“…2. As seen in the FTIR spectra of all three samples, the absorption peaks around 580 cm − 1 can be attributed to the Fe-O bond [21,22]. In addition, two prominent characteristic peaks around 1632 cm − 1 and 3400 cm − 1 were related to bending vibrations and stretching of the OH group, respectively [23,24].…”

Fe 3 O 4 magnetic nanoparticles (MNPs) have received a great deal of attention in biomedical applications due to their high magnetic sensitivity, large surface area, and superparamagnetic behavior. Their low stability, toxicity, and severe accumulation tendency in aqueous media have, however, hindered their application in hyperthermia treatments. This problem can be resolved by the incorporation of nonmagnetic and biocompatible shells on Fe 3 O 4 . The aim of this research is thus the introduction of Glycerin and Aluminum oxide (Al 2 O 3 ) as two proper materials for coating Fe 3 O 4 and the investigation of their e ciency in this eld. The results indicated that Glycerin@Fe 3 O 4 and Al 2 O 3 @Fe 3 O 4 have a core@shell structure and superparamagnetic features with relatively high saturation magnetization (M S ). The cytotoxicity of the synthesized nanoparticles was evaluated on normal broblast and lung cancer cell lines (A54912) for 24 and 48 hours using the MTT assay. The viability of the A54912 and broblast cell lines in the presence of Fe 3 O 4 was signi cantly lower than the two coated nanoparticles. This implies that the Glycerin and Al 2 O 3 provided the Fe 3 O 4 nanoparticles with proper biocompatibility. The effectiveness of the synthesized NPs in magnetic hyperthermia was evaluated by exposure of the nanoparticle solutions in water (0.2 and 0.4 mg/ml) to a high-frequency alternating magnetic eld for 30 min. the results indicated the achievement of treatment temperature (42-46 ℃) in a short time and elimination of a large percentage of the A54912 cells. In this regard, the present research reported the promising e cacy and e ciency of Glycerin@Fe 3 O 4 and Al 2 O 3 @Fe 3 O 4 in hyperthermia-based cancer treatment.

“…Moreover, the biocatalytic system constructed was used in the degradation of persistent organic pollutants (e.g., bisphenol) in a water environment. Significant investigations involving the biodegradation of phenol were reported by Zhang et al [24] and Li et al [91]. They used Fe 3 O 4 -based composites with carbon nanotubes and nanodiamond, respectively, upon which horseradish peroxidase was immobilized.…”

Purpose of Review Untreated wastewater discharge can significantly and negatively impact the state of the environment. Rapid industrialization and economic development have directly contributed to land and water pollution resulting from the application of many chemicals such as organic dyes, pharmaceuticals, and industrial reagents. The removal of these chemicals before effluent discharge is crucial for environmental protection. This review aims to explore the importance of functionalized materials in the preparation of biocatalytic systems and consider their application in eliminating water pollutants. Recent Findings Wastewater treatment methods can be classified into three groups: (i) chemical (e.g., chemical oxidation and ozonation), (ii) physical (e.g., membrane separation and ion exchange), and (iii) biological processes. Biological treatment is the most widely used method due to its cost-effectiveness and eco-friendliness. In particular, the use of immobilized enzymes has recently become more attractive as a result of scientific progress in advanced material synthesis. The selection of an appropriate support plays an important role in the preparation of such biologically active systems. Recent studies have demonstrated the use of various materials for enzyme immobilization in the purification of water. Summary This review identifies and discusses different biocatalytic systems used in the enzymatic degradation of various water pollutants. Materials functionalized by specific groups can serve as good support matrices for enzyme immobilization, providing chemical and thermal stability to support catalytic reactions. Enzymatic biocatalysis converts the pollutants into simpler products, which are usually less toxic than their parents. Due to immobilization, the enzyme can be used over multiple cycles to reduce the cost of wastewater treatment. Future studies in this field should focus on developing new platforms for enzyme immobilization in order to improve degradation efficiency.
