Ion-selective Imaging by Atomic Force Microscopy with a Crown-ether-modified Tip

Ion-selective surface imaging was successfully attained by atomic force microscopy with a probe tip functionalized with a 15-crown-5 derivative. The frictional force images for nanopatterned substrates revealed enhanced contrasts attributable to the cation-binding interaction between the 15-crown-5...

Description
Summary:Ion-selective surface imaging was successfully attained by atomic force microscopy with a probe tip functionalized with a 15-crown-5 derivative. The frictional force images for nanopatterned substrates revealed enhanced contrasts attributable to the cation-binding interaction between the 15-crown-5 on the tip and potassium ions on the substrate.
