This perspective deals with the coupling of ionic and electronic transport in organic devices, focusing on electrolyte-gated transistors. These include field-effect transistors (EG-OFETs) electrochemical (OECTs). EG-OFETs, based molecules polymers, can be operated at low electrical bias (about 1 V or below) permit unprecedented charge carrier densities within transistor channel. OECTs aqueous environment as efficient ion-to-electron converters, thus providing an interface between worlds...
Parameter modification and post-synthesis hydrothermal process were applied to tune the size increase bulk order of CNP, resulting in increased photothermal antioxidant activities, without affecting morphological colloidal properties.
The global economic success of man-made nanoscale materials has led to a higher production rate and diversification emission sources in the environment. For these reasons, novel nanosafety approaches assess environmental impact engineered nanomaterials are required. While studying potential toxicity metal nanoparticles (NPs), we realized that gold (AuNPs) have growth-promoting rather than stress-inducing effect. In this study established stable short- long-term exposition systems for testing...
Abstract Background The widespread use of nano-biomaterials (NBMs) has increased the chance human exposure. Although ingestion is one major routes exposure to NBMs, it not thoroughly studied date. NBMs are expected be dramatically modified following transit into oral-gastric-intestinal (OGI) tract. How these transformations affect their interaction with intestinal cells still poorly understood. different chemical nature—lipid-surfactant nanoparticles (LSNPs), carbon (CNPs), surface Fe 3 O 4...
The development of nanocomposite materials for food packaging applications requires a precise balance material functionality, safety, and regulatory compliance. In this work, the design, manufacturing, optimization, feasibility, safety profile polylactic acid (PLA) nanofibers filled with biocompatible carbon nanoparticles (CNP) copper-loaded (CNP-Cu) by electrospinning are presented. To ensure nanoparticle compatibility PLA solvent system achieve uniform dispersion within nanofibers, dynamic...
Innate immune memory is characterized by a modulation in the magnitude with which innate cells such as monocytes and macrophages respond to potential dangers, subsequent previous exposure same or unrelated agents. In this study, we have examined capacity of gold nanoparticles (AuNP), are already use for therapeutic diagnostic purposes, modulate induced bacterial The induction was achieved vitro exposing human primary agents (lipopolysaccharide -LPS-, live Bacille Calmette-Guérin -BCG)...
The widespread and increasing use of nanomaterials has resulted in a higher likelihood exposure by inhalation for nanotechnology workers. However, tracking the internal dose nanoparticles deposited at airways level, is still challenging. To assess suitability particle number concentration determination as biomarker dose, we carried out cross sectional investigation involving 80 workers handling nanomaterials. External was characterized portable counters particles DISCminiTM (Testo, DE),...
Dendritic cells (DCs) shape immune responses by influencing T-cell activation. Thus, they are considered both an interesting model for studying nano-immune interactions and a promising target nano-based biomedical applications. However, the accentuated ability of nanoparticles (NPs) to interact with biomolecules may have impact on DC function that poses unexpected risk unbalanced reactions. Here, we investigated potential effects gold (AuNPs) consequences effector memory in presence...
Nanoparticles in ionic solutions are usually surrounded by stabilizing molecules that avoid aggregation and determine their surface properties, which strongly influence behavior. The present work aims to shed light on the static vs dynamic nature of cetyltrimethylammonium bromide (CTAB) bilayer gold nanoparticles understand its effects nanoparticle evolution biological systems. A systematic study CTAB Au nanorods nanospheres was carried out, exploring role excess free surfactant solution...
Nanoparticles (NPs) show various properties depending on their composition, size, and surface coating, which shape interactions with biological systems. In particular, NPs have been shown to interact immune cells, that represent a sensitive surveillance system of external internal stimuli. this light, in vitro models useful tools for investigating nano-bio-interactions cells different organisms, including invertebrates. work, the effects selected types core size functionalization...
Among particulate matter composing paints, titanium dioxide (TiO2) forms about 20% of the final suspension. Although TiO2 is broadly used in many applications, powders represent an established respiratory hazard for workers with long-term exposure. In 35 a paints production plant (15 exposed and 20 not exposed), we assessed pro-inflammatory cytokines (IL-1β, TNF-α, IL-10, IL-17), surfactant protein D (SP-D) Krebs von den Lungen-6 glycoprotein (KL-6) exhaled breath condensate (EBC). urine...
In the past decades, events occurring at nano-bio interface (i.e., where engineered nanoparticles (NPs) meet biological interfaces such as biomembranes) have been intensively investigated, to address cytotoxicity of nanomaterials and boost their clinical translation. this field, lamellar synthetic model membranes instrumental disentangle non-specific interactions between NPs planar interfaces. Much less is known on nano-biointeractions highly curved interfaces, cubic membranes. These...
Sodium citrate-stabilized gold nanoparticles (AuNPs) are destabilized when dispersed in cell culture media (CCMs). This may promote their aggregation and subsequent sedimentation, or under the proper conditions, interaction with proteins can lead to formation of a NP-stabilizing protein corona. CCMs ionic solutions that contain growth substances which typically supplemented, addition serum, different such as dyes, antioxidants, antibiotics. In this study, impact phenol red,...

Carbon nanomaterials (CNMs) are a heterogeneous class of advanced materials. Their widespread use is associated with human safety concerns, which can be addressed by safe-by design strategies. This implies deep knowledge how physico-chemical properties drive biological effects. The ability CNMs to interact cytochrome
