Customization of structure, morphology and optical characteristics of silver and copper nanoparticles: Role of laser fluence tuning

Mahmood Alhajj et al.

Summary: The production of high purity silver and copper nanoparticles with desired physical properties was achieved by using the pulsed laser ablation in liquid method. The nanoparticles showed increased UV-Vis absorbance and a blue shift as the laser fluencies varied. The optical band gap energies of the nanoparticles were determined to be within specific ranges, indicating their high purity. TEM and HRTEM images confirmed the nucleation of spherical, homogenous, and crystalline nanoparticles with varying diameters. The obtained pure and spherical silver and copper nanoparticles with customized properties may have potential applications in photovoltaic and photocatalytic fields.

Anticancer and cytotoxicity evaluation of silver-cinnamon nanoshells

A. A. Salim et al.

Summary: Surface functionalized silver-cinnamon nanoshells (Ag-CNSs) were synthesized using PLAL method and characterized. The anticancer effectiveness and cytotoxicity of Ag-CNSs against liver hepatocellular carcinoma cancer (HepG2) and normal (WRL68) cell lines were evaluated. The Ag-CNSs exhibited strong anticancer activity and improved fluorescence and surface plasmon resonance (SPR) absorption.
