“…Appu et al (2021) reported that the UV spectral analysis of chitosan (Cs)-coated iron oxide (Fe3O4) nanocomposites (NCs) by employing the aqueous leaf extract of Brassica oleracea L. showed peak at 290 nm due to strong surface plasmon resonance (SPR). Similarly, Boudouh et al (2021) documented the exhibition of black color during the fabrication of FeO NPs. The Cs-FeNPs has displayed a maximum absorbance peak at 233 nm and thus indicated a convenient surface plasmon resonance character for FeO nanoparticles.…”

The present investigation was aimed to develop an easy, low-cost and eco-friendly method for the synthesis of Chitosan based iron oxide Nanoparticles (Cs-FeNPs) using shells of Penaeus monodon. The synthesized Cs-FeNPs were characterized by using Ultraviolet-Visible spectroscopy (UV), Fourier-Transform Infrared spectroscopy (FT-IR), X-ray Diffraction (XRD), Transmission Electron Microscope (HR-TEM) and Scanning Electron Microscope (SEM with EDAX). The visible dark black color formation and surface plasmon resonance at 233 nm indicates the biosynthesis of Cs-FeNPs. The TEM images showed polydispersal, and spherical Cs-FeNPs particle size of 3 to 5 nm. Antibacterial activity of chitosan aqueous extract and Cs-FeNPs showed an excellent activity against Gram-positive bacteria (Staphylococcus aureus and Enterococcus faecalis) and Gram-negative bacteria (Escherichia coli, Enterobacter, Klebsiella pneumoniae and Pseudomonas aeruginosa).

“…Biogenic conversion of iron (II) sulfate to CS/FeO NC was initiated by mixing of FeSO4 and CS with S. acuta aqueous leaf extract, which also stimulated the color change from yellowish to black, and thus supported the development of CS/FeO NC (Figure2(Aa)). Similarly, Boudouh et al (2021)[34] documented the exhibition of black color during the fabrication of FeO NPs. Secondary metabolites present in S. acuta leaf extract and free amino, and hydroxyl groups existing in CS might have joined with ferrous ions (Fe II ) and formed Fe-ellagate conjugate.…”

Chitosan (CS) functionalization over nanomaterials has gained more attention in the biomedical field due to their biocompatibility, biodegradability, and enhanced properties. In the present study, CS functionalized iron (II) oxide nanocomposite (CS/FeO NC) was prepared using Sida acuta leaf extract by a facile and eco-friendly green chemistry route. Phyto-compounds of S. acuta leaf were used as a reductant to prepare CS/FeO NC. The existence of CS and FeO crystalline peaks in CS/FeO NC was confirmed by XRD. FE-SEM analysis revealed that the prepared CS/FeO NC were spherical with a 10–100 nm average size. FTIR analyzed the existence of CS and metal-oxygen bands in the prepared NC. The CS/FeO NC showed the potential bactericidal activity against E. coli, B. subtilis, and S. aureus pathogens. Further, CS/FeO NC also exhibited the dose-dependent anti-proliferative property against human lung cancer cells (A549). Thus, the obtained outcomes revealed that the prepared CS/FeO NC could be a promising candidate in the biomedical sector to inhibit the growth of bacterial pathogens and lung cancer cells.

“…Numerous studies have claimed the addition of nanoparticles which improved drilling fluids by providing optimal rheological and filtration properties, increased shale stability, and enhanced wellbore strengthening as alternatives to costly chemicals [13,17,22]. The petroleum industry has been looking for polymers or natural products that are multifunctional, biodegradable, thermally stable, and environmentally friendly in order to build smart drilling fluids for petroleum exploration and extraction [23].…”

“…It is noteworthy that olive leaves contain a variety of potentially bioactive chemicals, including hydroxytyrosol and oleuropein fragments, which may have antioxidant properties [22,31]. Based on earlier studies, it is not clear how the concentration of Fe 3 O 4 -NPs additives could affect the overall performance of the rheological and filtration properties.…”

Recently, value-added nanomaterials including nanoparticles or nanofluids have been significantly used in designing drilling fluids with tunable rheological properties to meet specific downhole and environmental requirements. In this work, we report novel water-based drilling fluids (WBDF) containing eco-friendly Fe3O4 nanoparticles (Fe3O4-NPs) prepared by using olive leaves extract (OLE) as a reducing and capping agent. A series of economical and excellent performance of WBDF was obtained by introducing low, medium, and high concentrations of Fe3O4-NPs into the conventional WBDF. The synthesis of Fe3O4-NPs was accomplished through the thermal decomposition of iron precursors in an organic medium. NPs were added to the based fluid at concentrations of 0.01, 0.1, and 0.5 wt%. Emission scanning microscopy (FESEM), field- and Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Energy-dispersive X-ray analysis (EDX) were used for Fe3O4-NPs analysis. Compared to the conventional WBDF, the addition of Fe3O4-NPs as an additive in the based fluids has been investigated to help increasing viscosity and yield point, which is advantageous for hole cleaning, as well as decreasing fluid loss and mud cake thickness.
