Description

The actual environmental situation requires the continuous in-situ information of some chemical parameters as well as in focal points as in cases of diffuse contamination, which permits to analyse their impact. With this in mind, we plan to develop new analytical instrumentation, which combines integration and miniaturization. This project focuses on a technological side of the construction of electrical and optical microsensors and flow Microsystems, and on the chemical research in the field of new recognition reagents and their immobilization in different matrices. First of all, we aim to take profit of the advantatges of using previous miniaturized and integrated analysers. The intention is to miniaturise all of the analytical process steps until obtaining a useful instrument for the in-situ chemical analysis of common quality parameters (nitrate, ammonium, nitride, phosphate, pH, oxygen, etc...) and other specific parameters (pesticides, toxins, heavy metals, etc..) in water samples.With this proposal, the study of new optical transduction techniques will be used for the fabrication and integration of new optical transduction techniques will be used for the fabrication and integration of new optical sensors based on optical fibres and integrated optics. The sensors will use all analytical techniques based on optical effects to achieve reliable and sensitive micro-optical sensors for environmental applications. Moreover, the integration of the different sensors together with optoelectronic instrumentation will produce complete instruments to the measurement of different target analytes. Furtermore, flow Microsystems will be performed by the synthesis and characterization of new selective membranes will be performed by the synthesis and characterization of new recognition elements as ionophores and chromoionophores, and the use of biological material, as enzymes. To attain thses objectives, a multidisciplinary team has been formed, which comprises (...)
