Specific colorimetric detection of cyanide triggered by a conformational switch in vitamin B12

Inorganic Chemistry

Abstract

"Base on"/"base off" coordination of the intramolecular bound benzimidazole nucleobase of vitamin B 12 allows the specific colorimetric detection of millimolar concentrations of cyanide in water. In various competition experiments, it was demonstrated that up to 12 different anions as well as a 1000-fold excess of Cl (-) over CN (-) do no interfere with the sensor. An 8-fold increased sensitivity in the "naked eye" detection of CN (-) was observed when water was replaced by MeOH/H 2O (5%) as a solvent.

Anthelmintics

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
