| abstract |
The present invention relates to a composition of nanoparticles of noble metal, in particular gold and silver, associated on biomass components of a brown race with a Chrysophyceae class (so-called anionic composition) and a magnetically modified bionanocomposite. It further relates to a process for the production (biosynthesis) of such bionanocomposites and their use as a catalyst and antibacterial agent. |
