A method for voltage measurements of cancerous vs non-cancerous omentum

This paper presents and elaborates upon the practicalities of a method which enables the recording of voltage measurements from omental tissue in patients with advanced ovarian cancer. The key components of the proposed low-cost experimental setup are a tungsten electrode, a Ag/AgCl reference electrode and an instrumentation amplifier. Intriguingly, potential difference recordings between cancerous omentum and tissue culture media and between non-cancerous omentum and media, differ for tissue samples coming from the same patient. Further studies are warranted to assess the potential prognostic value of voltage measurements in cancerous tissue.
