Seof organizing map analysis of the selectivity properties of QMB snesors coated by prophyrin films

摘要

In recent years methalloporphyrins and their derivative have been proposed as sensitive layers for mass variation based transducers for the detection of volatile compoujds. Despite the positive result obtained so far a systematic study of the kinds of interactions ruling tyhe sensing mechanism has not yet been conducted. This paper reports on a study oriented towards a deeper comprehension of such mechanism and it introdues a self organizing map based methodology for the analysis of seletivities.
