Nanowell‐Array Surfaces

Abstract

Well-designed surfaces: A method of chemical information storage was realized with an ordered array of nanowells that were plasma-etched into a glass surface. Modification of the surface through the application of a Au/Pd coating and the chemisorption of 1-octadecanethiol allows spherical polystyrene nanoparticles of appropriate charge to be stored within the nanowells but not on the surrounding surfaces (see AFM image).
