Abstract

The invention concerns a Biodetector with a functionalised surface for isolating molecules or cells from the human body. In order to improve a Biodetector of the type mentioned above such that the functionalised surface of the Biodetector or there upon enriched molecules or cells are exposed to a lower abrasion, and the biocompatibility of the Biodetector is improved, the Biodetector is designed to remove a fluid from the human body and absorb it into an inner space of the Biodetector, wherein the functionalised surface is oriented to the inner space of the Biodetector.
