OPTO-ELECTRONIC SYSTEM WITH OPTICAL FIBRES SENSOR FOR IONIC CONCENTRATION MEASUREMENT INTO SANGUINE SERUM

摘要

The paper presents an opto-electronic system with optical fibres sensor for ionic concentration measurement into sanguine serum. The performed study describes the behaviour of a fluorescence marker (fluorescein) into sanguine serum in the presence of hydrogen, calcium, magnesium and sodium ions. These studies can emphasise the marker selectivity under different conditions. Another important advantage of the measurement system is that it is very flexible, which allows very diverse studies in this domain, including the adaptation for sensors with selective-permeable membranes. Obviously, the study will be continued in order to observe also the influence of red cells from blood (the main suspect of the values dispersion), as others measurements. Also the performed system showed that it can be used for the subsequent studies concerning the behaviour of the others fluorescence markers, as in the tampon chemical solutions and in the complex organic solutions, like sanguine serum.
