“…It was anticipated that altering the concentration of the reducing agent or gold precursor would have an impact on the size of the NPs. 29 In this regard, the augmentation of OA concentration by a factor of 3 (referred to as TOL3X) led to a marginal enlargement in NP size, as observed in the SEM image depicted in Figure 3a. In this particular instance, a film exhibiting a notable degree of organization, characterized by a high level of uniformity in the size distribution of AuNPs with an average particle size of 13 ± 2 nm, is observed.…”

Metallic nanoparticle-based thin films are utilized in a variety of applications, including catalysis, printed electronics, chemical and biological detection, and smart packaging. Due to their outstanding chemical, physical, and optical capabilities, gold nanoparticles (AuNPs) have been widely developed for these uses. AuNP-based thin films and devices have been fabricated using various techniques involving sophisticated manufacturing equipment such as mechanical milling, vacuum-based deposition, and lithography. Such methods are, however, relatively complex and are used only in pricey device applications or on very small samples. In contrast, solutionbased approaches can offer a more straightforward and affordable strategy that can be used for large-scale production. In this study, a simple in situ reduction-based reactive blade-coating technique that is suitable for roll-to-roll production has been developed for the manufacture of AuNP thin films on rigid and flexible substrates. By varying the concentration of the reactants and the solvent systems, we are able to fabricate AuNP thin films in a variety of sizes and forms (morphologies). The AuNP thin film on glass, prepared using our approach, shows preliminary promising results for glucose detection. This approach facilitates the development of flexible and printable AuNP-based platforms with lower manufacturing costs for use in electrical, chemical, and medicinal applications.

“…It is obvious that the heat treatment temperature had a slight effect on the sheet resistance of the sample. The reasons behind this were that the residual ethylene glycol can volatilize at high temperatures, and the contact between the silver nanoparticles formed in situ were closer at high temperatures [37,38]. The electric conductivity of the printed pattern depended on the concentration of reactive ink, the printed layer number, the substrate, and the heat-treatment temperature, among other factors.…”

“…To address these issues, particle-free in situ reactive inks have been recently developed, with great advantages in their simple, low-cost fabrication process and high conductivity using relatively low treatment temperature [30,31,32,33,34,35,36,37,38]. Bidoki et al reported that deposited layers of in situ reactive silver inks exhibited high electrical conductance of up to 1.89 × 10 5 S/m [30].…”

“…Most recently, Lei et al demonstrated that microscale-conductive silver features can be fabricated on the basis of in situ reactive silver inks on various flexible substrate at 90 °C [32]. On the basis of reactive silver inks, different printing methods such as electrohydrodynamic printing [32], microreactor-assisted printing [34], and inkjet printing [30,34,35,36,37,38] have been used to produce highly conductive silver features at relatively low temperatures. However, there are still areas for improvement.…”

We report a fabrication method of the conductive pattern based on in situ reactive silver precursor inks by inkjet printing. The reactive silver precursor inks were prepared with ethylene glycol and deionized water mixture as the solvent, and silver nitrate as silver source. Sodium borohydride solution as the reducing agent was first coated on photographic paper by screen printing process, and then dried at 50 °C for 4 h. Furthermore, the reactive silver precursor inks were printed on a photographic paper coated with sodium borohydride using inkjet printing to form silver nanoparticles in situ due to redox reaction, and thus a conductive pattern was obtained. The effects of the reactive silver precursor ink concentration and printing layer number and treatment temperature on the electrical properties and microstructures of the printed patterns were investigated systematically. The size range of in situ-formed silver nanoparticles was 50–90 nm. When the reactive silver precursor ink concentration was 0.13 g/mL, the five-layer printed pattern exhibited a sheet resistance of 4.6 Ω/γ after drying at room temperature for 2 h; furthermore, the sheet resistance of the printed pattern decreased to 1.4 Ω/γ after drying at 130 °C for 2 h. In addition, the display function circuit was printed on the photographic paper to realize the display of the numbers 0–99. It provides new research ideas for the development of environmentally friendly and low-cost flexible paper-based circuits.
