Dependent on the sensing layer which can be semiconducting polymer, dielectric layer or conducting polymer gate, the PFET sensors can be subdivided into three types. For each type of sensor, we present the molecular structure of sensing polymer, the gas analyte and the sensing performance. Most importantly, we summarize various analyte\u2013polymer interactions, which help to understand the sensing mechanism in the PFET sensors and can provide possible approaches for the sensor fabrication in the future.<\/jats:p>","DOI":"10.3390\/s17010213","type":"journal-article","created":{"date-parts":[[2017,1,23]],"date-time":"2017-01-23T10:40:33Z","timestamp":1485168033000},"page":"213","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":87,"title":["Gas Sensors Based on Polymer Field-Effect Transistors"],"prefix":"10.3390","volume":"17","author":[{"given":"Aifeng","family":"Lv","sequence":"first","affiliation":[{"name":"Physikalisches Institut and Center for Nanotechnology (CeNTech), Universit\u00e4t M\u00fcnster, Wilhelm-Klemm-Str. 10, M\u00fcnster 48149, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yong","family":"Pan","sequence":"additional","affiliation":[{"name":"Physikalisches Institut and Center for Nanotechnology (CeNTech), Universit\u00e4t M\u00fcnster, Wilhelm-Klemm-Str. 10, M\u00fcnster 48149, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lifeng","family":"Chi","sequence":"additional","affiliation":[{"name":"Physikalisches Institut and Center for Nanotechnology (CeNTech), Universit\u00e4t M\u00fcnster, Wilhelm-Klemm-Str. 10, M\u00fcnster 48149, Germany"},{"name":"Jiangsu Key Laboratory for Carbon-Based Functional Materials &amp; Devices, Functional Nano and Soft Materials Laboratory (FUNSOM), Soochow University, Renai Rd. 199, Suzhou 215123, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2017,1,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"343","DOI":"10.1007\/s00216-005-3390-2","article-title":"Chemical and biological sensors based on organic thin-film transistors","volume":"384","author":"Mabeck","year":"2006","journal-title":"Anal.
