Park et al. have extended the nanoplasmonic array (10 × 10 array) platform to measure both internal (AKT1, HSP90, HSP70, TSG101) and transmembrane proteins (CD63, EpCAM, EGFR) in lysed EVs derived from ovarian cancer cells (Fig. 7e), coupled with induced localized amplified signals generated by immunogold labelling [94]. This evidence concerns the gene EPCAM and ovarian carcinoma.
