Dynamic Surfaces and Directional Nanoscale MotionTao Ye, School of Natural Sciences, University of California Merced AFM image of aminoundecanethiol (squares) nanografted in a matrix of octadecanethiol. Spatial resolution as good as 10 nm has been achieved. Cyclic voltammogram of ferrocene thiol SAM. Upon oxidation, the SAM becomes positively charged. However, the ferrocenium groups undergo partial decomposition within 10 min. Patterned electroactive surfaces Reversible boronate formation between 1 and substituted catechols in MeOH. Upon binding the fluorescence intensity of 1 is reduced. The reversible oxidation of catechol to o-benzoquinone is also shown. (Lu et al., Chemical Communications 2009, 5491-5495.) Nanostructures with tunable chemical functionality Next step: integration AFM image of disc like GaSe nanoparticles deposited on Au(111). The particles are oriented and their aggregate states can be controlled by the surface ligands. Shao et al.,submitted.
