The LIA group has submitted a patent application for the design of this logical DNA sensor. These sensors are able to represent logical implications (or IF-THEN rules), like, for example, IF symptom 1 and symptom 2 are present, THEN the disease is A, or IF the disease is B, THEN symptoms 2 and 3 must be present.
The sensors are able to use these logical rules to autonomously run logical inference processes on the genetic input signals and reach accurate diagnoses.
Using these intelligent DNA sensors as basic building blocks, the aim is to develop in vitro systems capable of autonomously detecting a set of input symptoms and output a diagnosis or release the right drug.
These biological sensors (built with DNA to process DNA) are considered bionanotechnological devices and are part of a discipline called DNA computing or biomolecular computing. This discipline aims to build and program devices manufactured with biomolecules, such as, for example, DNA strands to process information likewise encoded in other biomolecules.
In short, there is a need to develop and manufacture biological sensors capable of precisely detecting complex combinations of genetic signals and autonomously issuing the respective diagnoses.
The bionanotechnological devices developed by the UPM's LIA group at the Facultad de Informática are a response to this need.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
