Vsebina:

Content (Syllabus outline):

Kemijski senzorji nasploh in analitični vidiki senzorjev; pomen uporabe optičnih kemijskih senzorjev ter prednosti in slabosti v primerjavi z elektrokemijskimi senzorji in ostalimi klasičnimi analiznimi metodami (npr. kromatografske metode, atomska absorpcija, masna spektrometrija).

Sestavne komponente optičnega kemijskega senzorja (indikatorji, polimeri, optična vlakna itd.) s poudarkom na senzorskem receptorju; optične lastnosti in način merjenja analiznih signalov (spektroskopske metode).

Uporaba optičnih senzorjev na različnih področjih – okoljevarstvo, varnost in zaščita, šport, medicina, inteligentne tekstilije, itd. in za določevanje različnih kemijskih in fizikalnih parametrov.

Trendi priprave nano-senzorjev in učinek nanodimenzij na senzorske karakteristike.

Individualna, poglobljena analiza, vezana na problematiko doktorske disertacije študenta.

Chemical sensors in general and analytical aspects of sensors, the importance of using fiber optic chemical sensors and the advantages and disadvantages in comparison with electrochemical sensors and other classical analytical methods (e.g. chromatographic methods, atomic absorption, mass spectrometry).

Constituent components of an optical chemical sensor (indicators, polymers, optical fibers) with emphasis on sensor’s receptor part; optical properties and measurement of analytical signals (spectroscopic methods).

Use of optical sensors in different areas – environment, safety and protection, sports, medicine, smart textiles, etc., and for the determination of a variety of chemical and physical parameters.

Trends in the preparation of nano-sensors and nano-size effects on the sensor’s characteristics.

Individual in-depth analysis related to the issues of the student's doctoral thesis.
