Silver Nanoparticles (AgNPs): Comprehensive Insights into Bio/Synthesis, Key Influencing Factors, Multifaceted Applications, and Toxicity─A 2024 Update

ACS Omega, Год журнала: 2025, Номер unknown

Опубликована: Фев. 18, 2025

Silver nanoparticles (AgNPs) are widely recognized for their unique optical, electronic, and antibacterial properties, enabling use in biosensing, photonics, electronics, drug delivery, antimicrobial treatments. Green chemistry-based biological synthesis methods offer an eco-friendly alternative to traditional chemical techniques. Among metallic (NPs) metal oxides, those derived from plant extracts exhibit notable medicinal properties. Due exceptional stability low reactivity, AgNPs particularly well-suited various applications. can be synthesized through chemical, physical, or methods, each with distinct benefits challenges. Chemical physical approaches often involve complex purification, reactive reagents, high energy demands, while though slower, provide sustainable solutions. The chosen method strongly influences the stability, size, purity of resulting NPs. This review emphasizes importance selecting appropriate optimize characteristics functionality silver It consolidates research spanning past two decades, including most recent findings 2024. A comprehensive electronic search databases such as PubMed, Scopus, ScienceDirect, Cochrane, Google Scholar was conducted up-to-date overview advances applications nanoparticles.

The Composition of the Dispersion Medium Determines the Antibacterial Properties of Copper (II) Oxide Nanoparticles Against Escherichia coli Bacteria

Nanomaterials, Год журнала: 2025, Номер 15(6), С. 469 - 469

Опубликована: Март 20, 2025

Copper (II) oxide nanoparticles (CuO NPs) attract much attention as a promising antimicrobial agent. We studied the antibacterial properties of three types CuO NPs against Escherichia coli bacteria: flake-shaped particles with diameter 50–200 nm and thickness 10–20 (CuO-CD synthesized by chemical deposition), spherical size 20–90 (CuO-EE obtained electrical explosion), rod-shaped length 100–200 30 × 70 (CuO-CS commercial sample). tested how shape, size, concentration NPs, composition dispersion medium affected NPs. prepared dispersions based on distilled water, 0.9% NaCl solution, LB broth Lennox used Triton X-100 sodium dodecyl sulfate (SDS) stabilizers. The was 1–100 mg L−1. showed that stabilizer type had greatest influence effects observed maximum effect for all NP dispersed in water without stabilizer, well SDS stabilizer. inhibition culture growth under CuO-EE (by 30%) 1.3–1.8 times depending particles). In saline were minimal; some cases, even promoted bacterial growth. increased but decreased them water. Finally, among particle types, CuO-CS turned out to be most bactericidal, which is probably due their morphology small diameter. At same time, aggregation colloidal systems we did not have linear action properties. These results can development coatings preparations achieve efficiency, taking into account expected conditions use.

Construction and Characterization of Polyethylene Glycol/Sodium Alginate Hydrogel Loaded With Zirconia Nanoparticles: Potential Antibacterial and Antibiofilm Agent to Inhibit Dental Caries In Vitro and In Vivo

Microscopy Research and Technique, Год журнала: 2025, Номер unknown

Опубликована: Март 21, 2025

Biofilm formation on tooth surfaces is a primary contributor to dental caries and periodontal diseases. Streptococcus mutans recognized for its role in biofilm production, significantly influencing the development of caries. Key virulence factors associated with S. biofilms include acid tolerance, synthesis exopolysaccharides (EPS). This study presents novel approach by focusing loading biosynthesized zirconia nanoparticles (ZrO2 NPs) onto polyethylene glycol/sodium alginate (PEG/SA) hydrogel nanocomposite, evaluating their effects biofilm-forming ability both vivo vitro. ZrO2 NPs were using Citrus aurantifolia (C. aurantifolia) extract incorporated into PEG/SA beads through sol-gel process. The PEG/SA/ZrO2 nanocomposite was confirmed diverse analyzes, including UV-visible spectroscopy, particle size measurement, morphology examination, spectral analysis, thermal gravimetric analysis (TGA) hemolysis studies. average approximately 26 nm, while exhibited highly porous, sheet-like surface structure. In vitro results demonstrated inhibition zones 30 28 mm against mutans, respectively, minimum inhibitory concentration (MIC) 12.5 mg/mL. growth curve indicated complete decline an 87% reduction when treated beads. SEM revealed that cells appeared lysed or crumpled, losing characteristic coccal shape after exposure Additionally, images effective prevention attachment teeth encapsulated hydrogel, altering mature developed treatment. Finally, incorporation hydrogels demonstrates significant potential as strategy inhibiting may serve promising topical agent reducing Further studies could explore long-term efficacy clinical applications this oral health care.
