WebIn this work, chiral zinc oxide (ZnO) was first applied as selector to construct quartz crystal microbalance (QCM) sensor for enantioselective recognition of amino acids. The chiral ZnO was prepared by a methionine-induced self-assembly strategy and its high topological chirality was confirmed by several techniques such as circular dichroism ... WebChiral amines have found widespread application in asymmetric synthesis serving, for instance, as chiral bases in enantioselective deprotonation reactions 1,2 or being valuable substances for resolving racemic mixtures of acids. Additionally, chiral amines are prevalent, essential parts of many drugs and drug candidates.
