Forging sustainability

Chemical Sensors Laboratory (LOCS)


The main objective of the LOCS is the development of new chemical sensors tailored for specific applications. LOCS main research areas are: (i) manufacture of prototypes based on several transducers (acoustic wave sensors, potentiometric sensors, amperometric sensors, and optical sensors); (ii) selection and synthesis of  new sensing materials (plasticized PVC/ionophores, molecularly imprinted polymers, conducting polymers, pyrrole based synthetized molecules and polyoxometalates, enzymes, and aptamers); and (iii) assembling arrays of sensors ( electronic noses and tongues). LOCS has diverse fields of application including:

Besides this, LOCS also have some work developed in the field of education in chemistry namely related with the Determination of the Faraday Constant and corrosion studies. From our work, several prototypes have resulted, namely cells for acoustic wave sensors for voltammetric studies, flow injection studies, permeation studies, and potentiometric electronic tongue. Presently, LOCS has a a laboratory  equipped with basic instrumentation for its mission (e.g. pH meter, Frequency meters, Network/Spectrum/Impedance Analyser, Function generator, Adjustable power supplies, 2 channel oscilloscope, Spin coater, Modular spectrophotometers for absorbance, fluorescence and reflectance, Automatic titrator, Electronic tongue, Electronic nose, Counter/Timer PXI 6608 (National Instruments), High impedance digital voltmeter, Programmable oven, Potentiostat / galvanostat).
