Metabolic oligosaccharide engineering (MOE) is a classical strategy for carbohydrate perception but suffers from glycan quantification. Here the authors develop a selenium-based metabolic oligosaccharide engineering strategy (SeMOE), based on elemental analysis, to quantitatively detect and visualize glycans both in vitro and in vivo.
