SCIENCE

The Claim

Electrochemical enzyme-based biosensors can detect metabolites such as glucose and lactate associated with tumor metabolism.

Verified by Lenz ·

The Short Version

Published studies support that electrochemical enzyme-based biosensors can detect tumor-related metabolites such as glucose and lactate. Evidence includes cancer-cell and tumor-sample experiments using glucose- and lactate-oxidase sensors. The main caveat is that many demonstrations are proof-of-concept or ex vivo, so capability is established more clearly than routine clinical use.

Caveats

  • This statement supports analytical capability, not routine clinical validation or widespread oncology deployment.
  • Performance can degrade in tumor-relevant conditions such as acidic microenvironments, which may limit reliability.
  • Many cited demonstrations are controlled, ex vivo, or single-cell experimental setups rather than standard in situ tumor monitoring.
