“…Therefore, the microenvironment and synthesis method adopted also plays an important role in determining the biological activity and toxicity of solvothermal, 21 ball milling, 22 thermal decomposition, 23 spray pyrolysis, 24 thermal hydrolysis 25 and sol-gel methods. [26][27][28] However, applying the mentioned methods deals with several drawbacks, such as toxic solvents and reagents usage, high temperature and pressure, and the requirement of external additives as stabilizing or capping agents during the reaction. As the physiochemical properties of NPs mostly depend on the synthesis procedure, the synthesis method of NPs for biological applications is very important.…”

CeO 2 nanoparticles (NPs) have shown promising approaches as therapeutic agents in biology and medical sciences. The physicochemical properties of CeO 2 -NPs, such as size, agglomeration status in liquid, and surface charge, play important roles in the ultimate interactions of the NP with target cells. Recently, CeO 2 -NPs have been synthesized through several bio-directed methods applying natural and organic matrices as stabilizing agents in order to prepare biocompatible CeO 2 -NPs, thereby solving the challenges regarding safety, and providing the appropriate situation for their effective use in biomedicine. This review discusses the different green strategies for CeO 2 -NPs synthesis, their advantages and challenges that are to be overcome. In addition, this review focuses on recent progress in the potential application of CeO 2 -NPs in biological and medical fields. Exploiting biocompatible CeO 2 -NPs may improve outcomes profoundly with the promise of effective neurodegenerative therapy and multiple applications in nanobiotechnology.

Featured Application: Greener synthesis and applications of Core-shell nanoparticles.Abstract: Among an array of hybrid nanoparticles, core-shell nanoparticles comprise of two or more materials, such as metals and biomolecules, wherein one of them forms the core at the center, while the other material/materials that were located around the central core develops a shell. Core-shell nanostructures are useful entities with high thermal and chemical stability, lower toxicity, greater solubility, and higher permeability to specific target cells. Plant or natural products-mediated synthesis of nanostructures refers to the use of plants or its extracts for the synthesis of nanostructures, an emerging field of sustainable nanotechnology. Various physiochemical and greener methods have been advanced for the synthesis of nanostructures, in contrast to conventional approaches that require the use of synthetic compounds for the assembly of nanostructures. Although several biological resources have been exploited for the synthesis of core-shell nanoparticles, but plant-based materials appear to be the ideal candidates for large-scale green synthesis of core-shell nanoparticles. This review summarizes the known strategies for the greener production of core-shell nanoparticles using plants extract or their derivatives and highlights their salient attributes, such as low costs, the lack of dependence on the use of any toxic materials, and the environmental friendliness for the sustainable assembly of stabile nanostructures.
