Abstract

The detection of cis-jasmone is meaningful to sense potential threat in agriculture. In present study, a nanocomposite imprinted LSPR sensor was developed for determination of cis-jasmone vapors. Molecular imprinted sol-gels (MISG) were fabricated on the surface of Au nano-islands via spinning coating. For enhancing the sensitives of sensors, AuNPs was sputtered on the MISG layers. The sensitives and selectivelies of samples recoated divers thickness of AuNPs were compared and discussed. The result indicated that the sensitivity of AuNPs/MISG/AuNPs was higher than that of AuNPs/MISG. In addition, AuNPs/MISG coated with 3 nm AuNPs shown a better sensitive and selectively. In-situ response was verified to be fast, selective and reversible. The absorbance spectra of cis-jasmone vapors linearly increased with its concentration in the range of 10 to 75 ppm, with the limit of detection of 3.45 ppm (S/N=3). The research offered useful technologies for developing cis-jasmone sensor in agriculture area.
