Process for forming a polymer layer with a uniform thickness on the surface of a solid support, solid support obtained and its applications

Abstract

The present invention relates to a process for forming a polymer layer with a uniform thickness on the surface of a solid support, to the solid support obtained using this process, and to its applications.

1 . A process for forming a polymeric layer with a uniform thickness on at least part of one of the surfaces of a solid support, wherein said polymeric layer is obtained by copolymerization of a monomer solution containing monomers carrying a functional group capable of stopping the copolymerization reaction, and in which solution the amount of monomers carrying said functional group represents at least 50% of the total amount of monomers present within said solution.  
     
     
         2 . The process as claimed in  claim 1 , wherein the amount of monomers carrying said functional group represents at least 60% of the total amount of monomers present in said solution.  
     
     
         3 . The process as claimed in  claim 2 , wherein the amount of monomers carrying said functional group represents from 60 to 95% of the total amount of monomers present in said solution.  
     
     
         4 . The process as claimed in any one of the preceding claims, wherein the monomers are chosen from pyrroles, anilines, thiophenes and azulenes.  
     
     
         5 . The process as claimed in  claim 4 , wherein the monomers are chosen from pyrroles and the copolymerization reaction is an electropolymerization reaction.  
     
     
         6 . The process as claimed in any one of the preceding claims, wherein the functional groups capable of stopping the copolymerization reaction are chosen from aldehyde, nitrile, ester, alkyl and aryl functional groups.  
     
     
         7 . A solid support, which is obtained using the process as defined in any one of  claims 1  to  6 .  
     
     
         8 . The use of at least one solid support as defined in  claim 7  for isolating, separating and/or analyzing biological and biochemical elements.  
     
     
         9 . The use of at least one solid support as defined in  claim 7  for producing biological chips.
