We present a novel, portable sensor platform that enables concurrent monitoring of surface mass and charge density variations at thin biointerfaces. This platform combines a coplanar-gated field-effect transistor (FET) architecture with grating-coupled surface plasmon resonance (SPR), yielding an integrated disposable sensor chip prepared by nanoim...
The optically tuneable nature of hybrid organic/inorganic heterostructures tailored by interfacing photochromic molecules with 2D semiconductors (2DSs) can be exploited to endow multi‐responsiveness to the exceptional physical properties of 2DSs. In this study, a spiropyran‐molybdenum disulfide (MoS2) light‐switchable bi‐functional field‐effect tra...
Materials combining stretchability and sensitivity to external stimuli are key for wearable electronics applications to enable the emergence of disruptive technologies in biosensing, health monitoring, photodetection and human motion recognition. Conductive organohydrogels have gained significant attention due to their high sensitivity and cost‐eff...
Molybdenum ditelluride (MoTe2) nanosheets have displayed intriguing physicochemical properties and opto-electric characteristics as a result of their tunable and small band gap (Eg ∼ 1 eV), facilitating concurrent electron and hole transport. Despite the numerous efforts devoted to the development of p-type MoTe2 field-effect transistors (FETs), th...
A robust electrolyte-gated organic field-effect transistor (EGOFET) able to respond to pH in the range 1–10 is reported. This is realized by exploiting the pH-dependent supramolecular host–guest complexation of imidazole/β-cyclodextrin (β-CD). The sensing protocol is performed by incubating magnetic nanoparticles functionalized with β-CD with imida...
The use of blends of small molecule organic semiconductors (OSCs) with insulating binding polymers has shown to be a promising route to facilitate the processing of OSCs over large areas...
Electrolyte-gated organic field-effect transistors (EGOFETs) are promising devices for the development of bio-sensors. Typically, a gold gate electrode is functionalised with a self-assembled monolayer bearing the bio-receptor. Here, we propose...
The deposition of organic semiconductors (OSCs) using solution shearing deposition techniques is highly appealing for device implementation. However, when using high deposition speeds, it is necessary to use very concentrated OSC solutions. The OSCs based on the family of dinaphtho[2,3-b:2',3'-f]thieno[3,2-b]thiophene (DNTT) have been shown to be e...
The implementation of organic semiconductor (OSC) materials in X-ray detectors
provides exciting new opportunities for developing a new generation of
biocompatible devices with high potential for the fabrication of sensitive and
low-cost X-ray imaging systems. Here, the fabrication of high performance

Herein, we report on the synthesis and structural characterization of novel charge transfer (CT) complexes of the benzothienobenzothiophene derivative C8O-BTBT-OC8 with the series of FxTCNQ derivatives (x= 2,4). The degree...
The stability of organic semiconductors (OSCs) is strongly hampered by the presence of water molecules. One approach that has been proved to lead to organic field-effect transistors with an enhanced performance is the use of blends of OSCs with insulating binding polymers. In this work, the fabrication of OSC thin films based on polymeric ternary b...
Here, we study the temperature-dependent transport properties of OFETs with the prototypical OSC 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) co-processed with polystyrene (PS) as the active layer. The active layer is deposited directly on SiO2 using the bar-assisted meniscus shearing (BAMS) method. The co-processing with PS favors...
Molecular surfactants, which are based on a water-insoluble tail and a water-soluble head, are widely employed in many areas, such as surface coatings or for drug delivery, thanks to their capability to form micelles in solution or supramolecular structures at the solid/liquid interface. Electrolyte-gated organic field-effect transistors (EGOFETs)...
Thin films of the organic semiconductor Ph-BTBT-10 and blends of this material with polystyrene have been deposited by a solution shearing technique at low (1 mm s-1) and high (10 mm s-1) coating velocities and implemented in organic field-effect transistors. Combined X-ray diffraction and electrical characterisation studies prove that the films co...
The molecule 2-decyl-7-phenyl-[1]benzothieno[3,2-b][1]benzothiophene (Ph-BTBT-10) is an organic semiconductor with outstanding performance in thin-film transistors. The asymmetric shape of the molecule causes an unusual phase behavior, which is a result of a distinct difference in the molecular arrangement between the head-to-head stacking of the m...
Water‐gated organic field‐effect transistors (WGOFETs) are expected to have a strong impact in the field of electronic biosensors owing to the synergism between the transduction function of the transistors with the fact that they can be operated in physiological media. Nonetheless, a limited library of gate electrodes has currently been explored fo...
Organic semiconductor materials exhibit a great potential for the realization of large-area solution-processed devices able to directly detect high-energy radiation. However, only few works investigated on the mechanism of ionizing radiation detection in this class of materials, so far. In this work we investigate the physical processes behind X-ra...
Despite the recent encouraging advances in achieving high‐performance organic field effect transistors employing meniscus‐guided processing techniques compatible with roll‐to‐roll manufacturing, there is still a very limited knowledge about how all the coating parameters influence the thin film electrical characteristics. Here, the polymorphism and...
The polymorphism and morphology of organic semiconductor thin films blended with insulating polymer deposited by solution shearing techniques were investigated in-depth by modifying shearing parameters and ink formulation. It was found that the structure-composition-properties relationship is essential to produce high performance robust semiconduct...
The functionalisation of the gate electrode in electrolyte-gated field effect transistors (EGOFETs) with self-assembled monolayers effect the device electrical performance mainly due to the induced capacitance changes.
The charge transport in organic semiconductors (OSCs) is ruled by non covalent intermolecular interactions, hence, the control of growth and nucleation is essential. OSCs could exhibit different packing arrangements usually characterized by diverse morphologies which in turn result in different electrical performance. Understanding the structure-pr...
Organic semiconductors (OSCs) are promising materials for cost-effective production of electronic devices because they can be processed from solution employing high-throughput techniques. However, small-molecule OSCs are prone to structural modifications because of the presence of weak van der Waals intermolecular interactions. Hence, controlling t...
