    Thymine-Functionalized Gold Nanoparticles (Au NPs) for a Highly Sensitive Fiber-Optic Surface Plasmon Resonance Mercury Ion Nanosensor by Huizhen Yuan, Guangyi Sun, Wei Peng, Wei Ji, Shuwen Chu, Qiang Liu, Yuzhang Liang

    Published 2021-02-01
    “…In the presence of Hg<sup>2+</sup> ions, the immobilized thymine combines specifically with Hg<sup>2+</sup> ions, and forms an Au/thymine-Hg<sup>2+</sup>-thymine/Au (Au/T-Hg<sup>2+</sup>-T/Au) complex structure, leading to a shift in SPR wavelength due to the strong electromagnetic couple between Au NPs and Au film. Under optimal conditions, the proposed sensor was found to be highly sensitive to Hg<sup>2+</sup> in the range of 80 nM–20 µM and the limit of detection (LOD) for Hg<sup>2+</sup> was as low as 9.98 nM. …”

    Published 2021-07-01
    “…Increasing pulse voltage range and frequency and compactness are important issues that should be taking into consideration.Methods: The high voltage pulse generators which are introduced in the literature have some disadvantages and complexities such as need of additional winding to reset the transformer core and operating under hard switching which increases electromagnetic noise and loss. The leakage inductance of the high voltage transformer increases the rise time of the pulse which is undesirable for DBD applications. …”
