In this work, Ag nanoparticles (NPs) were deposited on patterned TiO2 nanotube films through pulse-current (PC) electrodeposition, and as a result patterned Ag NPs films were achieved. Scanning electron microscopy (SEM), electron probe microanalysis (EPMA), and X-ray diffraction (XRD) were used, respectively, to study the morphology, uniformity, and phase structure of the patterned Ag NP films. The size and density of the as-deposited Ag NPs could be controlled by changing the deposition charge density, and it was found that the patterned Ag NP films produced under a charge density of 2.0 C cm(-2) gave intense UV-vis and Raman peaks. Two-dimensional surface-enhanced Raman scattering (SERS) mapping of rhodamine 6G (R6G) on the patterned Ag NP films demonstrated a high-throughput, localized molecular adsorption and micropatterned SERS effect.
