Porphyrin-based covalent organic framework as bioplatfrom for detection of vascular endothelial growth factor 165 through fluorescence resonance energy transfer.

本研究构建了一种基于卟啉基共价有机框架（p-COF）和碳点（CDs）的荧光适配体传感器，用于检测血管内皮生长因子165（VEGF165）并对乳腺癌细胞系MCF-7进行成像。通过柠檬酸和尿素热解制备的CDs具有约380 nm的强光致发光，作为荧光供体标记VEGF165靶向适配体，形成AptVEGF/CDs复合物。p-COF由TAPP和...
