Since its establishment in 1974, magnetic carrier technology (MCT) has been widely used in bioseparation. As a commonly used magnetic carrier, Fe3O4 can be modified as magnetic nucleus to be used in the extraction of target analytes.
The copper-catalyzed azide-alkyne cycloaddition reaction is a representative example of click chemistry, which proceeds with high regioselectivity when terminal alkynes are used and provides 1,2,3-tri-azoles with 100% atom efficiency. This important reaction has attracted a considerable amount of attention in organic synthesis, medicinal chemist...
