The field of biotechnology has rapidly grown in recent years leading to unprecedent achievements in regenerative medicine and tissue engineering. Among latest high-tech available technologies, 3D bioprinting can be surely considered the most promising to develop complex structures mimicking organs and tissues, as well as functional 3D cell scaffold...
Biomaterials play a crucial role in advancing biosensor technologies for medical, environmental, and food safety applications. This study investigates natural biomaterials, such as food-derived chromophores, cellulose, and peptides, for high-performance biosensors and bioelectronic devices. Chromophores, namely grape anthocyanins, are potential can...
Recent advancements in strain sensor technology are expanding their applications in fields such as soft robotics. A significant advantage would be if these sensors could self-heal completely, especially when damaged in the active area, potentially reducing or completely eliminating maintenance costs. Here, to address this, a self-healable strain se...
This review covers advancements in biosensing, biophotovoltaics, and photobiomodulation, focusing on the synergistic use of light, biomaterials, cells or tissues, interfaced with photosensitive dye-sensitized, perovskite, and conjugated polymer organic semiconductors or nanoparticles. Integration of semiconductor and biological systems, using non-i...
Nanoplastics (NPs) are among the major and most dangerous contaminants in the environment, because of their small size and active surface, which allow them to interact with a variety of other molecules. Current methods used for the detection of NPs rely on bulky and expensive techniques. In this work we propose a novel, fast, and easy-to-use sensor...
Microstrip patch antennas (MPAs) are compact and easy-to-fabricate antennas, widely used in long-distance communications. MPAs are commonly fabricated using subtractive methods such as photolithographic etching of metals previously deposited using sputtering or evaporation. Despite being an established technique, subtractive manufacturing requires...
Carbon nanotubes are a promising sensing material for bio-transduction devices, due to their unique electrical properties, nanosize, bio-compatibility, and their simple low-cost processability. In this contribution, we present two classes of devices (i.e., electrolyte-gated field-effect transistor-based sensors and gas sensors) fabricated by facile...
CNTs based chemiresistive gas sensors are known to not fully recover to the baseline after gas exposure. This is why often heat is applied to thermally activate the sensor and improve the gas desorption process occurring at the surface. In this paper, we combine single-walled CNTs (SWCNTs) with conjugated polymers (CPs) i.e., Poly(3-hexylthiophene)...
The growing usage and consumption of electronics‐integrated items into the daily routine has raised concerns on the disposal and proper recycling of these components. Here, a fully sustainable and green technology for the fabrication of different electronics on fruit‐waste derived paper substrate, is reported. The process relies on the carbonizatio...
Light control of living systems is an emerging field in bioelectronics, in regenerative medicine and cell‐based therapy. Herein, the design of a semitransparent bio–photoelectrolytic platform for control of a neuroblastoma cell line via light pulses is laid out. The platform is based on conjugated polymer films interfaced with a biological electrol...
The recent advances on flexible electronics and sensors have required the development of superior substrates that can withstand different levels and types of deformation, while keeping the integrity and functionality of the sensing materials. This work deals with the development of a zero Poisson's ratio (ZPR) auxetic structure integrated with a pr...
This poster was made on the topic 'Printed heaters for shape memory effect' and was presented in the European Maker Faire 2022 held in Rome, Italy in october 2022. I had joined University of Rome - Tor Vergata who held a stall at the faire and was invited to present a poster at the stall. The work represents the usage of printed thin film heater ma...
Stamping and Patterning of conjugated polymers for Artificial retina devices with spatial and spectral selectivity
The precise monitoring of environmental contaminants and agricultural plant stress factors, respectively responsible for damages to our ecosystems and crop losses, has nowadays become a topic of uttermost importance. This is also highlighted by the recent introduction of the so-called “Sustainable Development Goals” of the United Nations, which aim...
Abstract
Here we propose the use of a diode-based sensor fabricated on a glass substrate coated with an ITO electrode (anode) with a spin-coated semiconducting polymer layer (e.g., Poly(3-hexylthiophene) (P3HT), PCBM) and aluminum counter electrodes (cathode) with a porous structure created by colloidal photolithography. Ammonia molecules can diffu...
Sensing technologies are the basic perception layer of the so called “Agriculture 4.0”. Among the different types of sensing locations for ”Agriculture 4.0”, plant sensors positioned on its surface or inserted directly in the plants could enable an early detection of both biotic and abiotic stresses. Electrical-based approaches like transistor-base...
Additive manufacturing of antennas on three�dimensional (3D) surfaces can reduce material

Thin-film transistors (TFTs) based on amorphous indium-gallium-zinc-oxide (a-IGZO) have proved promising features for flexible and lightweight electronics. To achieve technological maturity for commercial and industrial applications, their stability under extreme environmental conditions is highly required. The combined effects of temperature (T) f...
Since its first discovery in 2014, laser-induced graphene (LIG) has gained increasingly attention as a simple and low-cost alternative to printing techniques, which instead require additional materials such as functional ink or adhesive layers. While there are several works on LIG supercapacitors, gas sensors, and triboelectric generators, this met...
Soft robots, made of deformable and stretchable materials, have been exploited and investigated as promising technologies for a wide range of applications, from human assistance to rehabilitation.
