“…Therefore, ξ determination is very important for nano colloids. Due to electrostatic repulsion between each individual NPs, colloids with a large positive/negative ξ value generally indicate good stability [ 9 , 20 ]. A small ξ value indicates the Nps aggregation due to the van der Waals attractive forces, leading to colloidal instability [ 9 , 19 ].…”

“…LaSiS and USP are the techniques often considered for nanoparticle generation under the green synthesis route. Sreenilayam et al (2022) [ 9 ] recently showed that the LaSiS technique operated under batch mode with advanced process control could yield AgNPs size ranging between 27 and 39 nm. Though in the present study, the LaSiS operated under batch mode without any control system produced AgNPs of 45 (±40) nm, the performance of LASiS under recirculatory mode was superior with a significantly smaller size distribution of 12 (±10) nm.…”

“…Cyclo-olefin polymer (COP) with a film thickness of 188 µm (ZeonorFilm ® ZF14–188) was selected for the substrate (Zeon Chemical LP Company, Dusseldorf, Germany). Before printing, the COP surface underwent plasma polymerisation with the plasma chamber opeating at 3 W for 5 s bursts to ensure that it had the necessary hydrophilic surface properties for printing [ 9 ]. The COP was taped onto an 80 g/m 2 printing paper, and 12 Squares of 2 × 2 cm were printed with each square signifying the number of repeat prints on that surface as illustrated in Figure 8 .…”

“…The laser-assisted synthesis (LASiS) technique utilises a high-power laser to ablate metal from a target plate [ 7 ]. The ablated material then condenses to form nanoparticles, resulting in a well-defined colloid [ 9 , 10 ]. In contrast to the LASiS technique, ultrasonic spray pyrolysis (USP) utilises ultrasound to atomise liquid droplets, which are then evaporated and thermally reduced to form the desired nanoparticles [ 8 , 11 ].…”

Food spoilage is an ongoing global issue that contributes to rising carbon dioxide emissions and increased demand for food processing. This work developed anti-bacterial coatings utilising inkjet printing of silver nano-inks onto food-grade polymer packaging, with the potential to enhance food safety and reduce food spoilage. Silver nano-inks were synthesised via laser ablation synthesis in solution (LaSiS) and ultrasound pyrolysis (USP). The silver nanoparticles (AgNPs) produced using LaSiS and USP were characterised using transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, UV-Vis spectrophotometry and dynamic light scattering (DLS) analysis. The laser ablation technique, operated under recirculation mode, produced nanoparticles with a small size distribution with an average diameter ranging from 7–30 nm. Silver nano-ink was synthesised by blending isopropanol with nanoparticles dispersed in deionised water. The silver nano-inks were printed on plasma-cleaned cyclo-olefin polymer. Irrespective of the production methods, all silver nanoparticles exhibited strong antibacterial activity against E. coli with a zone of inhibition exceeding 6 mm. Furthermore, silver nano-inks printed cyclo-olefin polymer reduced the bacterial cell population from 1235 (±45) × 106 cell/mL to 960 (±110) × 106 cell/mL. The bactericidal performance of silver-coated polymer was comparable to that of the penicillin-coated polymer, wherein a reduction in bacterial population from 1235 (±45) × 106 cell/mL to 830 (±70) × 106 cell/mL was observed. Finally, the ecotoxicity of the silver nano-ink printed cyclo-olefin polymer was tested with daphniids, a species of water flea, to simulate the release of coated packaging into a freshwater environment.

Flexible and printed electronics have become increasingly popular as they make possible the production of flexible, low‐cost, multifunction devices that are unachievable through traditional manufacturing methods. The printed films are significantly impacted and thus limited by the existing ink production process. In our work, we have showcased an alternate technique of generating high‐quality titanium dioxide (TiO2) nanoparticle ink compatible with aerosol jet printing (AJP) using laser ablation synthesis in solution (LASiS). Dynamic light scattering (DLS) data and transmission electron microscopy (TEM) confirm the particle size distribution. UV‐vis measurements were performed, and the Beer‐Lambert relationship was used to determine the concentration of the generated ink. We compare the inks generated at two different repetition rates: 200kHz and 1MHz. X‐ray diffraction (XRD) analysis of the aerosol jet printed thin film post thermal sintering confirms the grain size and phase purity of the printed thin films. Our work demonstrates the effectiveness of the LASiS technique in producing printable nanoparticle inks with little to no post‐processing.This article is protected by copyright. All rights reserved.

The development of highly conductive fibril‐type textile electrodes is crucial for the advancement of various smart wearable electronics including high‐performance energy storage devices. To achieve this goal, it is essential to convert insulating textiles into conductive counterparts while maintaining flexibility and porosity. Additionally, the incorporation of electrochemically active components into textile conductors enables tailor‐made textile energy electrodes for specific applications. Thus, textile conductors act not only as conductors but also as energy reservoirs for energy‐active components, providing a facile electron transfer network. However, textile conductors fabricated by most existing methods face challenges such as low conductivity, blockage, and brittleness. One approach to overcome these problems is to utilize interfacial interactions between individual components and textiles. Conductive nanoparticle assembly and electrodeposition based on such rational design result in highly conductive, flexible, and large surface area textile conductors. The subsequent guided assembly of active components creates high‐performance textile energy electrodes. This perspective describes how interfacial interaction‐based assembly can enhance the performance of textile conductors and textile energy electrodes. It also explores various conductor preparation approaches and recent advances in the field for applications in supercapacitors and lithium‐ion batteries.
