In this study, a shear horizontal mode surface acoustic wave (SH-SAW) sensor, was designed and fabricated for the detection of heavy metals. The SH-SAW sensor was photolithographically fabricated by patterning gold (Au) interdigitated electrodes (IDE) and reflectors on the surface of a 64° YX-LiNbO 3 based piezoelectric substrate. A flow cell, with a reservoir volume of 3 µl, which employs inlet and outlet ports for the microfluidic chamber and polydimethylsiloxane (PDMS) based microfluidic channels, was also designed and fabricated using acrylic material. Phenol and naphtho[2,3-a]dipyrido[3,2-h:2'3'-f] phenazine-5,18-dione (QDPPZ) were employed as the sensing layers for mercury and nickel ions, respectively. The frequency based response of the SH-SAW sensor demonstrated picomolar level detection for mercury nitrate (Hg(NO 3 ) 2 ) and nickel nitrate (Ni(NO 3 ) 2 ).

“…[51] Chiral ferrocenylboronic acids have been reported for chiral electroanalysis. [23] Boronic acid moieties that are linked to other redox probes, such as Fe‐bipyridyl complexes,[52] phenazines,[53] or tetrathiafulvalenes,[18c] have been reported. In some cases, the analyte itself can act as the redox probe, for example, for catechols when bound to phenylboronic acid.…”

Synthetic receptors for diols that incorporate boronic acid motifs have been developed as new sensors and separation tools. Utilizing the reversible interactions of diols with boronic acids to form boronic esters under new binding regimes has provided new hydrogel constructs that have found use as dye-displacement sensors and electrophoretic separation tools; similarly, molecular boronic-acid-containing chemosensors were constructed that offer applications in the sensing of diols. This review provides a somewhat-personal perspective of developments in boronic-acid-mediated sensing and separation, placed in the context of the seminal works of others in the area, as well as offering a concise summary of the contributions of the co-authors in the area.

“…1,10-Phenanthroline based compounds are well-known for their effectiveness in binding with metal ions to form inorganic complexes [14][15][16][17][18][19][20][21][22][23][24]. However, the use of their derivatives in the detection of metal ions and other molecular substrates, are not well explored [25][26][27]. Naphtho[2,3-a]dipyrido[3,2-h:2',3'-f]phenazine-5,18-dione (QDPPZ), the derivative of 1,10-Phenanthroline could be used as a selective layer for heavy metal detection.…”

Abstract-A flexible electrochemical sensor was screen printed on polyethylene terephthalate (PET). Carbon and silver based inks were used for metallization of the working, counter and reference electrodes. 1,10-phenanthroline and its derivative naphtho[2,3-a]dipyrido[3,2-h:2',3'-f]phenazine-5,18-dione (QDPPZ) was synthesized as sensitive layers for Hg 2+ and Pb 2+ , respectively. Cyclic voltammetry response of the sensor resulted in reduction peaks at 0.2 eV and -0.6 eV for selective detection of Hg 2+ and Pb 2+ , respectively. An 87 % and 9 % change in the average peak currents were observed for the 50 µM concentration of Pb 2+ and Hg 2+ , respectively, against a reference signal established for deionized water (DI). The response of the electrochemical sensor demonstrated the use of traditional printing processes and synthesized chemicals for the selective detection of heavy metal ions.
