Special Issue Information

Dear Colleagues,

Metallic nanostructures/nano-morphologies have attracted much attention due to their multipurpose electric, magnetic, optic, and thermal properties. These nanostructures/nano-morphologies are important in a specific area due to their morphological structure (zero-dimensional (0D), one-dimensional (1D), two-dimensional (2D), and three-dimensional (3D)) and their uses in catalysis, photonics, chemobiological, and sensor development. Silver (Ag) possesses the highest electrical and thermal conductivity among all metals. Further, its nanostructures/nano-morphologies have attracted substantial attention. Zero-dimensional silver nanomaterials can be used in optical, chemical, and biological sensor designing, while 1D silver nanomaterials (nano-wires, nano-tubes, nano-ribbons, and nano-belts) can be used in energy, devices, and security. In contrast, 2D silver nanomaterials exist in the form of nano-prisms, nano-disks, nanoplates, nano-sheets, and nano-walls. Three-dimensional silver nanomaterials are widely used in magnetic and electrodes as energy storage devices. Silver is well recognized due to its plasmonic properties in the visible range. The performance of nanomaterials strongly depends on their size, shape, and dimensionality (0D, 1D, 2D, 3D). Thus, there is a need to synthesize silver morphologies (0D, 1D, 2D, 3D) in a controlled way, without any impurities, so that their utilization can have a large number of positive effects instead of adverse effects.

In this Special Issue, we wish to cover advances in controlling the morphologies of silver (Ag) structure, synthesis, multiapplication, and the investigation of morphologies with advanced analytical techniques. I am pleased to invite your full research articles and review papers.

Biogenic nanoparticles are considered effective alternatives to chemical pesticides for the management of pathogenic plant diseases. This study was focused on the synthesis of stable silver nanoparticles (AgNPs) to control challenging plant pathogenic bacteria in vitro and in planta. We synthesized AgNPs by reacting different proportions of silver nitrate and aqueous extract of Hedera nepalensis. The physicochemical properties of the synthesized AgNPs were determined by using various physical techniques. The TEM analysis revealed the AgNPs less than 50 nm in size and spherical shaped. For antibacterial assays, different concentrations (1000–15.62 µg/mL, 2-fold dilutions) of the extract-free AgNPs (Ef-AgNPs) or extract-mixed AgNPs (Em-AgNPs), and fruit extracts (FE) were used against plant pathogenic bacteria Erwinia carotovora subsp. carotovora, Erwinia carotovora subsp. atroseptica, and Ralstonia solanacearum. In the in vitro assays, we found significant inhibition of both bacterial species in response to maximum concentrations of AgNPs. Overall, Ef-AgNPs exhibited a higher percent inhibition of bacterial pathogens. In potato tubers assay, complete inhibition of Erwinia carotovora was observed, except for the lowest AgNPs concentration of 15.62 µg/mL. Similarly, exposure of tomato plants to Ralstonia solanacearum suspensions (OD600 = 0.2) in the soil-drenching experiment and post-exposure treatment with 1000 µg/mL and 125 µg/mL of AgNPs resulted in disease inhibition. This study provides the basis that biogenic nanoparticles prepared from Hedera nepalensis are one of the best substitutes to synthetic pesticide, having displayed better results to control the growth of phytopathogenic microbes. However, field studies need to be conducted in a controlled environment to scale up the current work and find out the efficacy of nanoparticles on a larger scale. Full article

This research provides a sustainable way to treat water by removing heavy metal hazards (mercury ion) and biological pollutants (several strains of bacteria and fungi) through the eco-friendly synthesis of silver nanoparticles using the ethanol extract of the Saudi Haloxylon ammodendron shrub, which is planted in the Qassim desert. Further, this work confirms that these nanoparticles could be used as anticancer materials. The optimization factors of the biosynthesis of silver nanoparticles were studied and obtained (volume ratio = 1:2, pH = 7.5, and temperature = 60 °C). The scanning electron microscope micrographs showed the spherical shape and the huge numbers of silver nanoparticles accumulated, while X-ray diffraction measurements gave the crystal size of these nanoparticles in the range of 10.64 nm. The application findings of these biofabricated silver nanoparticles demonstrated effective detection and removal of different concentrations of mercury ions (0–2500 ppm) from the polluted aqueous solutions. The work revealed that Haloxylon ammodendron extract enhanced the antibacterial and antifungal activities of silver nanoparticles against different strains of bacteria and fungi. As well, the anticancer activity examinations of these nanoparticles and the extract showed good and reasonable results. Full article
