(a) The confocal fluorescent images of dual-anti-Exos. The red fluorescence represents DSPE-PEG-aCD40-Alexa 647 and the green fluorescence represents DSPE-PEG-PLGVA-aPD-L1-Alexa 488. Scale bar: 2 μm. (b) Scatter diagram of exosomes, dual-anti-Exos, and MMP-2-responded dual-anti-Exos detected by flow cytometry. Inset figures: schematic diagram of the three different kinds of exosomes measured by flow cytometry. (c) Flow cytometry images of exosomes, dual-anti-Exos, and MMP-2-responded dual-anti-Exos.
