Figure 9.7 Dependency of biosensor response (μS) on BSA concentration.
concentration evaluated by a micro-BCA protein assay) have been
shown. Correlation coefficients of 0.89 and 0.92 were, respectively,
obtained.
In the next work [64], two enzymes, proteinase K and pronase,
were used for the creation of conductometric biosensors for protein
detection. The biosensor with proteinase K and pronase gives a
higher signal and a response in close agreement with the variations
in total organic carbon and organic nitrogen concentrations; this
biosensor was then ...
