deposition of 8 nm zinc oxide. Cross-sectional micrographs obtained from (a) 200 nm pore diameters, (b) the middle of the pore (~100 nm), and (c) the small pore side (20 nm) of a cleaved specimen show a continuous zinc oxide coating. Plan-view scanning electron micrographs obtained from (d) the 200 nm pore side and (e) the small pore side of the membrane (20 nm) also show a continuous zinc oxide coating .
