Localized Surface Plasmon Resonance Sensor Based on Fabricating Nano-period Structure for High Throughput by Polymer

Abstract

To realize a low-cost sensor and a sensor chip, we propose a localized surface plasmon resonance (LSPR) sensor in which nano-imprinting technology is applied to produce periodic arrangements of metallic nanostructures; we also verify its utility. LSPR can concentrate electric fields in the vicinity of nano-order metal structures. Accordingly, the sensing depth can be localized, resulting in noise reduction. Furthermore, nano-imprinting can be applied inexpensively and with high accuracy to fabricate nano-patterned sensor chips in large quantities. This work involves the design of an original nano-period structure and the application of nano-imprint technology to the fabrication of a sensor chip. The result is a proposal for a biosensor that allows fabrication with both higher throughput and lower cost.
