Study of alternative compounds framed in green chemistry as stabilizing agents of metallic nanoparticles

Project Details


The concern for environmental problems has led to a focus on chemistry that aims to prevent or minimize pollution from its origin both on an industrial scale and in research or teaching laboratories. the development of chemical products from renewable resources is framed in the desire and awareness that today's society has taken for the care and conservation of the environment. in the synthesis of metallic nanoparticles, it is necessary to use stabilizing and reducing agents that can become toxic and therefore limit the applications of the synthesized nanoparticles. in this project the synthesis of metal nanoparticles is proposed, using the chemical reduction method but using stabilizers and renewable reducing agents, friendly to the environment and biocompatible that extend the applications of the synthesized nanoparticles


General to establish the stabilizing and / or reducing function of natural extracts in the synthesis of silver nanoparticles, for their potential application in biocompatible compounds. specific • identify possible extracts of plants or fruits of our region with reducing and stabilizing capacity. • synthesize silver nanoparticles using the most convenient extracts in the synthesis processes. • optimization of the synthesis to guarantee adequate shape and size. • characterize the silver nanoparticles, to determine the properties required in the application of interest. • make pilot tests in the laboratory to determine the possible bactericidal activity of the nanoparticles synthesized using natural extracts.

Expected results

The approach of the following methodology will allow the development and execution of the objectives set for this project, considering that such research has in principle a basic character. review and update of the bibliography: due to the latest developments and research dynamics, a constant updating of the information is necessary in different aspects such as: alternatives and modifications of the synthetic routes of the nanoparticles (materials), analysis of precursors of origin natural that improve the stability, biocompatibility of the formed materials that allow the modulation of the size and morphology.interpretation and choice of material characterization techniques using different spectroscopic and spectrometric techniques. uses and application of the materials obtained in the remediation of waters, improvement of mechanical properties of materials (as additives), analysis of the possible antibacterial and / or microbial activity. this search will be carried out using diverse scientific information databases, both nationally and internationally.synthesis of nanoparticles (np-type materials) in the study of nanoparticle-type materials, the use of different synthesis strategies (synthesis by ultrasound, in inert atmosphere, programmed temperature) that allow the modulation of parameters such as size and morphology will be analyzed.ensuring control of the activity of nanoparticles and their possible application in different fields (reinforcing agents, in the remediation of heavy metals). this study will be carried out mainly in the laboratories of the university of medellín using resources such as the high vacuum line, flame emission spectroscopy, lyophilization among others.
