Production of Cobalt Ferrite Nanoparticles via Green Synthesis using Aloe Vera

In view of the increasing prominence of environmental issues on the global agenda, the pursuit of sustainable practices has intensified. In the midst of this, green chemistry has emerged as a relevant approach to address the challenges of chemical pollution and promote sustainable practices in industry and research, paving the way for the development of more efficient and eco-friendly technologies in the field of nanomedicine. The present study aimed to explore the fundamentals of green chemistry in the synthesis of cobalt ferrite nanoparticles, which have been studied for various applications, such as medicine. In addition to cobalt nitrate and iron nitrate, we used Aloe vera mucilage to synthesize cobalt ferrite nanoparticles. The choice of Aloe vera was based on its rich composition of polysaccharides and phytochemicals, which offers stabilizing properties for nanoparticles. The synthesis was performed in a microwave reactor. Analysis of zeta potential and particle size by dynamic light scattering (DLS) revealed variations in sample stability and yielded particle sizes. Scanning electron microscopy (SEM) confirmed the formation of nanoparticles, although differences in morphology and agglomeration were observed among the samples. The results demonstrate that the adopted green synthesis approach shows promising potential for the production of nanoparticles with possible therapeutic applications.
