We would like to correct two errors in the Supporting Information of our original paper. An error occurred on page S5 of the Supporting Information. For the cell culture conditions, a 10 cm culture dish should be written instead of a 10 mm culture dish. The other is Figure S2 in the Supporting Information, in which the protein profiles of exosomes from a urine sample are shown in lanes UC and MagG@PEI@DSP@aptamer and what should be presented here is the protein profiles of the exosomes in the cell culture medium isolated by UC and MagG@PEI@DSP@aptamer. This error was introduced during the revision process, and it does not affect any of the results or conclusions. The corrected figure should be as follows. Figure S2. SDS-PAGE analysis of concentrated medium and the captured exosomes from the cell culture medium by UC and MagG@PEI@DSP@aptamer. This article has not yet been cited by other publications. Figure S2. SDS-PAGE analysis of concentrated medium and the captured exosomes from the cell culture medium by UC and MagG@PEI@DSP@aptamer.

修正适体功能化聚乙烯亚胺修饰磁性氧化石墨烯复合材料的合理合成，用于外泌体的高效富集和综合代谢组学分析

我们想更正原始论文的支持信息中的两个错误。支持信息的 S5 页发生错误。对于细胞培养条件，应编写 10 cm 培养皿而不是 10 mm 培养皿。另一个是支持信息中的图 S2，其中尿样中外泌体的蛋白质谱显示在泳道 UC 和 MagG@PEI@DSP@aptamer 中，此处应呈现的是细胞中外泌体的蛋白质谱UC 和 MagG@PEI@DSP@aptamer 分离的培养基。此错误是在修订过程中引入的，不影响任何结果或结论。修正后的数字应如下所示。图 S2。UC 和 MagG@PEI@DSP@aptamer 对浓缩培养基和从细胞培养基中捕获的外泌体进行 SDS-PAGE 分析。这篇文章还没有被其他出版物引用。图 S2。UC 和 MagG@PEI@DSP@aptamer 对浓缩培养基和从细胞培养基中捕获的外泌体进行 SDS-PAGE 分析。
