Resumen:
A polyelectrolyte-surfactant complex, polyallylamine-dodecylsulfate system, is presented as an alternative method for the modification of membranes. Due its chemical structure, the complex, once casted on a surface, is highly stable in aqueous solutions. This allows modifying with the same method different types of membranes, exemplified here by alumina and polycarbonate. Using different strategies, the complex system can also incorporate other elements useful for catalysis, biorecognition, or separation. Two applications are presented: the incorporation of gold nanoparticles to catalyze the reduction of 4-nitrophenol using a polycarbonate membrane, and the modification of alumina with a biotin derivative for the recognition of avidin in label-free sensors.
