Green synthesis of silver nanoparticles (AgNPs) using Nannochloropsis oculata biomass
Keywords:
Nanotechnology, Metallic Nanoparticles, Biosynthesis, MicroalgaeAbstract
Silver Nanoparticles (AgNPs) are widely studied in nanotechnology due to their numerous applications in various fields. However, traditional synthesis methods for AgNPs have significant environmental disadvantages. In order to address this issue, green synthesis methods have been explored as more efficient, cost-effective, and environmentally friendly alternatives. Microalgae have emerged as promising agents for silver ion reduction in green synthesis, with Nannochloropsis oculata being particularly effective. While previous studies have focused on the use of whole microalgae, the potential of deoiled microalgal biomass, a by product of biofuel production, remains unexplored. This project aims to investigate the synthesis of AgNPs using complete and deoiled biomass of N. oculata, comparing two heating methods: microwave-assisted heating and agitation. The study's objectives include determining the most effective combination for AgNPs synthesis and assessing their potential applications. The results obtained revealed that all the analyzed conditions led to the formation of nanoparticles of various shapes and sizes, as evidenced through UV-vis spectroscopy. The findings of this study could contribute to the sustainable acquisition of nanotechnology resources, the reduction of waste in the synthesis of AgNPs, and the development of nanomaterials with potential antimicrobial and antioxidant properties.
