DEVICE OF SAMPLING AND ANALYSING BIOLOGICAL OR BIOCHEMICAL SPECIES

摘要

A method of sampling biological or biochemical species, comprising the following steps: a) arranging a capture surface (SC) for said biological or biochemical species in contact with a biological tissue or fluid (TB); and b) rinsing said surface to remove biological or biochemical species that have not been adsorbed; the method being characterised in that said capture surface is the surface of a nanoporous material (MC). A method of analysing said biological or biochemical species, characterised by the use of said surface as an analysis support. The analysis may in particular be performed using a method selected from mass spectroscopy with laser desorption and fluorescence imaging. A device for sampling biological or biochemical species comprising a rod (TM) to which is attached a material (MC) having a capture surface (SC) for said biological or biochemical species, arranged so as to be able to be brought into contact with a biological tissue or fluid (TB), characterised in that said material is a nanoporous material. The rod can be slid into a guide tube to facilitate the insertion thereof into a human or animal body.
