Through the LbL technique, we fabricated hybrid films using Gold Nanoparticles(AuNP) and Polyelectolytes. We used unusual goldnanoparticle which is controlled shape and surface functional group. Gold has many poperties, especially the optical properties of AuNP are great interest for nano-scale science and practical sensing applications. The fabrication of three-dimensional arrays of AuNP on flat substrates or thin films can be employed to tune and manipulate their optical properties. This also allows for characterization using surface sensitive spectroscopic and microscopic analytical methods. Because the excitation of surface plasmon resonance(SPR) at the surface can largely enhance the local optical field, they have the potential for sensor applications. Patterning is used to confirm potential of biosensor application. First of all, we studied to find better condition of AuNP which was concentration and pH. We try to detect bio-molecule using SPR measurement and stamp patterning. |
