细胞外囊泡(EV)是细胞分泌的纳米和微米尺寸颗粒,由含有核酸和蛋白质的脂质双层组成,用于诊断和治疗应用。 EV 固有的复杂性是生物纳米囊泡各种潜在应用(包括分析)中异质性的根源。为了减少异质性,电动汽车应根据其大小和货物进行隔离和分离。然而,目前的技术还不能满足要求。我们展示了根据电动汽车的尺寸进行无创且精确的分离,没有任何可识别的损坏。我们通过本系统的操作分离了阿托升体积的生物纳米粒子,显示在一小时内处理相对较大体积的样品至毫升。通过 TEM 分析,我们观察到了 30 至 100 nm 的外泌体和凋亡小体的明显大小和形态差异。事实上,我们通过免疫印迹法和非侵入性分离的 EV 证实了生物部分的变异,为生物纳米颗粒的研究和应用打开了新的窗口。
Extracellular vesicles (EVs) are the cell-secreted nano- and micro-sized particles consisted of lipid bilayer containing nucleic acids and proteins for diagnosis and therapeutic applications. The inherent complexity of EVs is a source of heterogeneity in various potential applications of the biological nanovesicles including analysis. To diminish heterogeneity, EV should be isolated and separated according to their sizes and cargos. However, current technologies do not meet the requirements. We showed noninvasive and precise separation of EVs based on their sizes without any recognizable damages. We separated atto-liter volumes of biological nanoparticles through operation of the present system showing relatively large volume of sample treatment to milliliters within an hour. We observed distinct size and morphological differences of 30 to 100 nm of exosomes and apoptotic bodies through TEM analysis. Indeed, we confirmed the biological moiety variations through immunoblotting with noninvasively separated EVs opening new windows in study and application of the biological nanoparticles.
