Directional movement of dendritic macromolecules on gradient surfaces.

摘要: A gradient-driven methodology has been developed to manipulate the movement of dendritic macromolecules. Poly(propyleneimine) dendrimers, labeled with rhodamine B, are attached glass substrates via multiple imine bonds. The dendrimers able move on surface by hydrolysis and re-formation these In absence an external stimulus, this random results in a two-dimensional diffusion substrate. We bias nanoparticles means aldehyde gradient
