Abstract: The present invention is concerned with materials and methods for mediating eukaryotic cell attachment to rigid surfaces. In particular, the invention is concerned with coatings for forming cell attachment surfaces, preferably for cell culture devices, microfluidic devices, biosensors or implants. The invention correspondingly provides polymer conjugates for such coatings, methods of polymer conjugate formation, methods of polymer conjugate application and uses of such polymer conjugates. The invention also provides surfaces and devices at least partly coated with such polymer conjugates.

Abstract: The present invention relates to a biocompatible device which comprises on its surface an adsorbed layer of a polymer P which is a copolymer of at least one macromonomer selected from an ester E of (meth)acrylic acid and polyethylene oxide or a polyethylene glycol (meth)acrylamide, at least one monomer M selected from alkyl (meth)acrylate, aryloxyalkyl (meth)acrylate, alkyl (meth)acrylamide or aryl (meth)acrylamide, and at least one cationic monomer C selected from cationic ethylenically unsaturated N-containing monomers. It further relates to a process for making a biocompatible device which comprises on its surface an adsorbed layer of the polymer P comprising the following steps: providing a biocompatible device, and applying to the surface of the biocompatible device a solution S of the polymer Pin a solvent L.

Abstract: The present invention relates to a polymer comprising repeating units derived from at least one first monomer (monomer A) which is a molecule comprising a thiolactone ring and an ethylenically unsaturated, polymerizable double bond, and at least one second monomer (monomer B) which is N-vinyl pyrrolidone. Furthermore the present invention relates to a modified polymer, the structure of which is identical to the structure of the said polymer apart from the only difference, which is that all or at least some of the thiolactone moieties of the said polymer are modified by opening the thiolactone ring with a substance selected from the group consisting of ammonia, a primary amine, 2-amino-1-ethanol and L-lysine, wherein the N-atom of said substance is binding to the carbonyl group of the opened thiolactone ring. Furthermore, the present invention relates to a process for making the modified polymer and to the use of the polymer or of the modified polymer for treating hair.
