Abstract

Clean technologies using the principles of green chemistry have attracted the attention of scientists in the last decade. Our work was focused on building advanced silver-based materials using an eco-friendly and convenient method. Two types of silver nanoparticles were synthesized using aqueous extracts of orange (Citrus sinensis) and grapefruit (Citrus paradisi) peels. Hybrid entities consisting of these bionanosilver particles and biomimetic membranes were “green” prepared and studied by spectral methods (UV-Vis absorption and emission, and FTIR-ATR spectroscopy). The morphology of silvercontaining materials was analyzed by AFM images and their physical stability was checked by zeta potential measurements. Also, their antioxidant and antimicrobial properties were evaluated..
