TL;DR: Addition of anionic surfactant, sodium dodecylsulfate (SDS) and cationic surfactants, cetyltrimethylammonium bromide (CTAB) to the demeclocycline-containing electrolyte solution at pH 2.0 and 9.0, respectively, was found to improve the sensitivity of the stripping voltammetric measurements.

TL;DR: In this paper, a semicarbazide-based naphthalimide was designed and synthesized as a colorimetric fluorescent probe, which exhibits color changes from colorless to jade green accompanying remarkable enhancement in its fluorescence.
Abstract: A semicarbazide-based naphthalimide was designed and synthesized as a colorimetric fluorescent probe. Upon reaction with Cu2+ in a buffer solution of pH 7.4 (buffer water/acetonitrile = 80:20, v/v), the probe exhibits color changes from colorless to jade-green accompanying remarkable enhancement in its fluorescence, which could be mechanistically ascribed to the Cu2+-promoted hydrolysis of the semicarbazide moiety leading to the release of the green fluorescent 4-amino-1,8-naphthalimide fluorophore. The probe also displayed excellent performance in high sensitivity as well as good selectivity for Cu2+ over other metallic cations.

TL;DR: In this paper, a carbon nanoparticle-chitosan host film was used to immobilize PdCl2 as a catalyst precursor, and high activity for formic acid oxidation was observed in aqueous phosphate buffer medium.
