Nitric oxide NO) plays a variety of complex roles in the genesis, growth and death of cancer cells/tumors. As it does in so many physiological processes, it exhibits both pro- and anti-tumor activities, and researchers are still discussing the implications of these data on the use of NO as a therapeutic agent for the treatment of cancer.

A recent study takes advantage of NO activity to make diagnosing cancer more certain. A novel microneedle biosensor electrically detects NO emissions from cancer tissues in real-time for in situ cancer diagnosis during endomicroscopy. Researchers showed that using this as a dual diagnostic system yields high resolution imaging and provides a new way to easily, quickly and accurately diagnose cancers.

Nitric oxide once again takes a starring role in science’s efforts to understand how the human body works.
