One-pot greener synthesis of silver nanoparticles using tangerine peel extract: large-scale production

In this reported work, superfine silver nanoparticles were synthesised from silver nitrate through a simple, rapid and eco-friendly route applying tangerine extract, which acts as a solvent, reducing agent and stabilising agent simultaneously. The appearance of a darkish brown colour solution is indicative of silver nanoparticles that were confirmed by a UV-vis spectrophotometer. The as-prepared sample was further characterised using X-ray diffraction and energy dispersive X-ray analysis analyses. The morphology and size of the nanoparticles were characterised by scanning electron microscopy and transmission electron microscopy. The silver salt exposing the tangerine extract is reduced and stabilised over long periods of time that results in the green synthesis of silver nanoparticles. The produced nanoparticles were stable over a long period of time and appropriate for applications in biotechnology.
