Qualifications
Salzitsa Anastasova received her BSc in Analytical Chemistry in 2002 and obtained PhD in Inorganic and Analytical Chemistry in 2008 from University of Sofia, Bulgaria. The PhD thesis entitled “SiO2-based Ru(II)-containing films as oxygen sensors” was performed under supervision of Professor Dimitar Todorovsky and Assoc. Professor Maria Milanova. In 2008 she moved to Germany to work as a research scientist at University of Regensburg and later she moved to Ireland to become a postdoctoral researcher at Dublin City University. Her research interests involve studying and development of potentiometric and optical sensors for environmental and biomedical applications. She is currently working on a multinational FP6-MATERA-ERA-NET project with the goal of development miniaturized potentiometric sensing system for the detection of analytes important for health and environment.
Project Summary
MASTRA Project - MASTRA is a part of ERA-Net Materials, a speciality field within the ERA-Net network created by the European Union with the aim to enhance cooperation between European researchers. Abo Akademi University’s project partners are AGH University of Science and Technology, the polish company DNH, the Irish Dublin City University, Environmental Protection Agency, and the international company Thermo Fisher Scientific’s unit in Finland. In potentiometric measurements with chemical sensors, two electrodes are needed: an ion-selective electrode and a reference electrode. In the MASTRA project these two types of electrodes are developed based on solid materials. In MASTRA each unit has its role and none of the teams could accomplish the project alone. Knowledge has to be combined. The group in Finland are working on the reference electrodes. The Polish researchers are modelling the origin of signals in electrodes in order to get e theoretical background for optimizing the ion transport. Here in Dublin City University we are working on ion-selective membranes. The purpose is to receive good ISEs with lower detection limit, simple construction, low production cost and low power requirements that will make ISEs ideal candidate for detector systems that can be integrated into autonomous, deployable sensing devices.
More investigations will answer to what extent we can evaluate the functionality (damaged, fouled, components leached out – “good” or “bad”) of these sensors using a simple electric signal. This will be a vital tool for probing the condition of remotely deployed ISEs in widely distributed chemo-sensor networks (e.g. for environmental monitoring) and for enhancing the reliability of these devices, and thereby simplifying the way in which they are used.Our ultimate goal is to implement such tools so that ISEs can be deployed for weeks or months with minimal calibration or maintenance (ideally none or only at intervals detected by the sensor condition monitoring tools).
