SPATIALLY INHOMOGENOUSLY FUNCTIONALIZED POROUS MEDIA AND METHOD FOR USE IN SELECTIVE REMOVAL OF CONTAMINANTS

摘要

Compositions and methods for separating double-stranded nucleic acids out of a mixture comprising single-stranded nucleic acids and/or dNTPs and/or enzymes. The method uses spatially inhomogeneously functionalized nanoporous materials. For example, the compositions and methods of the present invention can be used to purify DNA amplification reaction products.
