To develop a benign nanomaterial from biogenic sources, we have attempted to formulate and fabricate silver nanoparticles synthesized from the culture filtrate of an endophytic fungus strain LA-1 (PoAgNPs). The synthesized PoAgNPs were exclusively characterized through UV-vis absorption spectroscopy, Fourier Transform Infra-Red spectroscopy (FT-IR), X-ray powder diffraction (XRD), and Transmission Electron Microscopy (TEM) with energy dispersive X-ray spectroscopy (EDX). The synthesized nanoparticles showed strong absorbance around 430 nm with surface plasmon resonance (SPR) and exhibited a face-centered cubic crystalline nature in XRD analysis. Proteins presented in the culture filtrate acted as reducing, capping, and stabilization agents to form PoAgNPs. TEM analysis revealed the generation of polydispersed spherical PoAgNPs with an average size of 52.26 nm. The PoAgNPs showed excellent antibacterial activity against bacterial pathogens. The PoAgNPs induced a dose-dependent cytotoxic activity against human adenocarcinoma breast cancer cell lines (MDA-MB-231), and apoptotic morphological changes were observed by dual staining. Additionally, PoAgNPs demonstrated better larvicidal activity against the larvae of . Moreover, the hemolytic test indicated that the as-synthesized PoAgNPs are a safe and biocompatible nanomaterial with versatile bio-applications.

Surface-enhanced Raman scattering (SERS) technology has attracted more and more attention due to its high sensitivity, low water interference, and quick measurement. Constructing high-performance SERS substrates with high sensitivity, uniformity and reproducibility is of great importance to put the SERS technology into practical application. In this paper, we report a simple fabrication process to construct dense silver-coated PMMA nanoparticles-on-a-mirror SRES substrates.

In this study, we present the synthesis of a silver nanocomposite by utilizing a β-cyclodextrin (βCD) polymer anchored onto the surface of magnetic g-CN (referred to as g-CN-FeO/βCD-Ag). The structure and composition of the g-CN-FeO/βCD-Ag nanocomposite were thoroughly characterized using various techniques, including FT-IR, FE-SEM-EDS, TEM, TGA, XRD, ICP, and VSM. This catalytic system exhibited excellent selectivity in reducing nitro groups, even in the presence of other reactive functional groups, resulting in high yields ranging from 85 to 98%.

Ensuring everyone enjoys healthy lifestyles and well-being at all ages, Progress has been made in increasing access to clean water and sanitation facilities and reducing the spread of epidemics and diseases. The synthesis of nano-particles (NPs) by using microalgae is a new nanobiotechnology due to the use of the biomolecular (corona) of microalgae as a capping and reducing agent for NP creation. This investigation explores the capacity of a distinct indigenous microalgal strain to synthesize silver nano-particles (AgNPs), as well as its effectiveness against multi-drug resistant (MDR) bacteria and its ability to degrade Azo dye (Methyl Red) in wastewater.

Mercury (Hg) is a global pollutant of concern, and its transport and transformation are controlled by various environmental factors, with aquatic particles being an important driver. Understanding the interactions between silver nanoparticles (AgNPs) and Hg under dark condition is a prerequisite for studying the extent of AgNPs interaction with light and its participation in Hg biogeochemical cycling. Herein, under laboratory experimental setting, it was found that the reduction of divalent Hg (Hg(II)) to gaseous elemental Hg (Hg) by AgNPs readily occurred.

Silver nanoparticles are recognized for potent antimicrobial properties against pathogenic bacteria, crucial in addressing the severity of leptospirosis, where an ideal treatment is lacking. This study focuses on assessing the antimicrobial efficacy of silver-doped zinc oxide nanoparticles (ZnO:9Ag) on standard Leptospira spp. strains (six species and ten serovars).
