Carbohydrate Microarrays by Microcontact “Click” Chemistry

Abstract

Carbohydrate microarrays can be prepared by microcontact printing of carbohydrate alkyne conjugates on azide self-assembled monolayers (SAMs). The carbohydrates are immobilized by a "click" reaction in the contact area between the stamp and the substrate. The immobilized carbohydrates retain their characteristic selectivity toward lectins.
