4. Conclusion
The presented fructose biosensor, based on the combination of
fructose dehydrogenase, carbon nanotube based electrode and a
highly original osmium redox polymer, will form the basis of a
new, rapid and portable method for determination of fructose in
food analysis. The preparation of the biosensor is very simple,
cheap and not time-consuming. The biosensor showed a good linear
range, low detection limit (1
lM), good reproducibility, good
stability and a fast response time. It was also not influenced by
possible interferents which can be present in food matrices.
For these reasons, this new, low cost and disposable fructose
biosensor prototype would be suitable for possible use in food
industries.
