Course Description

Sensor Systems


Ecotechnologies, third-level study programme


prof. dr. Aleksandra Lobnik


• Introduction to optical sensors for food quality
• To gain planning of specific sensors system for determinate analyte
• To identify possibility to use optical chemical sensors in real environment
• To widen knowledge from instrumental analytics to in-situ, on-line sensor micro and nano systems


• Introduction to sensor systems and their definition
• Chemical receptors
• Biochemical Receptors
• Review of most important polymer matrixes used in optical chemical/bio sensors which are used by analyte detection typical for food control
• Imobilization methods (electrostatic, covalent, doping methods...)
• UV/VIS absorption and luminiscence spectroscopy, IR spectroscopy
• Molecular imprinted polymers as sensors for analytes (covalent and electrostatic binding, polymer matrices, analyt, examples)
• Optical chemical sensors and optical fibres for in-situ, on-line detection
• Micro and nano sensors
• Examples of optical chemical sensors and their applications in food control
• Sensor validation using classical analytical methods (chromatographic…)
• Sensor systems and their transfer from the lab to the real environment

Seminar work:
• Literature overview in the area of optical chemical /biosensors for food quality control
