Dublin Institute of Technology (DIT) researchers have invented a unique, patented hologram that changes colour under pressure and has widespread applications for security, authentication and environmental sensing. Holograms are frequently used for security and authentication, and are commonly found on credit cards, bank notes, passports and concert tickets, as well as on a number of high value goods such as pharmaceutical drugs, clothing and accessories. They can also be used as sensors if the hologram is sensitive to changes in its environment, and for tamper detection for document security. Current holographic solutions are usually mass produced from a single master hologram, resulting in identical holograms, with serialisation applied via standard overprinting, allowing the holograms to be either tampered or copied. The pressure-sensitive optical device developed at DIT allows the production of true individual holograms. Specific customer codes can be embedded into the actual hologram during manufacture, making them extremely difficult to copy but very easy for the end user authentication through a pressure-induced colour change of the hologram. The colour change can be either temporary or permanent, depending on specific requirements. This optical device can be a purely visual feature to be used for authentication by the end customer/consumer using thumb pressure, or it can also be designed to be machine readable for automated checking within the supply chain.

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.
