Nanoporous Aluminium Oxide Membranes as Cell Interfaces
Images of growth compartments and microbial culture on AAO chips. (a) SEM of aluminium oxide showing pores on average 200 nm diameter. (b) Transmission light microscopy of hundreds of μm2 compartments viewed from above. (c) SEM image of μm2 compartments from above at a 30° angle. (d) Culture of L. plantarum in six compartments of the same dimensions as (c), stained with the fluorogenic dye Syto 9 after growth and imaged from above .
