Abstract: Aluminum coated glass slides provide a novel glycan array platform. Specifically, aluminum coated glass slides increase sensitivity of fluorescent based assay methods. Additionally, aluminum coated glass slides allows for mass spectroscopic analysis of carbohydrates and provide a platform for examining activity of cellulases. The unique properties of ACG slides include: the metal oxide layer on the surface can be activated for grafting organic compounds such as modified oligosaccharides; the surface remains electrically conductive, and the grafted oligosaccharides can be simultaneously characterized by mass spectrometry and carbohydrate-binding assay; and the slides are more sensitive than transparent glass slides in binding analysis.
