1st talk:


In this talk it will be presented the more relevant results concerning the research developed during the PhD project in the field of refractometric configurations suitable for label-free chemical and biological sensing. Refractometric label-free systems, allow the direct detection of biological or chemical analytes, without using any colorimetric marker. It requires, instead, the design of sensitive layers that experience a refractive index change in presence of the target. It is achieved using biomolecules with a natural affinity to the target, or chemical species having analyte specific ligands. Few configurations using different photonic structures ranging from coated long period gratings, multimode interference devices and white light differential systems will be addressed.

About Dr. Carlos Gouveia:

Carlos Gouveia received the PhD in Electrical Engineering (2014) from University of Madeira (Portugal). Additionally, has BSc. and MSc in Electrical Engineering and Telecommunications from the University of Madeira. He has more than 6 years’ experience in research in the field of optical fiber sensors for diverse applications at the Optoelectronics Unit of INESC Porto (Portugal). His main areas of interest are: Fiber Optics, Fiber Optic Sensors, Interrogation Systems, Instrumentation, Signal Processing.

2nd talk:


A biosensor is an analytical device that responds to an analyte present in a sample and interprets its presence or concentration as an appropriate signal via a suitable combination of a biological recognition system and a transducer. These devices are playing an increasingly important role in providing analytical information in all sectors of human interest, from medicine to environmental monitoring, food safety, military, defence and security. Particularly, biosensors constitute the basis of cheap, simple devices for acquiring chemical or biological information, bringing sophisticated analytical capabilities to the non-specialist and general public. Despite the market opportunities for the rapid exploitation of novel developments are significant, there are only a few successful commercial biosensor products available. The main limitations on the commercialization of biosensors relate to the technical and manufacturing feasibility, market value and investment strategies. The commercialization of biosensors requires the optimum use of emerging technology, nature-inspired, and cutting-edge engineering to design and produce functional systems at the lowest cost.

About Dr. Raquel Queirós

Raquel B. Queirós graduated in 2007 in Chemical Engineering and achieved, in 2008, a Master degree in Technologies for Environmental Protection from Instituto Superior de Engenharia do Instituto Politécnico do Porto. She concluded her PhD in Physics at University of Porto in collaboration with Associated Laboratory INESC TEC and BioMark-Sensor Research/ISEP on the development of biosensors for detection of aquatic bacterial contamination. Her interests included the synthesis and characterization of new biomimetics materials, development of fiber optic evanescent platforms for sensing purposes for application in agri-food traceability and safety, environmental monitoring and bioprocess control. She is a member of International Society for Optical Engineers (SPIE) and former President of the University of Porto SPIE Student Chapter.
