A) SEM images of the CNT growth with the final process before the sealing of the cover plate: (a) with a 20 nm nickel film, (b) with a 50 nm nickel film, and (c) with a 100 nm nickel film. B) HPLC analysis of the reversed phase test mixture (uracil, phenol, N,N-diethyl-m-toluamide, toluene), isocratic eluent water:acetonitrile (80:20), at a flow rate of 700 nL·min−1 with a UV detection at 254 nm (a) on the reference column (C18 reversed phase coating) and (b) on the CNT column.
