This study reports the facile method for the deposition of gold nanoparticle thin film onto a monoporous semi-permeable cellulose membrane through the diffusion of borohydride ions leading to the reduction of AuCl4- ions. The synthesis of gold nanoparticle thin film was deposited on one side of the membrane that was exposed to AuCl4- ions while the other side containing a reducing agent remained clear. The gold nanoparticle thin film exhibited a broad Surface plasmon resonance (SPR) peak at 529 nm. Various characterization techniques were employed and all demonstrated the presence of gold thin film. The reported method represents a simplistic method for the deposition of gold nanoparticle thin films and various other metal nanoparticles may be deposited following this method.
