Methods for separating one or more analytes present in a fluid sample by passing the fluid through or into a mioroporous material (100), wherein the analytes are localized near the surface of the microporous material. Microporous material (100) has planar surface (120) and external surface (130) have holes or pores (110) therethrough. An internal surafce (140) is formed by channel (150). The analyte localizes: (i) in the region (160) 10 microns below the planar surface (120), (ii) adjacent to the planar surface (120), or (iii) in theregion (170) 25 microns above the planar surface. |
