New dual ionophore immunosensor concept modeling and experimental support [PDF]

, 2010
Literature shows that ion-selective electrodes (ISEs) can be modified to create a potentiometric immunoassay by covalent attachment of a hapten to the ionophore and use of immunocompetition to modulate transmembrane ion flux.

Rational Design of Crown Ether‐Based Fluorescent Sensors for Group II Cations: Insights From Vibrational Spectroscopy and Computation

ChemPhysChem, Volume 27, Issue 12, 26 June 2026.
We use vibrational spectroscopy to determine the solution phase structures of complexes of two fluorescent sensors with metal ions. We use these to understand differences in the absorption spectra and to explain why even very low levels of water destroy the fluorescent response. Rational design of fluorescent sensors requires knowledge of the molecular

Effects of Monensin, Calcareous Algae, and Essential Oils on Performance, Carcass Traits, and Methane Emissions Across Different Breeds of Feedlot-Finished Beef Cattle

Ruminants
With the growing use of crossbred cattle in Brazilian feedlots and increasing pressure to reduce antibiotic use as growth promoters, this study examines the impact of three feed additives—monensin (MON), monensin with Lithothamnium calcareum (LCM), and a
