Nanopatterned Surfaces for Highly Selective Adhesion, Sensing and Separation
This technology provides novel, engineered surfaces containing nanoscale adhesive elements whose surface arrangements are optimized for highly selective adhesion, sensing and separation of biological or non-biological analyte particles in a broad range of sizes, from submicron to tens of microns. The nanopatterned surfaces are designed to exploit repulsive interactions between analyte particles and the main portion of the surface in addition to attractions between the adhesive elements and the target particles. The competitive attractive and repulsive interactions produce tunable selective dynamic adhesion for approaching particles, discriminating targets on the basis of size, local curvature (roughness), net charge density, and arrangement of surface functional groups.
Re-Usable, Self-Cleaning Surfaces: A portion of the parameter space for these surfaces produces weak net attractions between targets and the collector, such that the collecting surface spontaneously clears after an exposure, facilitating repeat uses.
