Abstract (en)

[origin: WO0161042A2] Disclosed are smooth surfaced porous membranes having one or more advantages such as low autofluorescence, thermal-cyclability, especially under humid conditions, and three-dimensional binding capacity. The membrane can be free-standing or, preferably in combination with a support as in a composite membrane. The present invention provides a composite membrane comprising a porous polymer layer disposed on a support. The present invention further provides devices such as microarray devices comprising the composite for the analysis of biomaterials such as nucleic acids.
