ABSTRACT

In the last decades, optomechanical resonators have been the subject of extensive research in a variety of fields, such as communication, signal processing, novel quantum technologies and advanced sensing. This talk focuses on the recent advances performed in the optomechanics field regarding their application as biological sensors. In particular, I will show the different optomechanical devices we have developed in the BioNanoMechanics Laboratory: nanowires, nanodisks and microcapillaries. Each of these devices are specifically designed for detecting, characterizing and identifying particular bioentities, mainly depending on their sizes. While microcapillars are ideally suited for human cells applications, nanodisks can applied for bacteria and virus, and nanowires for proteins.  In the near future, optomechanical devices may provide many different applications in the clinical diagnosis and biomedicine fields. Among them, it is worthy to highlight the prompt diagnosis of infectious diseases and cancer, as well as the development of novel drugs, such as, antibiotics.

Brief resume of Eduardo Gil Santos´ Curriculum Vitae

duardo Gil Santos graduated in Physics in 2007 (USC). He joined the Bionanomechanics Laboratory (CSIC) in October 2007 through a national competitive grant (JAE Predoc). He obtained his PhD in Physics in May 2012. At that time, he worked on the development of novel devices, concepts and techniques in order to improve the capabilities of micro- and nano-mechanical sensors, always looking for biological and biomedicine applications.

In February 2013, he joined the Materials and Quantum Phenomena Laboratory (Paris Diderot University, France) thanks to an international competitive grant (Research in Paris). During this time, he learnt theoretical and experimental aspects about optomechanical devices and their applications. He opened a new research line focused on the development of optomechanical resonators for sensing applications.

In November 2016, he came back to the Bionanomechanics Laboratory by means of a European grant (Marie Sklodowska-Curie Actions, Individual Fellowship) with the goal of applying optomechanical devices as biological sensors. Currently, he is a «Ramón y Cajal» researcher working at the Bionanomechanics Laboratory.

In the last years, he has obtained six national project as principal investigator (ComFuturo, RETOS, «Ramón y Cajal», «Intramural Especial», «Fundación Ramón Areces» and «Leonardo») which has enabled him to consolidate his own research line. His main research objective is to develop optomechanical devices as biological sensors, definitively bringing them to the society. Apart from his own projects, he is involved in several European projects (ERC-CoG and FET-proAct, among others).

His scientific work has been published in 1 book chapter, 30 ISI-indexed articles and 4 patents (1 licensed, 2 granted and 1 registered). This work has received 831 citations (WoS), with an h-index of 16 (WoS).
