外泌体最近已成为非常有前途的癌症生物标志物,因为它们在生物液中含量丰富,携带反映其起源细胞的蛋白质和RNA,并且在数周内保持稳定。除了丰度和稳定性之外,详细的外泌体分析在临床上还可用于诊断和分析癌症。尽管外泌体具有临床潜力,但快速量化外泌体及其分子信息的简单、可靠和灵敏的方法一直具有挑战性。因此,显然需要开发用于外泌体检测和分析的下一代传感技术。在这篇批判性评论中,我们将描述三种纳米技术传感平台,用于直接分析来自临床样本的外泌体蛋白和 RNA,并讨论未来的发展,以促进其转化为常规临床应用。
Exosomes have recently emerged as highly promising cancer biomarkers because they are abundant in biofluids, carry proteins and RNA reflecting their originating cells and are stable over weeks. Beyond abundance and stability, detailed exosome analyses could be clinically useful for diagnosing and profiling cancers. Despite their clinical potential, simple, reliable and sensitive approaches for rapidly quantifying exosomes and their molecular information has been challenging. Therefore, there is a clear need to develop next-generation sensing technologies for exosome detection and analysis. In this critical review, we will describe three nanotechnology sensing platforms developed for analysis of exosomal proteins and RNAs directly from clinical specimens and discuss future development to facilitate their translation into routine clinical use.
