细胞外囊泡(EV),从各种肿瘤和宿主细胞中主动脱落,在血液中丰富,并携带来自亲本细胞的分子标记物。由于这些原因,EV作为疾病的生物标志物获得了很大的兴趣。在已经开发的许多不同的分析方法中,表面等离子体共振(SPR)由于其灵敏度,鲁棒性和可重复性而脱颖而出,成为理想的技术之一。在这篇综述中,我们比较了不同的SPR平台的EV分析,包括传统的SPR,纳米等离子体传感器,表面增强拉曼光谱,等离子体增强荧光。我们讨论了用于捕获靶向EV的不同表面化学物质,并对其蛋白质和RNA进行分子分析。我们还强调了这些等离子体平台的临床应用,包括癌症,神经退行性疾病和心血管疾病。最后,我们讨论了电动汽车等离子体传感的未来前景及其商业化和临床转化的潜力。
Extracellular vesicles (EVs), actively shed from a variety of neoplastic and host cells, are abundant in blood, and carry molecular markers from parental cells. For these reasons, EVs have gained much interest as biomarkers of disease. Among a number of different analytical methods that have been developed, surface plasmon resonance (SPR) stands out as one of the ideal techniques given its sensitivity, robustness, and ability to miniaturize. In this review, we compare different SPR platforms for EV analysis, including conventional SPR, nanoplasmonic sensors, surface-enhanced Raman spectroscopy, and plasmonic-enhanced fluorescence. We discuss different surface chemistries used to capture targeted EVs and molecularly profile their proteins and RNAs. We also highlight these plasmonic platforms’ clinical applications, including cancers, neurodegenerative diseases, and cardiovascular diseases. Finally, we discuss the future perspective of plasmonic sensing for EVs and their potentials for commercialization and clinical translation.
