  Synthesis, characterization, and antibacterial activity of silver nanoparticles with expired minocycline as reducing agent: proposed as a recycling technique

  By Othman O. Dakhil1,*, Islam Altalhy, Mohamed A. Sharkasi, Ruwida M. K. Omar, Yousra Fathi

  Abstract: In this research, expired minocycline, a broad-spectrum tetracycline antibiotic, was employed as both a reducing and stabilizing agent for the eco-friendly synthesis of silver nanoparticles. This sustainable method avoids the use of toxic chemical reducing agents, providing a greener alternative for nanoparticle production. The synthesized silver nanoparticles were analyzed using several characterization techniques, such as UV-Vis’s spectroscopy, scanning electron microscopy, transmission electron microscopy, and Edex analysis, to assess their structural, …

  Au@Sio2@PVP-DCMD Membranes: A Breakthrough in Heavy Metal Removal and Antibacterial Defense

  By Sufyana Idrees, Aneeqa Sabah, Mohsin Nazir, Whied ul Hussan Shahzad, Aneela Sabbir, Sahar Tasleem

  Abstract: This study investigates the development and characterization of multifunctional gold-doped silica (Au@SiO₂) membranes for water distillation and antibacterial applications. The manufacturing process integrated gold nanoparticles into silica matrices using sol-gel techniques. Structural analysis was conducted using SEM (showing uniform pore distribution with an average pore size of 40-50 nm), FTIR (confirming Si-O-Si and Si-Au-Si bonding peaks at 525 cm⁻¹ and 1310 cm⁻¹ respectively), EDX (revealing gold nanoparticle content of 1.5 …
