Webb1 mars 2010 · The linear equation was Bresponse (μA) = 0.323 [glucose] (m M) + 0.634 (μA); n = 24, r2 = 0.994. Conclusion: Results showed that the resultant NIDE glucose biosensor increases the dynamic range, device sensitivity, and response time and has excellent detecting performance for glucose. References 1. WebbThe detection limit was also investigated and measured as 0.77 µM. Response time of the biosensor was also determined as 30 s. Repeatability of the urea biosensor system was found to be very high, and it was demonstrated that response of the urea sensor was protected by 95.7% at the end of the 170th reuse.
WebbThe latest published article "Printed flexible bi-functional electrochemical Urea-pH sensor based on MWCNTsPANi electronic ink" was published in the journal "Journal Of Electronics Materials", It presents a simple, novel, binder-free, low-cost technique for non-enzymatic urea-pH detection.
