Resumen

The biosynthesis of iron nanoparticles with quinoa leaf extracts represents a breakthrough in green nanotechnology, offering an environmentally friendly method that improves biocompatibility. The objective of the research was the biosynthesis of Fe nanoparticles (NpFe) with quinoa leaf extracts and their respective characterization, through the recognition of functional groups, composition, crystalline structure and morphology of the nanoparticles, using FTIR, X-ray fluorescence, X-ray diffraction and TEM analysis, respectively. Nanoparticles with diameters ranging from 1 to 100 nm and composed of 74.4 % oxygen and 21.1 % iron were obtained, presenting an amorphous structure influenced by the plant matrix. Their coating with OH- groups derived from phenolic compounds increases their potential in a wide range of applications, from drug delivery and cancer therapies to environmental remediation and the development of advanced sensors. Furthermore, their potential in agriculture to enhance nutrient absorption and as remediation agents underscores their versatility. This sustainable approach not only reduces the use of harmful chemicals, but their characteristics also give nanoparticles advantages and new possibilities in various scientific and technological fields.
