Abstract Ions are ubiquitous biological regulators playing a key role for vital processes in animals and plants. The combined detection of ion concentration real-time monitoring small variations with respect to the resting conditions is multiscale functionality providing important information on health states. This still an open challenge current sensing approaches. Here we show high-sensitivity complementary organic electrochemical transistors amplifiers. ion-sensing amplifier integrates...
Abstract Ions dissolved in aqueous media play a fundamental role plants, animals, and humans. Therefore, the situ quantification of ion concentration is gathering relevant interest several fields including biomedical diagnostics, environmental monitoring, healthcare products, water food test control, agriculture industry security. The limitation state-of-art transistor-based approaches intrinsic trade-off between sensitivity, range operating voltage. Here we show current-driven configuration...
The detection of protein biomarkers is great importance in the early diagnosis severe pathological states. Although last decade many approaches to achieve ultra-sensitive have been developed, most them require complicated assay set-ups, hindering their adoption point-of-care applications and on-spot diagnosis. Here we show an organic electrochemical transistor (OECT) biosensor printed on plastic substrates that can selectively detect Immunoglobulin G (IgG) with unprecedented attomolar limit....
Abstract Organic electrochemical transistors rely on ionic-electronic volumetric interaction to provide a seamless interface between biology and electronics with outstanding signal amplification. Despite their huge potential, further progress is limited owing the lack of understanding device fundamentals. Here, we investigate organic in wide range experimental conditions by combining electrical analyses modeling. We show that measurements can be quantitatively explained nanoscale charge...
In this paper, a thorough characterization of phase-change memory (PCM) cells was carried out, aimed at evaluating and optimizing their performance as enabling devices for analog in-memory computing (AIMC) applications. Exploiting the features programming pulses, we discuss strategies to reduce undesired phenomena that afflict PCM are particularly harmful in computations, such low-frequency noise, time drift, cell-to-cell variability conductance. The test vehicle is an embedded (ePCM)...
Poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) has been recently proposed for Raman sensing of redox-active species in solution. Here, we investigated the rationale this approach through systematic experiments, which spectrum PEDOT:PSS was analyzed presence either nonoxidizing or oxidizing electrolytes. The results demonstrated that spectra precisely reflect conformation PEDOT units and their interactions with PSS. Two different responses were observed. In case...
Ions are fundamental biological regulators enabling the communication between cells, regulating metabolic and bioenergetic processing playing a key role in pH regulation hydration. The in-situ quantification of ion concentration is gathering relevant interest biomedical diagnostics healthcare. State-of-art transistor-based sensors show an intrinsic trade-off sensitivity, operating range supply voltage. To overcome these limitations, here we focus on sensor amplifiers where complementary...
Biofunctionalized organic transistors have been recently proposed as a simple wide-field single molecule technology.

Here we investigated the rationale of this approach through systematic experiments, in which Raman spectrum PEDOT:PSS was analyzed presence either non-oxidizing and oxidizing electrolytes. The results demonstrated that spectra precisely reflect conformation PEDOT units their interactions with PSS. Two different responses were observed. In case electrolytes, effect charge transfer is accurately transduced changes. On other hand, reduction induces a progressive separation between PSS chains,...
Solution processed Organic Ferroelectric Memory Diodes (OFMDs) are one of the most promising non-volatile memory elements for large area flexible electronics [1] - [4] . In OFMDs it is possible to improve ON/OFF current ratio by orders magnitude simply increasing charge injection barrier [5], [6], at expenses data retention [7]. this work we demonstrate that tune even in case very low barriers, paving way long-missing OFMDs.
