Hypothesis
Can a zwitterionic brush coating improve the accuracy and longevity of continuous glucose monitors?
Conclusion
The zwitterionic brush coating significantly enhances the performance and accuracy of continuous glucose monitors, especially during acute inflammation.
Supporting Evidence
- The zwitterionic brush-coated CGM showed better glucose tracking and reduced noise compared to the uncoated sensor.
- The Z-coated CGM maintained decent sensitivities for 12 days in protein-rich serum.
- Histological analysis showed reduced tissue response around Z-coated CGMs compared to uncoated ones.
- The zwitterionic coating improved the accuracy of CGM readings during acute inflammation.
Takeaway
This study shows that a special coating on glucose sensors helps them work better and last longer, making it easier for people with diabetes to monitor their blood sugar without pain.
Methodology
The study involved atmospheric plasma-induced grafting of a zwitterionic brush coating on glucose sensors and evaluated their performance in vitro and in vivo.
Limitations
Control over the thickness of the zwitterionic layer and uniform coating on nonplanar electrodes are challenging.
Participant Demographics
Eight-week-old male Sprague–Dawley rats were used for in vivo experiments.
