“…Last but not least a further advantage of OFET sensors is that they are highly repeatable. Different active layers such as substituted thiophene-based polymers and oligomers, pentacene, metallophthalocyanines (MPCs) and metalloporphyrins (MPs) have been used in OFETs for nitrobased explosives, 34 ammonia, 35 nitric oxides 36,37 and peroxides 38 detection. [29][30][31] This relevant feature has been achieved by applying a pulsed reverse gate bias after a given exposure.…”

The functioning principles of electronic sensors based on organic semiconductor field-effect transistors (OFETs) are presented. The focus is on biological sensors but also chemical ones are reviewed to address general features. The field-induced electronic transport and the chemical and biological interactions for the sensing, each occurring at the relevant functional interface, are separately introduced. Once these key learning points have been acquired, the combined picture for the FET electronic sensing is proposed. The perspective use of such devices in point-of-care is introduced, after some basics on analytical biosensing systems are provided as well. This tutorial review includes also a necessary overview of the OFET sensing structures, but the focus will be on electronic rather than electrochemical detection. The differences among the structures are highlighted along with the implications on the performance level in terms of key analytical figures of merit such as: repeatability, sensitivity and selectivity.

“…With the aid of a hydroxy-terminated polymer surface it was possible to obtain self-assembled mono-layers of the chlorosilane-functionalized semiconductor with comparable electrical performance as for the inorganic substrate. The same SAM-semiconductor has also been used to build ultra sensitive sensors upon which an analyte, binding to the top of a semiconductor mono-layer surface, has a much higher influence on the semiconducting performance than on top of a bulk semiconductor layer [3]. …”

The concept of self-asssembling monolayer formation of organic semiconductors using highly reactive chlorosilane linker groups has been extended to the phosphonic acid linker which can be handled in air. A first proof of concept using an oxidized Al-gate electrode to form a hybrid thin dielectric resulted in a low voltage field effect transistor with hole mobilities of 10 -5 cm 2 /Vs.PEDOT based hole-transport and conductive materials have been improved for use in organic photovoltaics and wide area devices that require Ag busbars. A novel etchant can provide an invisible pattern for conductive transparent electrodes comprised of Clevios™ PEDOT:PSS.

“…For example, Manno et al reported the chemiresistive NO sensor composed of Langmuir-Blodgett films of meso, meso'-buta-1,3-diyne-bridged Cu(II) octaethylporphyrin dimer [18]. Andringa et al reported NO gas sensor based on field-effect transistors modified with iron(III) tetraphenylporphyrin chloride [19]. Meyerhoff et al reported optical sensors composed of indium(III) octaethylporphyrin within ultrathin polymeric films for optical sensing of amine vapors by utilizing dimer-monomer equilibrium reaction [20,21].…”

We report on an optical nitrogen oxide (NO) gas sensor device using cobalt tetraphenylporphyrin (CoTPP) dispersed in three kinds of hydrophobic polymer film matrix (polystyrene (PSt), ethylcellulose (EC), and polycyclohexyl methacrylate (PCHMA)) to improve humidity resistance. Our approach is very effective because it allows us to achieve not only high humidity resistance, but also a more than sixfold increase in sensitivity compared with CoTPP film due to the high dispersion of CoTPP in the polymer film. The limit of detection was calculated as 33 ppb for the CoTPP-dispersed EC film, which is lower than that of CoTPP film (92 ppb).
