A comparative evaluation of green colloidal silver variants for enhanced stability and bioactivity.

ABSTRACT: Colloidal silver (CS) is at the forefront of enhancing novel consumer products formulations & packaging. However, conventional synthesis methods pose challenges, including toxicity, high costs, and poor colloidal stability. Green synthesis using plant extracts offers a sustainable alternative by leveraging natural bioactive compounds. This study compares CS synthesized via a patented plant-based method (CS_BX3), Lemon Juice (CS_LJ), and Green Tea (CS_GT), with a commercial reference (CS_Ref). Characterization using UV-Vis, DLS, SEM, Zeta Potential, and EDS assessed particle size, stability, and composition under stress conditions: long-term storage (60 days), varying temperatures (4-37 °C), pH (3-11), and phosphate-buffered saline (PBS).
