Carbohydrate nanotechnology: integration of glycans and nanomaterials

Glycoworld has synthesized and studied carbohydrate molecules to determine their utility in biosensing and electroanalytical applications.

In collaboration with Professor Keith Stine (UMSL) we studied the application of porous nanostructured materials to the supported synthesis of glycans. We have also investigated the application of porous nanomaterials to detecting carbohydrate-protein interactions by electrochemical and spectroscopic means.

Other applications of nanoporous gold material include separation, enrichment, and biosensing of glycoproteins.

Other projects: metal complexes, thermochemical, and theoretical studies

Glycoworld has been involved in several other collaborative and individual projects that span across a few research areas including metal complexes with carbohydrates and thermochemical studies.
