“…In addition, our trials showed that the AuNPs-attached GC interfaces can be used for electrochemical measurements with no problems, as some results have been already reported. 30 As a concluding remark, the present SEM images were obtained on unpolished GC surfaces to show changes in the surface images of AuNPs formed by the seed-mediated growth treatment. In contrast, in an electrochemical analysis, to polish the base electrode, i.e., GC surfaces, are quite normal and important to obtain reproducible responses.…”

A seed-mediated growth method for surface modification was applied to the attachment of gold nanoparticles (AuNPs) to glassy carbon (GC) surfaces. By simply immersing a GC plate at first into a seed solution containing 4 nm Au nano-seed particles and then into a growth solution containing HAuCl4, ascorbic acid and cetyltrimethyammonium bromide, AuNPs could be successfully attached to the GC surface via the growth of nanoparticles. A possible control of the size and density of AuNPs on GC was examined by observing surface images with a field-emission scanning electron microscope (FE-SEM) after several preparations with different immersion times. Compared with previous results on the growth of AuNPs on indium tin oxide (ITO) surfaces, it was characteristic that the AuNPs attached to GC surfaces exhibited smaller size and higher density as well as a flatter and non-crystal-like morphology. In addition, for performing the dense attachment of regular nano-sized AuNPs on GC surfaces, immersion for 2 h into the growth solution was sufficient. Longer immersion for 24 h caused an irregular growth of bold Au micro-crystals, while 24 h was necessary in the case of AuNPs on ITO surfaces. Shorter seeding and growth times were found to be effective for a sparse attachment of smaller Au nanoparticles whose size was ca. 20 nm. It was clarified that the seed-mediated growth method for surface modification was valid for fabricating a nanointerface composed of AuNPs on GC surfaces.

“…9,10 Another adverse effect is its reaction with amines and amides in the stomach producing high carcinogenic intestinal N-nitrosamine. [11][12][13] The current trends lead us to conclude that, there is a need of reliable, selective, sensitive and less expensive methods for the detection and quantification of the nitrite ion in environmental, food, industrial and physiological samples.…”

A rhodamine B-based fluorescent probe for nitrite ion (NO 2 − ) has been designed, synthesized, characterized and its properties for recognition of NO 2 − were studied. Nearly non fluorescent probe upon reaction with nitrite ion significantly triggered the fluorescence. Fluorescence response is based on ring opening of the spirolactam of rhodamine B phenyl hydrazide showing maximum absorbance at 552 nm and maximum emission at 584 nm. Probe 3 exhibited high sensitivity and extreme selectivity for nitrite ion over other common ions and oxidants (Cl − , ClO

“…In the first stage, nitrite ions are oxidized to NO 2 ; in the second stage, NO 2 is exposed to disproportionation reaction, resulting in NO 2 − and NO 3 − ions [6,7]. Some authors [8][9][10][11] think that acceleration of electrode processes on nanoelectrodes as compared with typical bulk electrodes is observed. Other studies [6,12] do not confirm the manifestation of nanoeffects in nitrite ions oxidation.…”

The purpose of this paper is to propose mathematical modeling of different kinds of electrochemical processes. Electrooxidation of nitrite ions on some types of electrodes (glassy carbon, screen-printed carbon-containing, gold, and gold nanoparticles) and oxidation of ascorbic acid on gold electrodes nonmodified and modified by gold nanoparticles were used for the comparison of calculated and experimental data. It is shown that in each case, a specific shape of the voltammogram helps to identify the mechanism of the process. The comparison of the theoretical and experimental data shows that the process of oxidation of nitrite ions causes passivation of the electrode by adsorbed products of electrooxidation, and nanoeffects are not observed at that. Nanoeffects were observed in the oxidation of ascorbic acid on gold nanoparticles localized on gold electrode.
