Claim 10:
11. A device for extracting a molecule of interest from a sample matrix, the device comprising:
a support comprising a support surface, and comprising an insertion end and a mounting end;
a sealing layer that at least partially coats the support surface from the insertion end towards the mounting end leaving a portion of the support surface uncoated at the mounting end, wherein the sealing layer consists of a layer of polyacrylonitrile (PAN); and
an extractive phase coating applied to a portion of the sealing layer leaving a portion of only the sealing layer extending past the end of the extractive phase coating, allowing the coating to be fully immersed in the sample matrix while preventing the uncoated stainless-steel support surface from coming in contact with the sample matrix, wherein the extractive phase coating is adapted to contain the molecule of interest.
