Key concepts
Scholarcy highlights
- The unquenchable interest in nanomaterials and nanosystems is due to their unique properties and the possibility of targeted synthesis of such materials, in particular nanoparticles with required size and predicted properties
- For the solutions prepared with ethylenediaminetetraacetic acid, the particle size was large, but the band was much narrower, which indicates a smaller distribution of nanoparticles by radius
- The antibacterial activity was studied using the example of a system containing spherical nanoparticles of AgEDTA, which was determined from the size of the formed inhibition zone concerning two types of pathogenic bacteria: Bacillus subtilis and Escherichia coli
- AgEDTA complexonate, a nanodisperse system based on it, and a nanosilver solution have been obtained by the reduction of Argentum nitrate with a Na2EDTA solution were obtained
- The particle size of the precipitated complexonate powder was in the range of 20–70 nm depending on the solvent used in the precipitation process
- Metal nanoparticles are stabilized by the complex ion AgEDTA3in the case of complexonate, and in the case of colloidal solutions, the stabilizer is a solution of Na2edta
- The larger particle size of the powder compared to solutions is due to its conglomeration
