This year the meeting has been organized in two days. One for the presentation of research and technology transfer (patents) and the second day is for networking between our researches and the large number of engineering companies in the industrial sector, that will present their research work.
During the event, Ana López Hernández from UPM presented the poster “How affect the biosensing performance of Resonant Nanopillars arrays under dry conditions or immersed in fluid”
It reflects the work developed for the comparison of the Resonant Naopillars transducers, proposed for the chemical detection unit of the Enviguard Project, when measuring them immersed in a fluid or in dry conditions.
The transducer is based on resonant nanopillars (R-NPs) arrays. The optical interrogation to monitor the recognition events was firstly performed with the R-NPs in dry, only in contact with the air, and secondly with the R-NPs immersed in water. It was observed a significant enhance in the sensitivity of the biosensing curve response for the R-NPs in dry conditions, leading an improvement of the Limit of Detection (LoD) in more than one order of magnitude. According to this result, any interferometric optical bio-transducer for in-situ diagnosis will improve the sensitivity in case it can operate in dry conditions.
