Biogenic amines (BA) are toxic substances. They are pollutants in industrial and manufacturing areas, becouse they are widely used in preparations of pharmaceutical, biological, medical and food produtcs. Many microorganisms species produce biogenic amines in or on food and this can cause strong toxical effects on consumers. Biogenic amines are therefore an indicator of food quality. A new class of chemical sensors has been investigated that interacts with biogenic amines, such as putrescine, resulting in a naked eye observed optical change of sensing film optode.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 14003222The award was granted based on the research work done in the »Centre of sensor technology«, where Prof. Lobnik is the head. The Centre is active in the field of environmental protection, wastewater treatment, waste management and development of new methods in determination of environmental and process parameters (environmental metrology). Last year (2010) a patent was filed in the field of sensors for organophosphates, latest major occupation are also high temperature sensors.

C.02 Editorial board of a national monograph
COBISS.SI-ID: 251412480Based on the national award given to the project leader (best researcher) in 2010 (according to industrial companies), several interviews followed in 2011. It was the opportunity to present the Slovenian public our research work and actions on the field of optical chemical sensors.

The lecture covered the filed of quantum dots used in sensor applications. Luminescent sensors are chemical systems that can deliver information on the presence of selected analytes through the variations in their luminescence emission. With the advent of luminescent nanoparticles several new applications in the field of chemical sensing were explored. Among them, quantum dots (QD) represent inorganic semiconductor nanocrystals that are advantageous over conventional organic dyes from many different points of view. In this short review, the optical detection of various analytes using QD-based probes/sensors is presented and significant sensor’s characteristics are discussed.
