Abstract

Detection of volatile organic components (VOCs) is meaningful to agricultural field, bio recognition and so on. In this study, we developed an array type gas sensor to detect VOCs. This sensor is based on localized surface plasmon resonance (LSPR). Molecularly Imprinted Sol-Gels (MISG) were patterned on the surface of Au nano-islands to add molecular selectivity. The substrate is separated into 9 regions on AuNPs by using polyimide tape partitions and spin coating MISG solutions for each region. Multi channels sensor was fabricated with this substrate after this process. The sensor's sensitives were compared for each channel. The result indicated that the sensitivity of target gas channel was higher than into others.
