“…Over the last decades, nanomaterials have gained more and more attention due to their application potential in different branches of industry, e.g., electronics, photocatalysis, environment protection, and civil engineering (Sikora et al 2016;Lah et al 2018;Kolahalam et al 2019;Markowska-Szczupak et al 2020). Some of them exhibit antimicrobial properties and, therefore, are used to eradicate pathogenic microorganisms.…”

The influence of nanomaterials on pyocyanin production by Pseudomonas aeruginosa

et al. 2022

Pseudomonas aeruginosa is a bacterium producing industrially utile metabolites, such as rhamnolipids, biopolymers, and pigments. Pyocyanin, the most studied example of pigments, is a virulence factor that also shows the potential for application in, e.g., agriculture, anticancer therapy, and energy production. Therefore, potential inhibitors and stimulants of pyocyanin production by P. aeruginosa should be studied, and nanomaterials may cause both effects. The study aimed to examine the influence of zinc oxide and multi-walled carbon nanotubes (pristine or dispersed with alginic acid) on pyocyanin production by P. aeruginosa. First, the influence of different concentrations of nanomaterials (500.00–0.06 µg/mL) on culture optical density and biofilm formation was studied. These results helped select concentrations for further tests, i.e., growth curves and fluorescence measurements. Pyocyanin production was assessed by the chloroform–hydrochloric acid method. SEM analysis was conducted to assess the influence of nanomaterials on the cell's integrity and biofilm structure. Pristine multi-walled carbon nanotubes exhibited a stimulative effect on pigment production when applied in high concentrations (500.00 µg/mL), while dispersed material enhanced the production in lowered dosages (125.00 µg/mL). On the other hand, high concentrations of zinc oxide inhibited pyocyanin production, while minor increased bioproduct production. The research indicates the potential to use nanomaterials as the modulators of pyocyanin production and other metabolites.

“…Usually, both solvent and a reducing agent would act as reductant while the surfactant molecules would influence the interaction and reaction of the metallic element in the system [65][66][67]. For Ag nanowires, EG is usually used as a solvent in the solvo-or hydrothermal synthesis, as it enhances the reproducibility and scalability of the end product (Ag nanowires suspension) [68].…”

The recent interest to nanotechnology aims not only at device miniaturisation, but also at understanding the effects of quantised structure in materials of reduced dimensions, which exhibit different properties from their bulk counterparts. In particular, quantised metal nanowires made of silver, gold or copper have attracted much attention owing to their unique intrinsic and extrinsic length-dependent mechanical properties. Here we review the current state of art and developments in these nanowires from synthesis to mechanical properties, which make them leading contenders for next-generation nanoelectromechanical systems. We also present theories of interatomic interaction in metallic nanowires, as well as challenges in their synthesis and simulation.

“…These nanostructures can either be zero dimensional (nanoparticles) (Grzelczak et al, 2008;Hornyak, 2008), one dimensional (nanowires) (Sugunan et al, 2006), two dimensional (thin films) (Aoki et al, 2005) or three dimensional (arrays, hierarchical structures) (Von Freymann et al, 2010). At nano-scale sizes, materials possess unique size-dependent properties that differ from their bulk, which can be exploited for diverse applications, in electronics (Lah and Zubir, 2018), medicine (Uskoković and Bertassoni, 2010), food (Kumar et al, 2019b), fuel (Chung and Manthiram, 2019), solar cells (Fei et al, 2012), sensors (Zhu et al, 2014), and water treatment (Baruah et al, 2012).…”

Biofouling is a major concern to the maritime industry. Biofouling increases fuel consumption, accelerates corrosion, clogs membranes and pipes, and reduces the buoyancy of marine installations, such as ships, platforms, and nets. While traditionally marine installations are protected by toxic biocidal coatings, due to recent environmental concerns and legislation, novel nanomaterial-based anti-fouling coatings are being developed. Hybrid nanocomposites of organic-inorganic materials give a possibility to combine the characteristics of both groups of material generating opportunities to prevent biofouling. The development of bio-inspired surface designs, progress in polymer science and advances in nanotechnology is significantly contributing to the development of eco-friendly marine coatings containing photocatalytic nanomaterials. The review mainly discusses photocatalysis, antifouling activity, and formulation of coatings using metal and metal oxide nanomaterials (nanoparticles, nanowires, nanorods). Additionally, applications of nanocomposite coatings for inhibition of micro- and macro-fouling in marine environments are reviewed.
