Mediator Chemistry: Ferrocene vs. Osmium vs. Ruthenium
Mediator chemistry drives diabetic test strips. It measures blood glucose levels. Three key players emerge: ferrocene, osmium, and ruthenium.
Key Mediators
- Ferrocene: stable and low-cost, making it a popular choice.
- Osmium: highly sensitive, but toxic.
- Ruthenium: balances stability and sensitivity.
These mediators spark electron transfer, generating a signal that's proportional to glucose levels. Their properties impact test strip accuracy and reliability.
