Ag NPs obtained at room temperature (S1) and under optimal microwave irradiation (S2) were compared in the present work. The as-synthesized Ag NPs are characterized by Ultraviolet-Visible (UV-Vis) spectroscopy, X-Ray Diffraction (XRD), Fourier Transform Infrared (FT-IR) spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) and Transmission Electron Microscopy (TEM). UV-Vis spectra showed Surface Plasmon Resonance (SPR) peaks at 430 nm (S1) and 438 nm (S2) associated with the formation of Ag NPs. XRD patterns indicate the crystallinity of Ag NPs, with an average crystallite size of approximately 23 nm (S1) and 15 nm (S2). FT-IR study revealed potential biomolecules to form Ag NPs. FESEM and TEM analysis revealed the spherical shape of Ag NPs. An average particle size of approximately 31 nm (S1) and 19 nm (S2) was revealed from TEM analysis. To the best of our understanding, this study is novel as Ag NPs synthesized from SP using a microwave oven are described in detail for the first time. The study also demonstrated the potential of Ag NPs for antibacterial effect against Gram-positive bacteria (<em>Streptococcus pneumoniae</em>, <em>Staphylococcus aureus</em>) and Gram-negative bacteria (<em>Klebsiella pneumoniae</em>, <em>Vibrio vulnificus</em>).

The pure strain of the bacterium was identified as a potential nanoparticle producer based on its ability to reduce silver ions to nanoparticles. The formation of silver nanoparticles was confirmed by characteristic colour changes and further confirmed by UV–visible spectroscopy with SPR around 415 nm. The synthesized silver nanoparticles were characterized using various techniques, including TEM, SEM and DLS. DLS confirmed the nano-size, homogeneity and good stability of the fabricated particles TEM analysis revealed the spherical morphology of the nanoparticles, with an average size of 50 nm. SEM analysis also confirmed and supported the data. The antioxidant activity of the green-synthesized silver nanoparticles was evaluated using standard assays, and results demonstrated significant antioxidant potential, indicating the ability of the nanoparticles to neutralize free radicals and protect against oxidative stress. The bio-synthesised silver nanoparticles were also tested for their antifungal properties against two clinically relevant fungal strains. Resazurin-based micro-dilution viability assays, agar well diffusion, and spread plate assay methods were employed to determine the MIC and MBC of the nanoparticles, assessing their inhibitory effects on fungal growth. The results revealed potent antifungal activity, with varying degrees of efficacy against the tested fungal pathogens. Besides bioactivity, the cytotoxicity of the nanoparticles was also evaluated using primary cell cultures of peripheral blood cells. The bio-fabricated structures exhibited minimal toxicity and mortality, indicating their benign and eco-friendly nature in biological systems.

The composition of the lipids used in the liposome structure played a crucial role in the solubility of the encapsulated drug. The relatively good solubility of propranolol allowed for its better entrapment within the aqueous part of the liposomes. The encapsulation of propranolol hydrochloride within liposomal coatings is expected to improve the stability of the drug in the body and significantly reduce its release until it reaches the target organ.

Controlled assembly and patterning offer many advantages for the technological development of photovoltaics, optics, and lab-on-a-chip, where the ordering of particles can influence the properties and functions of a system. Many techniques have been well established for patterning ordered colloidal arrays (colloidal crystals), and disordered colloidal arrays (colloidal glasses). However, they are time-consuming and require additional steps such as masking, etching, or stamping. The advent of digital manufacturing, in which additive manufacturing is combined with computer-aided design (CAD), can overcome some of the challenges in fabricating structures from colloidal particles. This article presents a review of recent strategies for digitally fabricating 1D (e.g., single line), 2D (e.g., arrays of dots and patterns with lines), and 3D (e.g., dots and balls) colloidal crystals and glasses, including inkjet printing, direct ink writing, electrohydrodynamic jet printing, two-photon lithography, and digital light processing. The requirements of colloidal ink formulations for different 3D printing methods are discussed.

The crystal system of the Bi<sub>2</sub>O<sub>3</sub> phase is hexagonal. After annealing at 500 °C, not only morphological changes occurred in the studied composite, but also significant transformations in the microstructure. In the film volume, oxide phases Ti<sub>2</sub>O<sub>3</sub> and Bi<sub>2</sub>O<sub>3</sub> began to transform into three-component compound Bi<sub>4</sub>Ti<sub>3</sub>O<sub>12</sub>, and this process is completed at 700 degrees with the formation of single-phase Bi<sub>4</sub>Ti<sub>3</sub>O<sub>12</sub> nanocomposite with an orthorhombic lattice with the crystal space group <em>Fmmm</em>.</p></div>","PeriodicalId":100959,"journal":{"name":"Next Nanotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949829523000384/pdfft?md5=f45f50cbdf9aeaf05afae3adb5b1f518&pid=1-s2.0-S2949829523000384-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139100807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
