Figure 3

(a) An SEM image of the specific length of membrane wall along which fluorescence microscopy characterization was conducted. 1, 2, and 3 indicate the locations in the CNF membrane wall from which 50 nm beads emerge; high-resolution SEM image insets show the exit surface nanopore morphologies. (c) The CNFs were coated with a conformal coating of oxide to reduce the size-selective property of the CNF membrane barrier to the size range of 50–100 nm. This image was collected following fluorescence experiments; the PDMS lid was delaminated to take the SEM image and PDMS residue is evident at the sealing tips of the oxCNFs.
