Eco-friendly biosynthesis of silver nanoparticles by saprophytic Fusarium solani as a sustainable therapeutic approach for the management of methicillin-resistant Staphylococcus aureus wound infections

The rising prevalence of antimicrobial resistance (AMR) has prompted the exploration of novel, naturally sourced therapeutic alternatives. Here, the saprophytic fungus Fusarium solani was used to biosynthesize silver nanoparticles (AgNPs), which were characterized by UV–visible spectroscopy, transmission electron micro...

Chitosan–Antipyrine Schiff Base Nanocomposites With ZnO or Ag Nanoparticles: Synthesis, Characterization, and Dye Adsorption With Preliminary Biological Assessment

A novel chitosan Schiff base derivative (CSB) was synthesized by chemically modifying chitosan with antipyrine. This modified matrix was subsequently used to prepare nanocomposites through the encapsulation of zinc oxide (CSB/ZnO) and silver (CSB/Ag) nanoparticles. Fourier‐transform infrared spectroscopy (FTIR), x‐...

Synthesis, structural elucidation, antimicrobial performance, and DNA-binding behavior of a new N2O2 tetradentate schiff base and its transition metal and uranyl complexes

A new tetradentate N2O2 Schiff base ligand derived from 2,6-diaminopyridine and 2,4-dihydroxybenzaldehyde was synthesized and used to prepare its Cu(II), Co(II), Ni(II), Mn(II), and UO2 (II) complexes. The ligand and complexes were fully characterized by elemental analysis, FT-IR, UV–Vis, 1H/13C NMR, ESR, mass spectrom...
