In this review, we provide an overview of conjugated organic semiconductors and their applications in biological sensing with a primary focus on the role semiconductor.
Over the last decade, organic electrochemical transistor (OECT) has appeared as a powerful platform for developing bioelectronic applications such electronic biosensors and neuromorphic devices. The rapidly growing interest in this field spurred development of new active materials that are tailor-made to fulfil mixed ionic-electronic conduction requirements OECT. While p-type (hole-transporting) semiconductors quickly with impressive properties, their electron-transporting counterparts,...
Organic mixed ionic-electronic conductors (OMIECs) have emerged as promising materials for biological sensing, owing to their electrochemical activity, stability in an aqueous environment, and biocompatibility. Yet, OMIEC-based sensors rely predominantly on the use of composite matrices enable stimuli-responsive functionality, which can exhibit issues with intercomponent interfacing. In this study, approach is presented non-enzymatic glucose detection by harnessing a newly synthesized...
Abstract Introducing ethylene glycol (EG) side chains to a conjugated polymer backbone is well‐established synthetic strategy for designing organic mixed ion‐electron conductors (OMIECs). However, the impact that film swelling has on conduction properties yet be scoped, particularly electron‐transporting ( n ‐type) OMIECs. Here, authors investigate effect of length branched EG charge transport ‐type OMIECs based naphthalene‐1,4,5,8‐tetracarboxylic‐diimide‐bithiophene backbone. Atomic force...
Abstract The development of soft and flexible devices for collection bioelectrical signals is gaining momentum wearable implantable applications. Among these devices, organic electrochemical transistors (OECTs) stand out due to their low operating voltage large signal amplification capable transducing weak biological signals. While liquid electrolytes have demonstrated efficacy in OECTs, they limit its temperature pose challenges electronic packaging potential leakage. Conversely, solid...

Bandgap narrowing due to lanthanide doping acquiring cassiterite...
The sub-Terahertz and Terahertz bands play a critical role in next-generation wireless communication sensing technologies, thanks to the large amount of available bandwidth this spectral regime. While long-wavelength (microwave mm-Wave) short-wavelength (near-infrared ultraviolet) devices are well-established studied, sub-THz THz regime remains relatively underexplored underutilized. Traditional approaches used aforementioned regions more difficult replicate band, leading need for...
This work investigates the changes in mechanical properties of glycolated polythiophenes induced by electrochemical addressing and electrolyte concentration, due to its ability stabilize water.
Organic thermoelectric (TE) attracts considerable interest as a next-generation energy conversion technology; however, its practical application is still restricted by low power factors. Herein, we report generally applicable solvent-combination doping method for improving TE properties of conjugated polymers (CPs). Residual solvents in ternary solvent enlarged the free volume CP films. This beneficial effect boosted both dopant diffusion efficiency and charge carrier density doped films,...

Abstract A rapidly growing interest in organic bioelectronic applications has spurred the development of a wide variety mixed ionic‐electronic conductors. While these new conductors have enabled community to interface electronics with biological systems and efficiently transduce signals (ions) into electronic signals, current materials selection does not offer sufficient selectivity towards specific ions relevance without use auxiliary components such as ion‐selective membranes. Here, we...
In the past decade, organic mixed ion-electron conductors have been successfully adopted in innovative bioelectronic, neuromorphic, and electro-optical technologies, as well multiple energy harvesting printed electronics applications. However, despite intense research efforts devoted to these materials, not yet found application electronic/photonic devices operating key regions of electromagnetic spectrum, such microwave (>5 GHz) terahertz (0.1-10 THz) ranges. A possible reason for this...

Abstract Poly(3,4‐ethylenedioxythiophene) ( PEDOT ) is a well‐known semiconducting polymer with favorable properties which find it often applied as the active material in biological sensors and electrochromic devices. However, has several drawbacks can prohibit its effective or long‐term use, including weak adhesion to substrates such ITO‐coated glass, poorly controlled surface morphology, reduced electrochemical stability over time. While diverse range of approaches have been explored...

Abstract Although p-type organic mixed ionic electronic conductors (OMIECs) are susceptible to oxidation, it has not yet been considered as whether oxygen could behave an uncontrolled p-dopant. Here, dissolved in solvents is shown be a p-dopant, that fills traps enable more effective electrochemical doping OMIECs and transistors (OECTs). Yet the presence of also jeopardizes OECT stability. A two-step strategy introduced solve this contradictory problem, where first solvent degassed, second...
