Nanoparticle-Textured Surfaces for Highly Selective Adhesion, Sensing and Separation
This technology provides novel, engineered surfaces containing functionalized nanoparticle adhesive elements whose surface arrangements are optimized for highly selective adhesion, sensing and separation of biological or nonbiological analyte particles in a broad range of sizes, from submicron to tens of microns. The nanoparticle- textured 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 analyte particles, discriminating targets on the basis of size, local curvature (roughness), net charge density, and arrangement of surface functional groups.
