Article Abstract
Dispersed uniform submicron-sized silver spheres were prepared by selective laser heating in the silver-containing precursor solution, which was produced by dissolving the irregular Ag2O in aliphatic amine. By optimizing the process conditions, silver spheres in the range of 578 ± 109 nm were obtained. The smooth surface morphology and solid structure were studied by SEM and TEM. The silver content was characterized by XRD and EDS. Finally, the mechanism of the silver spheres formation was also discussed in detail.

Background: Waning vaccine effectiveness (VE) evaluations are affected by multiple biases, many of which could be implicitly adjusted by using self-controlled methods.
Methods: We used a self-controlled risk interval (SCRI) design to evaluate waning COVID-19 monovalent third dose effectiveness against laboratory-confirmed SARS-CoV-2 medically-attended infections (cases) and hospitalizations with COVID-19 discharge diagnosis among Veterans Health Administration enrollees who received a third dose 15 December 2021-31 August 2022. We used weeks 3-8 post-third dose as reference interval, representing the period of peak VE.

The ultrasound-assisted green synthesis of gold (AuNPs) and silver nanoparticles (AgNPs) from Schinus terebinthifolius extracts delivered stable colloids whose physicochemical properties depend on raw-material preprocessing. Ground sonicated extracts (GSE) produced narrower size distributions and more negative zeta potentials (-19.6 mV for AuNPs, -23.

In this study, a novel nanocomposite was rationally engineered by embedding silver nanoparticles (AgNPs) into tannic acid-derived carbon spheres (Cs), followed by their distribution on graphene oxide (GO) sheets (AgNPs@Cs-TA@GO), aiming to enhance catalytic and antibacterial performance. The fabrication process was expedited using a microwave-assisted technique. The AgNPs@Cs-TA@GO nanocomposite with the core based on AgNPs with an average diameter of 21 nm showed significant peroxidase-like activity by oxidizing 3,3',5,5'-tetramethylbenzidine to its oxidized form in the presence of HO.

Silver nanoparticles (Ag NPs) play a significant role in modern medicine, with their size, shape, and surface chemistry strongly influencing their biological performance. Smaller nanoparticles (1-100 nm) can penetrate cells more easily, while different shapes such as spheres, rods, cubes, triangles, wires, and stars impact their antimicrobial activity and drug delivery efficiency. This review highlights the importance of precise control over these properties during synthesis to optimize their therapeutic potential.

Platelet-rich plasma (PRP) has become an increasingly valuable biologic approach for personalized regenerative medicine because of its potent anti-inflammatory/healing effects. It is thought to be an excellent source of growth factors that can promote tissue healing and lessen fibrosis. Although this treatment has demonstrated effectiveness in numerous disease areas, its impact on pulmonary fibrosis (PF) caused by silver nanoparticles (AgNPs) via its antiapoptotic effects remains to be explored.
