Since 1997 our groups are involved in  applications of gamma radiation to obtain advanced polymeric materials. This work is done by  the implementiation of different grafting thecniques into polymers, potentially usefull for biotechnological process. In this way the following materials have been developed: (a) polysulfone and polyethersulfone membranes whit specific protein-adsorptive properties; (b) polyethylene adsorptive membranes grafted by molecular   imprinting; (c) hydrogel supported onto sintherized HDPE for bacteria inmobilization applied to bio-catalysis process; (d) porous polymethacrylate solids for analytical separation process; (e) hydrogels confined into macroporous membranes to develop an extracorporeal bioartificial liver and (f) modified nanoporous track-etched membrane.
