title: Glycan arrays: recent advances and future challenges.
abstract: Carbohydrate arrays, also referred to as glycan arrays, are composed of various oligosaccharides and/or polysaccharides immobilized on a solid support in a spatially defined arrangement. This technology provides a powerful, high-throughput approach to examining carbohydrate-macromolecule interactions, and glycan arrays have had a significant impact on the field of glycobiology. This review focuses on recent advances in glycan array technology, limitations, and opportunities for improvement. In particular, new methods for the production of natural glycan arrays and chemoenzymatic approaches are greatly expanding the diversity of structures on arrays. Since multivalent complex formation is generally required to achieve tight binding, methods to evaluate and modulate presentation are vital for enhancing the capabilities of this technology.
