Ionophore-Based Optical Sensors
Annual Review of Analytical Chemistry, 2014This review provides an overview of the key aspects of designing ionophore-based optical sensors (IBOS). Exact response functions are developed and compared with a simplified, generalized equation. We also provide a brief introduction into less established but promising working principles, namely dynamic response and exhaustive exchange. Absorbance and

Ionophore Toxicity and Tolerance
Veterinary Clinics of North America: Food Animal Practice, 2011The rapid growth of the biofuels industry in the Midwest in the past 10 years has created an increased supply of corn coproduct feed for animals. This article discusses the tolerance and toxicology of biofuels coproducts in ruminants, including polioencephalomalacia, sulfur toxicosis, sulfur metabolism, mycotoxins, antibiotic residue, and biodiesel by ...

Turning Ionophores into Chromo- and Fluoro-Ionophores
2006This chapter concerns the use of selective, calixarene-based ligands for optical signalling in chemical analysis [1]. Although chromophoric ligands of many types are wellknown, calixarenes provide a number of novel and useful examples. Exploitation via optical sensing of the recognition of both ions and neutral molecules by macrocycles in general is ...

International Journal of Quantum Chemistry, 1981
AbstractThe present state in the chemistry of peptides and proteins capable of transporting ions across biological and model membranes have been reviewed. The mechanisms of action of peptide ionophores valinomycin and enniatin and also the channel‐forming peptide gramicidin‐A have been discussed on the basis of spatial structure and dynamic ...

Inorganica Chimica Acta, 1983
Abstract It will be shown using typical examples that it is possible to account, by explicit computations, for the complexing preferences of ionophores for certain cations. In the case of valinomycine, the preference observed for complexing the alkali cations is in the order Rb+ ∼> K+ > Cs+ ⪡ Na+, and can be accounted for by making an energy balance ...
