A development method for gold nanoparticles (GNPs), supported on nitrocellulose membrane by a simple contact between a GNPs solution was prepared with Tetra aurochloro acid (HAUCL4) solutions precursor. Nitrocellulose membranes are of particular interest in many bimolecular analyses, biosensors, cosmetic industries, especially for detection of specific proteins or peptides and nucleic acid sequences. These kinds of membrane currently suffer from insufficient detection sensitivity and low retention value for proteins less than 5 KDa. These deficiencies can be overcomed by constructing hierarchically structured separation layer on a porous membrane using GNPs colloidal solution. The surface modified membranes were able to effectively detect proteins less than 5 KDa than conventional membranes, since metals have high affinity towards protein. Activities of GNPs supported membrane were studied through western blot experiment and their performances were compared with the conventional membrane. The coated membrane performance increased which was proved by western blot experiment.
