The invention provides methods for the treatment of surfaces using surface adsorbing polymers, methods for decreasing the adsorption of organic materials onto the surface of treated devices or vessels, methods for performing fluid operations involving the treatment of surfaces, and apparatus and systems comprising the treated surfaces. Further, the present invention provides a method for treating the surface of microfluidics channel wherein the microfluidics surface is coated for deactivation and wherein this coating can be easily regenerated. The present invention also provides a method for treating the surface of a plastic device. The surface adsorbing polymers of the invention are particularly stable at temperatures and conditions required for biochemical reactions, especially in applications involving temperature cycling or polymerization of polynucleotides or polypeptides.

L'invention concerne des procédés de traitement de surfaces utilisant des polymères d'adsorption en surface, des procédés de diminution de l'adsorption de matières organiques sur la surface de dispositifs ou de récipients traités, des procédés d'exécution d'opérations sur des fluides consistant en un traitement de surfaces et un appareil ainsi que des systèmes contenant les surfaces traitées. De plus, la présente invention concerne un procédé de traitement de la surface d'un canal microfluidique dans lequel la surface microfluidique est revêtue afin d'obtenir une désactivation et dans lequel ce revêtement peut être régénéré facilement. La présente invention concerne également un procédé de traitement de la surface d'un dispositif en plastique. Les polymères d'adsorption de surface de l'invention sont particulièrement stables à des températures et dans des conditions nécessaires aux réactions biochimiques notamment dans des applications faisant intervenir des cycles de températures ou une polymérisation de polynucléotides ou de polypeptides.
