New application of two Antarctic macroalgae Palmaria decipiens and Desmarestia menziesii in the synthesis of gold and silver nanoparticles

In this study, two Antarctic macroalgae (Rhodophyta Palmaria decipiens and Phaeophyta Desmarestia menziessi) were selected in order to report their use for the biosynthesis of nanomaterials. Two aqueous extracts of the macroalgae were prepared and their reducing activity, total phenolic content and...
