“…Agarose could be extracted from red seaweeds with 1 20 000 Da molecular weight . Recently, Kargar et al used agarose as an ecofriendly, natural, cost‐effective, capping agent, and stabilizer for cerium oxide NPs synthesis and showed that the presence of agarose can play a positive role in the synthesis process . To the authors' knowledge, no works have been devoted to the effect of agarose addition on the phase and morphology evaluation of CoFe 2 O 4 NPs by sol‐gel.…”

Hard‐magnetic CoFe2O4 nanoparticles were produced with the sol‐gel autocombustion route using agarose and citric acid as a neutral organic gel and combustion agent. For this purpose, the obtained gel is annealed at 800°C for 3 hours and then the spinel structure of the samples was confirmed by X‐ray diffraction (XRD). In addition, the existence of metal‐oxygen complexes in the gel and nanoparticles was investigated by Fourier transformation infrared (FTIR) spectra. Furthermore, FESEM images showed that semispherical and rod‐like particles were obtained by variation in agarose contents. For the rod‐like sample with 2.5 g agarose, the saturation magnetization and coercivity were measured equal to 71.7 emu/g and 10076.84 Oe, respectively.

“…50 Kargar et al reported the green synthesis of small cerium oxide NPs, stabilized with agarose polymers via a sol-gel method. 51 While heating to 90°C, the agarose powder is normally dissolved in water, and when the temperature is reduced to 35°C-40°C, semisolid gel is formed that is stable over a wide pH range of (from 3 to 9). Interpenetrating H-binding between sugar moieties resulted in production of this sol-gel network and nanochannel containing pore sizes of 200 nm.…”

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.

Qidwai, et al.: Biogenic Advances in NanoparticlesInnovations in the nanotechnological arena have paved a path leading to nano-revolution, which has most recently unfurled the role of plants in the biogenic synthesis of nanoparticles. Though synthesis of nanoparticles can be accomplished through physical and chemical techniques, biological course of synthesis has proficiently proved competent over other techniques. The problem of evolving multidrug resistant bacteria, due to irrational use of antibiotics, makes the biogenically synthesized nanoparticles attractive, due to their promising efficacy with negligible side effects. Consequently, the nanoparticles becoming better substitutes for conventional treatment besides overcoming all the limitations. Nanoparticles have great stability and potent antibacterial activity. The uniqueness lies in their size (10 and 500 nm) and dimension offers these particles to dynamically communicate with biomolecules on the cell surfaces and within the cells, so proficiently to decode and designate various biochemical and physiochemical properties of the cells. The present review aims to recapitulate various emerging efforts in the biogenic synthesis of nanoparticles, most significantly their unique mechanisms of action with different approaches as well as the factors that may add up to their antimicrobial activity.
