How affect the biosensing performance of Resonant Nanopillars arrays under dry conditions or immersed in fluid

In this work we demonstrate, for the first 3me, the advantage of performing the biosensing process of a refrac3ve index op3cal biosensor under dry condi3ons, in comparison with the biosensing structure immersed in fluid. We developed a biosensing experiment over a specific transducer based on resonant nanopillars (R-NPs) arrays. The op3cal interroga3on to monitor the recogni3on 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. We observed a significant enhance in the sensi3vity of the biosensing curve response for the R-NPs in dry condi3ons, leading an improvement of the Limit of Detec3on (LoD) in more than one order of magnitude. According to this result, any interferometric op3cal bio-transducer for in-situ diagnosis will improve the sensi3vity in case it can operate in dry condi3ons.
