A Butyrylcholinesterase Camera Biosensor Tested for Carbofuran and Paraoxon Assay

Figure 9

Comparison of standard spectrophotometric assays and colorimetric biosensor for measuring of cholinesterase neurotoxic inhibitor concentration. Sample 1 contained carbofuran 16 nmol/l, sample 2 carbofuran 32 nmol/l, sample 3 paraoxon ethyl 16 nmol/l, and sample 4 paraoxon ethyl 32 nmol/l. Standard error of the mean is depicted for five independent repeats (n = 5).
