Photo-Click Immobilization of Carbohydrates on Polymeric Surfaces-A Quick Method to Functionalize Surfaces for Biomolecular Recognition Studies

Methods to rapidly functionalize specific polymeric surfaces with alkynes, which can subsequently be linked to azide-containing carbohydrates, are presented. The methods comprise two main concepts: azide photoligation and Cu-catalyzed azide-alkyne cycloaddition. 2-Azidoethyl-functionalized CL-D-mannopyranoside was synthesized and covalently attached to alkyne-functionalized polymeric surfaces using the techniques. The protein recognition properties of the carbollydrate-presenting surfaces were evaluated using quartz crystal microbalance biosensor instrumentation.
