About

Biography:

Prof. Izabela Naydenova is a Lecturer at the School of Physics and Clinical & Optometric Sciences and a PI at the IEO Centre, Dublin Institute of Technology (DIT). She was awarded her MSc in Applied Optics from the University of Sofia (1993) and her PhD in Physics from the Bulgarian Academy of Sciences (1999). After postdoctoral positions at the Institute for Physical and Theoretical Chemistry, Technical University of Munich and the IEO Centre, DIT she took up her current academic position in the School of Physics in 2008. She has over 120 publications in the field of holography and holographic applications. Prof. Naydenova has supervised 10 PhD students to their completion and more than 35 BSc Hon degree students. She is a member of OSA and SPIE and advisor for their DIT student chapters.

Interests:

As part of the ESA topical team we envisage the development of sensors for detection of biological and chemical substances that are closely related to the tissue healing process. The development of appropriate holographic temperature and pressure indicators is also envisaged. The sensor structures will be designed, fabricated and tested, initially in laboratory conditions and later tested in the field. The performance of these innovative sensors will be compared with the existing methods of detection. The main performance indicators will be their stability, selectivity, sensitivity and signal to noise ratio.

Expertise:

The sensors developed at the Centre for Industrial and Engineering Optics, Dublin Institute of Technology are based on functionalised photonic structures fabricated by holographic recording. Both surface and volume photonic structures have been utilised, since each of the two configurations has its advantages and disadvantages. Surface sensors for example are easier to functionalise (by spin coating of the functionalising layer on top of the structure) and they have faster response times, but their dynamic range is limited. Volume sensors have a slower response due to the longer diffusion distances, are more difficult to functionalise but they have larger dynamic range. The holographic sensors group at the IEO centre has been successful in the design and fabrication of sensors for different analytes/stimuli among which are relative humidity, temperature, metal ions detection and pressure.

Available equipment and techniques:

The group has five fully equipped optical laboratories with appropriate holographic set-ups for recording of the photonic devices. Lasers emitting from UV to near IR are available. Access to state of the art instrumentation for spectroscopic characterisation (UV-VIS, Raman and Infrared spectroscopy) and imaging (scanning probe AFM, conductive AFM) and electron microscopy (SEM, WDX, EDX, variable pressure/cryo SEM, TEM) is available through FOCAS institute, DIT, http://www.dit.ie/focas/ .
