Rodica Elena Ionescu earned one Ph.D. degree from the Ben-Gurion University of Negev, Israel in Biotechnological Engineering in 2004 and a second Ph.D. degree in Chemistry, from the University of Bucharest, in 2007. She has performed three post-doctoral positions in France in the field of electrochemical biosensors. Between February-October 2008, Dr. Ionescu was a researcher fellow at the National Nanotechnology Laboratory, Lecce (Italy) working on impedimetric cell-chips based interdigitated microlectrodes. In November 1st 2008, Dr. Ionescu joined the Université de Technologie de Troyes (UTT) as an Assistant Professor, becoming a member of the Laboratoire de Nanotechnologie et d’Instrumentation Optique (LNIO). In December 4th 2009, Dr. Ionescu obtained the Habilitation Title for conducting independent research (HDR) equivalent to an Associate Professor position. Thanks to the obtained research grants, Dr. Ionescu developed novel acoustic and optical platforms for ultrasensitive detection of biomolecules and pesticides. In 2012, Dr. Ionescu was awarded with a national OSEO Innovation grant. Between April 1st 2014 to March 30, 2015 Dr. Ionescu was the research manager of a Proof-of Concept (POC) Grant-NRF-POC 002-026 supported by the Singapore National Research Foundation concerning the Electrochemical lateral flow biosensor detection and quantification of Dengue virus in whole blood at the Nanyang Technological University, School of Materials Science and Engineering under an international CREATE-NTU-HUJ-BGU program. Her current research activities include the development of multi-analyte biosensing platforms, specific (bio)functionalization of surfaces, atomic force microscopy nanopipette applications, controllable synthesis of nanoparticle, evaluation of nanoparticles and water pollutants toxicity to living cells and microorganisms.

Incident light interacting with noble-metal nanoparticles with smaller sizes than the wavelength of the incident light induces localized surface plasmon resonance (LSPR). In this work a gold nanostructured surface was used for the immobilization of a 5′ end Thiol modified DNA probe to develop a LSPR nanobiosensor for the detection of the spoiler wine yeast Brettanomyces bruxellensis. Gold was evaporated to obtain a gold thickness of 4 nm. DNA (2 μL) from the target microorganism and the negative control at various concentrations were used to test the specificity and sensitivity of the LSPR technique. Changes in the optical properties of the nanoparticles due to DNA-probe binding are reflected in the shift of LSPR extinction maximum (λmax). The results obtained using as target microorganism B. bruxellensis, and as negative control Saccharomyces cerevisiae demonstrated the specificity of both the DNA-probe and the protocol. The LSPR spectrophotometry technique detects 0.1 ng/μL DNA target confirming the possibility to utilize this system for the detection of pathogen microorganisms present in low amount in food and beverage samples.
