Claim:
1. A device for transient contacting notably in vivo of an one unit for capturing biological targets with a body fluid containing said targets, said device comprising: a sampling tip having a contacting end configured to be introduced into a medium containing said fluid, and said capturing unit, which is bound to said contacting end and which comprises a capture substrate defining a target capturing surface covered with a biocompatible and porous crosslinked polymer layer configured to retain said capture substrate and only to allow biological particles including said targets smaller than a limiting size to pass through, in such a way that said capture substrate is recoverable after this contacting by dissolution of said polymer layer; wherein said capturing unit is connected to said contacting end of the tip via connecting means, which are fixed to said contacting end by welding or gluing, and said connecting means comprise a biocompatible porous bag which is fixed to said contacting end of the tip and which envelops said capturing unit, which contains particles that constitute said substrate and that are embedded in said polymer layer.
