The research group in Bioelectrochemistry and Biosensors of the University of Alcalá in collaboration with the Textile Industry Research Association (AITEX) has developed an electrochemical sensor of magnesium (Mg2 +) and a construction method based on the formation of a polymeric three-dimensional network that allows the entrapment / immobilization of a selective indicator for Mg2 +, eriochrome black T, by the use of a crosslinking agent and a polymer. The combination of these three reagents allows the construction of the sensor on any conductive surface, avoiding the electro polymerization of the indicator. The resulting sensor allows to measure MG2 + in any type of samples, without the need to add organic salts, additives or organic solvents. The quantification of Mg2 + is done directly by incubating the sensor in the sample containing the analyte, resulting in a modification of the amperometric signal proportional to its concentration. This method has many applications especially in health and biomedical sector since Mg2 + participates in such important activities as neuronal, neuromuscular transmission, or regulation of blood pressure and plays a key role in various pathologies such as vascular and migraines headache. The group is looking for companies in the agro-food, bio-sanitary and environmental sectors, with the aim of reaching technical collaboration agreements, commercial agreements or patent licenses.
