Ovarian cancer (OC) is characterized by late stage discovery and low survivability. However, when diagnosed early (Stages I or II) the 5-year survival rate is 92% up from 29%.5 The extreme dichotomy in survivability is what makes OC a prime candidate for early diagnosis techniques. Exosomes, a subtype of extracellular vesicles, may bridge the gap between early and late diagnosis, but are lacking consistent isolation and detection technologies. Here poly(ethylene terephthalate) (PET) capillary channeled polymer (C-CP) fibers employing an HIC protocol are investigated as a novel exosome isolation method and a quick, inexpensive, and easy-to-use platform for OC diagnosis. The cell model system, immunoaffinity protocols, and biomarker identification tools developed here will aid in the refinement of a selective PET C-CP exosome isolation. The exosome isolation and diagnostic technique developed as a result of these investigations will allow for earlier and routine diagnosis of OC and save many women from one of the deadliest cancers.
