Abstract
Methods of forming two-dimensional nanopatterns are provided. The method may comprise periodically contacting a vibrating tool comprising a patterned grating edge with a substrate along a first direction in a grating-vibrational indentation patterning process. The patterned grating edge defines a plurality of rows and a plurality of interspersed troughs. The periodic contacting creates a two dimensional array of discontinuous voids in a single-stroke across the surface of the substrate. In other aspects, a microfluidic device for selective arrangement of a microspecies or nanospecies is provided, that includes a substrate comprising a surface defining a two-dimensional pattern of microvoids or nanovoids. In yet other aspects, the present disclosure provides a method for selective arrangement of a microspecies or nanospecies on a substrate.
