Advances in glycan-specific biomimetic molecular recognition and its biomedical applications

Glycan-mediated recognition is critically involved in a variety of pathophysiological events, so strategies targeting unique glycosylation could offer opportunities for novel disease diagnostics and therapeutics. Herein, we survey the current progress in glycan-binding entities and their biomedical applications. Particularly focusing on biologically promising artificial receptors, including boronate affinity-based molecularly imprinted polymers (MIPs) and anti-glycan aptamers, we summarize significant efforts in the recognition of glycans by MIPs and aptamers with high affinity and exquisite specificity. Furthermore, we highlight successful examples in biomedical fields of antiviral treatment, cancer diagnostics and targeted therapeutics. Finally, we briefly sketch the remaining challenges and future perspectives. Collectively, this review provides significant insights for further exploration of glycan-specific biomimetic materials in the broad biomedical area.
