Table 4 presentsrecent studies regarding cancer diagnosis. Within the scope of anotherresearch, a localized fluorescent imaging technique was created toanalyze several proteins within each EV.143 EVs were extracted from the clinical plasma sample using a biochipengineered with anti-CD9 antibody. Subsequently, the EVs collectedunderwent particular identification by utilizing various DNA aptamers(CD63/EpCAM/MUC1) as shown in Figure 7D. This was followed by the implementation of rollingcircle amplification, which produced localized fluorescent signals(Figure 7E). Here, CD63 is linked to cancer.
