Other quantitative model-building tools

Although the above-mentioned methods cover most of the quantitative model building tools that are available in current commercial software, there are several other useful methods that were not mentioned. Many of these are simply extensions of the methods already discussed. A more complete list of such tools is also available. l 44 47 9

The work reported the applicability of a voltammetric BioET to the monitoring of different phenolic pollutants present in wastewaters. Voltammetric responses obtained from an array of bulk-modified (bio)sensors, containing enzymes such as tyrosinase and laccase, were combined with chemometric tools such as ANNs for building the quantitative prediction model. The four voltammetric electrodes prepared consisted in one blank electrode plus three (bio)composite electrodes modified with tyrosinase, tyrosinase-i-laccase and Cu nanoparticles. This choice was intended as to maximize the response of the (bio)sensor array towards phenolic compounds. That is, on one side, tyrosinase and laccase were chosen as they are extensively used for the development of amperometric biosensors aimed to the detection of phenolic compounds on the other side, copper nanoparticles were also considered due to the well-known catalytic properties of nanoparticles and the importance of copper in the two enzymes used. To fully exploit all the information...
