Surfaces with two-dimensional nanoring or nanoporous arrays and nanopatterned SAMs have been fabricated via the “colloidal crystal-assisted capillary nanofabrication” (CCACN) method. The Figure shows the two-dimensional poly(vinyl alcohol) (PVA) nanoring arrays generated using a delicate template and the controllable capillary and dewetting actions in the CCACN process.
