This project has the aim to develop sensors applied to the analyses of forensic samples, such as explosives and drugs of abuse. The analyses of those samples will be performed with devices named electronic/colorimetric tongues. Those devices use the information obtained with the electrochemical and colorimetric techniques along with chemometrics methods. The construction of the electronic/colorimetric tongues will follow a methodology taking into account the easiness of disseminations, the reproducibility and the accessible price, i.e. the construction of disposable electrodes from gold CDs. The chemometrics analyses will be accomplished mainly by PCA (Principal Component Analysis) and/or HCA (Hierarchical cluster analysis). Quantitative analyses will also be performed with PCR (Principal Component Regression) and PLS (Partial Least Squares).
