“…In previous work, we demonstrated that derived gold NPs on 1D ZnO supports were produced via self-assembly of gold salt precursors and subsequent local reduction of AuCl 4 − ions, which are ion-paired with protonated 3-aminopropyltriethoxysilane (APTES) that are chemically attached to rich-hydroxyl surface of ZnOnanorods [16,17]. Herein, we further extended our study for the synthesis of 1D…”

Alcohol detection plays a key role in food processing and monitoring. Therefore, we present a fast, high reproducibility and label-free characteristics alcohol photochemical sensor based on the surface plasmon resonance (SPR) effect. By growing ZnO nanoflowers on Au film, the SPR signal red-shifted in the visible region as the alcohol concentration increased. More interestingly, the sensitivity improved to 127 nm/%, which is attributed to the ZnO nanoflowers/Au structure. The goodness of the linear fit was more than 0.99 at a range from 0 vol% to 95 vol% which ensures detection resolution. Finally, a practical application for distinguishing five kinds of alcoholic drinks has been demonstrated. The excellent sensing characteristics also indicate the potential of the device for applications in the direction of food processing and monitoring, and the simple structure fabrication and economic environmental protection make it more attractive.

“…), which was prepared by mixing of 2 % APTES with 93 % of ethanol and 5 % of DIW. The silanyl group (-SH 3 ) presented in APTES was used for the process of silanization, the chemically attached with the hydroxyl-rich ZnO NRs (Hou et al 2012). On the other hand, amino group (NH 2 -) presented in APTES was served as a glue layer to attached the GNPs which linked to probe DNA.…”
