开发了一种糖链阵列平台,通过菌种促进的叠氮-炔环加成反应将糖链连接到等离子体纳米颗粒上。然后,可以使用表面增强拉曼光谱(SERS)以无标记的方式检测糖-蛋白质结合事件。作为概念验证,我们已经分析了Gal1、Gal3和流感血凝素(HAS)与各种糖链的结合,并证明了结合伙伴可以高度可信地被识别。表面增强拉曼光谱用于光学传感的吸引力在于它可以为糖蛋白复合体提供独特的光谱特征,通过统计验证来确认身份,并将间接方法常见的假阳性结果降至最低。此外,SERS非常灵敏,具有多路复用能力,从而允许同时检测多个分析物。
A glyco-array platform has been developed, in which glycans are attached to plasmonic nanoparticles through strain-promoted azide-alkyne cycloaddition. Glycan–protein binding events can then be detected in a label-free manner employing surface-enhanced Raman spectroscopy (SERS). As proof of concept, we have analyzed the binding of Gal1, Gal3, and influenza hemagglutinins (HAs) to various glycans and demonstrated that binding partners can be identified with high confidence. The attraction of SERS for optical sensing is that it can provide unique spectral signatures for glycan–protein complexes, confirm identity through statistical validation, and minimizes false positive results common to indirect methods. Furthermore, SERS is very sensitive and has multiplexing capabilities thereby allowing the simultaneous detection of multiple analytes.
