“…Moreover, when comparing the performance of this sensor to previous reports utilizing fluorescence, colorimetric, and electrochemical devices, this hybrid sensor exhibited a LOD that was 1–3 orders of magnitude better. 164 Finally, the sensor exhibited excellent selectivity toward Pb 2+ wherein exposure to other metal ions such as Ag + , Ca 2+ , Cd 3+ , CO 2+ , Cu 2+ , Fe 3+ , Hg 2+ , K + , and Ni 2+ did not induce any evident change in fluorescence.…”

“…Due to these interactions, the Hg 2 + ions can be strongly absorbed on the surface of modified electrode by the coordination of the nitrogen atom in ERpNBA molecules with Hg 2 + ions through lone pair of electrons present on it [32,33]. Hence, the analytical performance of modified electrode was tested for different concentrations of Hg 2 + ions (lower concentration range - Figure 3B and higher concentration range - Figure 3C).…”

Pulse techniques in electron paramagnetic resonance (EPR) allow for a reduction in measurement times and increase in sensitivity but require the synthesis of paramagnetic probes with long relaxation times. Here it is shown that the recently synthesized phosphonated trityl radical possesses long relaxation times that are sensitive to probe the microenvironment, such as oxygenation and acidity of an aqueous solution. In principle, application of Fourier transform EPR (FT‐EPR) spectroscopy makes it possible to acquire the entire EPR spectrum of the trityl probe and assess these microenvironmental parameters within a few microseconds. The performed analysis of the FT‐EPR spectra takes into consideration oxygen‐, proton‐, buffer‐, and concentration‐induced contributions to the spectral shape, therefore enabling quantitative and discriminative assessment of pH, pO2, and concentrations of the probe and inorganic phosphate.
