Printed, cost-effective and stable poly(3-hexylthiophene) electrolyte-gated field-effect transistors

Abstract

A large-area processable ink-jet-printed poly(3-hexylthiophene) electrolyte-gated field-effect transistor, designed for bioelectronic applications, is proven to be stable for one week of continuous operation.

“…Further on, it was proven that a suitable packaging of the device, foreseeing, for instance, a hydrogel mat put in contact with the channel, can keep the device always in a water environment and hence stable for several weeks. [ 41 ] Hence the stabilization of the semiconductor does not add to the time‐to‐results.…”

“…Details on the printed EGOFETs fabrication and characterization have been reported elsewhere. [41] Gate Biofunctionalization Protocol: The gate electrodes were cleaned by means of sonication in 2-propanol for 10 min and subsequently rinsed with HPLC water, dried with N 2 and then treated for 10 min in ozone cleaner. The gate biofunctionalization protocol, described in details elsewhere, [42] (sulfo-NHS) aqueous solution for two hours at 25 °C.…”

“…The details and the mechanism of the printed P3HT stabilization have been extensively studied and reported elsewhere. [40,41] In Figure 2B a micrograph of the source and drain interdigitated electrodes and of the circular lateral gate are shown. As anticipated, the electrodes are patterned by photolithography on a plastic foil and the channel area of the interdigitated electrodes is covered with an inkjet-printed P3HT film, in a combination of highly parallelazible and cost-effective processes.…”

Nanochips assisted peptide screening for clinical development of CAR-T cell immunotherapy

“…As a part of this fieldnanobiosensors, have shown their efficiency in ultrasensitive detection of low concentrations of biomolecules [16][17][18][19][20][21][22][23][24][25][26] and single cells [27][28][29][30]. While the major focuses in the community are dedicated to the delivery and characterization of new efficient transducer materials for pointof-care biosensors [31][32][33][34], there is a limited number of reports with the clinical applications of such nanodevices [27,[35][36][37][38][39][40]. We attribute it to the necessary complexity of the system, need for a long-term process monitoring, and thus, a stable performance of the sensor.…”
