Recently, many new types of glycodendrimers have been designed and synthesized as the mimics of nature carbohydrate clusters for multivalent interaction with the corresponding receptors. Due to their unique properties and special structure features, glycodendrimers have attracted many attentions in biomedical field. Many reports have demonstrated the potential application of glycodendrimers on drug transportation, receptor antagonist, vaccine, and medical diagnosis. This article will focus on the review of the synthesis of glycodendrimers and their potential applications in the last decade.
