Advances in the Optimization of Fe Nanoparticles: Unlocking Antifungal Properties for Biomedical Applications

“…The main benefit of this approach is its ability to produce a large number of particles with various size distributions. However, it has some drawbacks, such as difficulty in obtaining homogenous and monodisperse NPs and wastewater with a high pH, which may be harmful to the environment [30]. Al-Alawy et al (2018) successfully manufactured Fe NPs using a co-precipitation method involving a combination of Fe +2 and Fe +3 ions in an alkaline solution.…”

“…The initial substance used in the experiment was ferric nitrate, which was mixed with ethylene glycol under continuous agitation, leading to the formation of a brown gel. The gel was allowed to stand for a duration of 2 h and subsequently subjected to a heating process at a temperature of 80 °C for approximately 4 h. Following the completion of the drying process, the gel was annealed in a temperature range of 200-400 °C in a vacuum environment [30] Batool et al (2023) employed the sol-gel technique to synthesize FeO NPs at pH levels ranging from 1 to 9. The process of magnetic field annealing (MFA) was conducted on NPs at two distinct temperatures, specifically 200 and 300 °C.…”

“…Understanding the synthetic methodologies and structural properties of Fe NPs is essential for harnessing their full potential [8]. These insights are pivotal for tailoring Fe NPs to specific applications and optimizing their performance in diverse contexts [30]. Silica-coated iron oxide nanoparticles (SiO Fe NPs) have garnered significant interest in the biomedical field, particularly in diagnosis and therapy, owing to their distinctive characteristics including superparamagnetism, facile surface functionalization, and colloidal stability [88].…”

Adsorption‐Based Approaches for Exploring Nanoparticle Effectiveness in Wastewater Treatment

“…Titanium dioxide‐based nanoparticles (TiO 2 NPs): Because of their potent photocatalytic activity, titanium dioxide nanoparticles have demonstrated significant efficacy. This attribute renders them well‐suited for the decomposition of organic contaminants and the removal of heavy metals [86] . Yan et al ., supported by these nanoparticles, achieved an impressive 90 % elimination of lead and cadmium from contaminated water sources.…”

The mechanism of water pollutant photodegradation by mixed and core–shell WO3/TiO2nanocomposites

“…Recently, various techniques, including using a green biochar/iron oxide composite, 7 coated membranes, 8 surfactant-modified biomass, 9 coagulation, 10 modified magnetic nanosorbents, 11,12 hydrochar adsorption, 13,14 and photocatalytic degradation, 15,16 have been applied to remove both cationic and anionic dyes from water. Among these methods, semiconductor-based photocatalysis is thought to be the most promising method because it can convert a broad range of organic contaminants into less toxic compounds, including CO 2 , and H 2 O, without the use of expensive oxidants.…”
