Controlled Gold Nanoparticle Synthesis Using H-bonded Polyelectrolyte Multilayer Films as Templates |
| 초록 |
The optical properties of gold nanoparticles (AuNPs) are of great interest for nano-scale science and practical sensing applications. The fabrication of three-dimensional arrays of AuNPs 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 also have the potential for sensor applications. We have synthesized gold nanoparticles using polymeric thin films as templates and studied the SPR spectroscopy of the hybrid system. Polymeric thin films were fabricated by layer-by-layer process using weak polyelectrolytes driven by electrostatic and hydrogen bonding. AuNP syntheses on various PEM films were conducted and cellular interactions on the PEM films were also studied with various cell types. |
