Abstract
The aim of this review is to summarize the recent progress in the fabrication of efcient nanostructured polymer-based sensors with special focus on polypyrrole. The correlation between physico-chemical parameters, mainly morphology of various polypyrrole nanostructures, and their sensitivity towards selected gas and volatile organic compounds (VOC) is provided. The different approaches of polypyrrole modication with other functional materials are also discussed. With respect to possible sensors application in medicine, namely in the diagnosis of diseases via the detection of volatile biomarkers from human breath, the sensor interaction with humidity is described as well. The major attention is paid to analytes such as ammonia and various alcohols
Tento souhrnný článek pokrývá nedávné pokroky na poli výroby nanostrukturovaných senzorů plynů a volatilních organických látek na bázi vodivých polymerů se zaměřením na polypyrol. Byly shrnuty fyzikálně-chemické vlastnosti včetně morfologie nanostruktur z polypyrolu a jejich citlivost na vybrané plyny a VOC.
