Early Diagnosis for Ovarian Cancer

  • Non-invasive in-vitro diagnostic method using exosome biomarker secreted from ovarian cancer cells
  • Ovarian cancer is one of the most difficult to diagnose early due to the absence of specific observable symptoms.
  • The survival rate is only 10 to 20% if detected at 3rd~4th stages, but the 5 year survival rate is 92% if detected early.
  • Lab testing method for early diagnosis of ovarian cancer by Harvard Medical School has been realized on the lab-on-a-chip.
  • Ovarian cancer cell-derived exosomes are reacted to antibody and enzyme in the LOAC chamber, and the cancer is detected by amplified electrochemical signals.

  • Just 10 uL sample can check the test results within one hour.
  • A substrate solution and an amplified circuit are used to efficiently detect the electrochemical signal, and to improve its sensitivity.
  • Signal amplification over the second time enhances the detection capacity 103 better than ELISA (Enzyme Linked Immunosorbent assay).
