Recent Advances in Field‐Effect Transistor‐Based Biosensors for Label‐Free Detection of SARS‐CoV‐2

“…[ 176 ] Compared to antibodies, MIPs are not only specific to the target analyte but are also more stable and reproducible. [ 177 ] Parlak et al [ 67 ] developed an OECT to achieve selective sensing of cortisol in human sweat. An MIP‐based artificial recognition membrane was interposed between the PEDOT:PSS channel layer and analyte (sweat) reservoir.…”

Solution-processed filamentous copper phthalocyanine films for enhanced NO2 gas sensing at room temperature

“…Organic field effect transistor (OFET) gas sensors, as a new generation of gas sensors, not only have the characteristics of a simple preparation process, low cost, light weight and good flexibility, but also have the outstanding characteristics of rapid start-up at room temperature, sensing and high amplification, simple portability, high sensitivity and intelligent electronic applications. [1][2][3] Organic semiconductors (OSCs) are the key component of OFETs, which directly affect the performance and application field of OFETs. [4][5][6] For OFETs, the conducting channels are usually concentrated within a few molecular layers at the bottom of the OSCs, near the interface between the OSCs and the dielectric layers.…”

Evaluating mobility extraction reliability in non-ideal organic transistors utilizing weak epitaxy-grown pentacene films

“…Organic thin-film transistors (OTFTs) have garnered significant attention as promising candidates for wearable, flexible and large area electronics [1][2][3][4][5][6][7][8][9][10][11][12]. Recently, carrier mobility in OTFTs has surpassed the benchmark of 10 cm 2 Vs −1 through the synthesis of novel organic semiconductor materials and the refinement of device * Author to whom any correspondence should be addressed.…”
