Use of a hollow fibre membrane in microdialysis

摘要

The present invention concerns a microdialysis device comprising a semipermeable hollow fiber membrane having the selective layer on the outer wall surface. The membrane has the smallest pore size on the outer wall surface, and has an outer wall surface which is smooth, continuous and homogeneous on a nanoscopic scale. It further comprises a number of distinct functional layers (1,2,3,4,5).
