Inkjet printing technique is a versatile tool as it enables the optimization of the materials and the placement of picoliter volumes of materials in accurate locations over the substrate surface at a minimum cost and virtually without environmental hazard footprint. In this project, we will demonstrate inkjet printing as a versatile and robust enabling technology to prepare surface-enhanced Raman scattering (SERS) substrates by tuning surface plasmon resonance and photonic band gap, respectively. The project comprises of several challenges as follows: (1) Synthesis of noble metal nanoparticles and stable dispersions of those to be applied as inks; (2) Synthesis of monodispersed submicron spheres and their derivatives by decorating the colloidal spheres with metal nanoparticles to achieve photonic structures with combined surface-enhanced Raman scattering effect; and (3) the demonstration of enhanced Raman-scattering from e.g. soft matter, gas and biomolecules. By developing the inkjet printing techniques, we expect that this project will lead to the exploitation of environmentally friendly aqueous inks in SERS substrate applications with performance as good as or better than their conventional competitors with much lower environmental footprint and reasonable cost factor.表面電漿共振表面電漿增強拉曼散射奈米粒子。Surface plasmon resonanceSurface-enhanced Raman scatteringnanoparticles.
