In this work, a microfluidic system to investigate the flow behavior of red blood cells in microcirculation-mimicking network PDMS microchannels with thickness comparable cell size is presented. We provide first quantitative description velocity and shape as function applied pressure drop such devices. Based on these results, novel methodology measure membrane viscoelastic properties converging/diverging developed, results are good agreement data from literature. particular, diverging...
N-type organic field-effect transistors (OFETs), based on two perylene diimide semiconductors (PDI-8 and PDI-8CN2) exhibiting very different air sensitivities, have been fabricated Si/SiO2 substrates. These OFETs electrically characterized in vacuum both the dark under white-light illumination by dc transfer output curves, bias stress experiments variable temperature measurements. In particular, combination of light is shown to be a powerful tool clarify influence charge trapping device...
Three novel diketopyrrolopyrrole (DPP) based small molecules have been synthesized and characterized in terms of their chemical-physical, electrochemical electrical properties. All the consist a central DPP electron acceptor core symmetrically functionalized with donor bi-thienyl moieties flanked terminal positions by three different auxiliary electron-acceptor groups. This kind molecular structure, an alternation groups, was purposely designed to provide significant absorption at longer...
Abstract MXene‐based materials have gained attention in the biomedical field due to their promising biocompatibility, improved mechanical strength, and conductivity. In this study, focus is on optimizing MXene‐incorporated electrospun fibers subsequent characterizations assess potential for applications. Polyvinyl alcohol (PVA) used as appropriate matrix material process parameters are finetuned ensure effective incorporation of MXene. XRD spectroscopic analysis confirm successful synthesis...
Bias stress effects in n-channel organic field-effect transistors (OFETs) are investigated using PDIF-CN2 single-crystal devices with Cytop gate dielectric, both under vacuum and ambient. We find that the amount of bias is very small as compared to all (p-channel) OFETs reported literature. Stressing by applying 80 V for up a week results decrease source drain current only ~1% ~10% air. This remarkable stability leads characteristic time constants, extracted fitting data stretched...
The global COVID-19 pandemic has had severe consequences from the social and economic perspectives, compelling scientific community to focus on development of effective diagnostics that can combine a fast response accurate sensitivity/specificity performance. Presently available commercial antigen-detecting rapid diagnostic tests (Ag-RDTs) are very fast, but still face significant criticisms, mainly related their inability amplify protein signal. This translates limited sensitive outcome...
Here, we report how OECTs can be used for the detection of emulsion microstructural development during a nano-emulsification process realized by gradual addition water to mixture oil and two non-ionic surfactants.
Transglutaminase 2 (TG2) is a ubiquitously expressed member of the transglutaminase family with Ca2+-dependent protein crosslinking activity. Its subcellular localization crucial in determining its function, and indeed, TG2 found extracellular matrix, mitochondria, recycling endosomes, plasma membrane, cytosol, nucleus because it associated cell growth, differentiation, apoptosis. It involved several pathologies, such as celiac disease, cardiovascular, hepatic, renal, fibrosis diseases,...
A novel, easy, and cost-effective synthetic procedure is reported for the production of very highly regioregular poly[3-(4-alkoxyphenyl)thiophene]s by means oxidative coupling.
