where c is the concentration of sulfite, with standard error of
the regression = 0.011A, and 95% confidence interval on a
measurement of 0.500mM sulfite of ±0.045 mM.
Compared with the sulfite biosensor fabricated by Situmorang
et al. [4] using electrodeposited polytyramine, this
fill and flow biosensor has a wider linear range and better
response time, but at the cost of poorer sensitivity and detection
limit.
