The metal nanostructures have attracted much research attention because of their unique opto-electrical properties such as surface Plasmon resonance (SPR) and surface enhanced Raman scattering (SERS). Their unique properties were successfully controlled by tailoring their structures and harnessed to devise highly sensitive biosensor and imaging tool. Therefore, it is one of the important issues that the development of an appropriate synthetic strategy of metal nanostructures with structural diversity. In this study, we have developed a strategy for the direct growth of Ag nanoplates on a solid substrate by using seed-mediated growth approach. The synthesized Ag nanoplates were further grown by simply repeating seed-mediated growth under the same synthetic condition. Based on the present strategy, the size and surface density of grown Ag nanoplates were increased with repeated growth, thus, the SPR band of synthesized Ag nanoplate grown substrates was changed according to their structural development during repeated successive growth cycles. The resulting Ag nanoplate grown substrates showed excellent performance as a SERS platform. We believe that the present strategy will be an important addition to the fabrication of SERS-based sensing platform with high sensitivity and reproducibility because of cost-effectiveness and simple fabrication processes with exellent performance.
