Metal ion patterns: Patterns of metal ions on glass slides coated with fluorescent self-assembled monolayers (SAMs) are fabricated. Different degrees of fluorescence enhancement occur with different metal ions (see schematic). The use of an atomic force fluorescence microscope (AFFM) and the sensing properties of the fluorescent SAMs, permit writing and the immediate visualization of submicrometer-scale metal-ion patterns on glass.
