“…1a and b) with a production scale-up factor between 150 and 300 times and yet of comparably narrow size distribution as those previously reported in the literature424344. In a typical synthesis, our method yields 20 times more AgNPs also with respect to the approach recently reported by Zhang and coworkers45. After synthesis, the AgNPs were concentrated by centrifugation and coated by polyvinylpyrrolidone (PVP) of relatively low molecular weight (10 kDa).…”

Printed polymer electronics has held for long the promise of revolutionizing technology by delivering distributed, flexible, lightweight and cost-effective applications for wearables, healthcare, diagnostic, automation and portable devices. While impressive progresses have been registered in terms of organic semiconductors mobility, field-effect transistors (FETs), the basic building block of any circuit, are still showing limited speed of operation, thus limiting their real applicability. So far, attempts with organic FETs to achieve the tens of MHz regime, a threshold for many applications comprising the driving of high resolution displays, have relied on the adoption of sophisticated lithographic techniques and/or complex architectures, undermining the whole concept. In this work we demonstrate polymer FETs which can operate up to 20 MHz and are fabricated by means only of scalable printing techniques and direct-writing methods with a completely mask-less procedure. This is achieved by combining a fs-laser process for the sintering of high resolution metal electrodes, thus easily achieving micron-scale channels with reduced parasitism down to 0.19 pF mm−1, and a large area coating technique of a high mobility polymer semiconductor, according to a simple and scalable process flow.

“…In the spectrum of WPU, there was no obvious diffraction peak and only a scattering peak appears at around 20 , which was probably due to the amorphous structure, small crystalline structure or diffraction from large crystals. 24 By contrast, the WPU/Ag-4 nanocomposite appeared to possess unique peaks at 38 , 44 , 64 and 77 , corresponding to the (111), (200), (220) and (311) planes of the face-centered cubic silver nanoparticles, respectively. 25…”

“…30 Besides, the metal-organic complexation effect of AgNPs may be another reason for the enhancement in mechanical properties. 31 Meanwhile, unfortunately, the elongation at break decreased, indicating the compromise of the exibility and ductility of lm materials. An enhanced cross-linking density enhances the tensile strength but drops the elongation at break.…”

“…Even stable silver nanoclusters have been used for the detection of aluminum ions [30]. Silver nanoparticles coated with citrate or polyvinylpyrrolidone (PVP) were demonstrated to be versatile due to their different applications in a wide variety of fields like electronic applications or cell imaging between others [31][32][33].As reported in the literature, the use of metallic nanoparticles as a detection system for metal ions is based on the shift to longer wavelengths of the surface plasmon resonance (SPR) absorption band due to the presence of metallic ions. However, deconvolution analysis can be a powerful tool for characterizing the interaction band between metallic nanoparticles and molecules in solution.…”

The use of silver nanoparticles stabilized with citrate and polyvinylpyrrolidone as a sensor for aluminum ions determination is proposed in this paper. These non-functionalized and specific nanoparticles provide a highly selective and sensitive detection system for aluminum in acidic solutions. The synthesized nanoparticles were characterized by transmission electron microscopy. Surface plasmon band deconvolution analysis was applied to study the interaction between silver nanoparticles and aluminum ions in solution. The interaction band in the UV-visible region was used as an analytical signal for quantitation purposes. The proposed detection system offers an effective AND wide linearity range (0.1-10 3 nM), specificity for Al(III) in THE presence of other metallic ions in solution, as well as high sensitivity (limit of detection = 40.5 nM). The proposed silver-nanoparticles-based sensor WAS successfully used for detecting Al(III) in real water samples.Materials 2020, 13, 1373 2 of 15 aluminum ions through which Al(III) enters the human food chain; plant roots are also adversely affected by the release of Al(III) ion from the acidic soil [11][12][13].Considering the strong impact of aluminum on human health and the environment, Al(III) detection is important. Analytical techniques commonly used for detecting metal ions include ion selective electrodes [14], electrochemical methods [15], atomic absorption and emission spectrometry [16,17], and colorimetric sensors [18,19].Metallic nanoparticles were proposed as colorimetric sensors for numerous metal ions in different kind of samples. Gold nanoparticles (AuNPs) as well as silver nanoparticles (AgNPs) have been used for these purposes [20][21][22][23][24][25][26]. Usually, AuNPs and AgNPs are functionalized to obtain specific and selective sensors for detecting the desired metallic ion. Chen et al. used triazole-ether functionalized gold nanoparticles for the colorimetric detection of Al(III) ions [27]. Citrate-capped gold nanoparticles were used for rapid visual detection of aluminum at concentrations down to 1.0 µM [18]. Ascorbic-acid-capped gold nanoparticles were used for the selective colorimetric detection of aluminum ions in ground water [28]. Liu et al. proposed a colorimetric assay for Al(III) based on alizarin red S-functionalized silver nanoparticles [4]. Silver nanoparticles stabilized by reduced glutathione (GSH-AgNPs) in the presence of L-cysteine were used for colorimetric detection of aluminum by Yang et al. [29]. Even stable silver nanoclusters have been used for the detection of aluminum ions [30]. Silver nanoparticles coated with citrate or polyvinylpyrrolidone (PVP) were demonstrated to be versatile due to their different applications in a wide variety of fields like electronic applications or cell imaging between others [31][32][33].As reported in the literature, the use of metallic nanoparticles as a detection system for metal ions is based on the shift to longer wavelengths of the surface plasmon resonance (SPR) absorption band due to the pr...
