TL;DR: Cryptand and its charge transfer complex with iodine was used as an indicator electrode in potentiometric titration of copper in ore samples as discussed by the authors, where the response times (t95%) of the sensors were 10 and 5 s.

TL;DR: In this paper, several new mechanisms and structures are used simultaneously, including a SEF-based metal nanoparticle–organic dye hybrid, dual signal amplification in a two-dimensional probe between the GNP–thionine hybrid and MNPs, and a novel releasing method using protease enzymes, which improve the sensitivity and speed, along with the simplicity of the procedure.

TL;DR: In this paper, a new electrochemical sensor for hydrogen peroxide (H2O2) determination was fabricated based on less expensive and simple layer-by-layer method, where the morphological and elemental characteristics of palladium, copper and titanium oxide nanoparticles modified glassy carbon electrode (GCE) were examined using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX), respectively.

TL;DR: Co3O4 NPs in N-doped porous carbon were prepared by one-pot pyrolysis of a ZIF-67 powder under N2 atmosphere and followed by oxidation under air atmosphere (200 °C) toward promotion catalytic activity and activation of peroxymonosulfate (PMS) to degradation sulfamethoxazole (SMZ) as discussed by the authors .

TL;DR: In this article, a glassy carbon electrode with uniform worm-like cobalt oxide nanostructures (CoOx-NSt) was used as a novel amperometric sensor for guanine determination in the nanomolar-micromolar concentration range.
