Synthesis of CdSe Nanoparticles and Their Effect on the Antioxidant Activity of Spirulina Platensis and Porphyridium Cruentum Cells

Abstract

Single-crystalline cadmium selenide nanoparticles were obtained using HTSPS synthesis. X-Ray powder diffraction and transmission electron microscopy were used to confirm the crystallinity and morphology of the resulting nanoparticles. To study the action of CdSe on antioxidant activity, we selected two biotechnological important strains of microalgae: cyanobacteria Spirulina platensis and red microalga Porphyridium cruentum. In the case of Porphyridium cruentum, the obtained results demonstrated an increase in the productivity. For Spirulina platensis, the presence of the compound in the cultivating medium decreased the productivity of cyanobacteria.
