“…In recent years, the rapid advancement of nanotechnology has led to the widespread utilization of engineered nanostructured metal oxides (ENMOs) in various industrial and biomedical applications [ 1 ]. Nanoparticles (NPs) are described by the International Organization for Standardization as structures characterized by one, two, or three dimensions within the range of 1 to 100 nm [ 2 ]. The diminutive size of nanoparticles contributes to a significantly high surface area with respect to volume, resulting in enhanced reactivity, improved stability, and augmented functionality.…”

Nanoparticles (NPs) are considered as versatile tools in various fields including medicine, electronics, and environmental science. Understanding the structural aspects of surface modifiers in nanoparticles that govern their cellular uptake is crucial for optimizing their efficacy and minimizing potential cytotoxicity. The cellular uptake is influenced by multiple factors, namely, size, shape, and surface charge of NPs, as well as their surface functionalization. In the current study, classification-based ML models (i.e., Bayesian classification, random forest, support vector classifier, and linear discriminant analysis) have been developed to identify the features/fingerprints that significantly contribute to the cellular uptake of ENMOs in multiple cell types, including pancreatic cancer cells (PaCa2), human endothelial cells (HUVEC), and human macrophage cells (U937). The best models have been identified for each cell type and analyzed to detect the structural fingerprints/features governing the cellular uptake of ENMOs. The study will direct scientists in the design of ENMOs of higher cellular uptake efficiency for better therapeutic response.

“…Metal oxide nanoparticles are one of the most prepared and used classes of metal-based nanoparticles due to their ease of preparation (which could be achieved by simply using plant extracts) and their outstanding properties [8]. They possess distinctive characteristics with far-reaching implications in the fields of science and technology including a high surface-to-volume ratio, extensive surface area, and widespread availability on Earth [9]. Other unique properties which made them applicable to a field like biomedical sciences include, the ease of incorporation into hydrophilic and hydrophobic systems and functionalization by various molecules due to their negatively charged surfaces [10].…”

Nickel oxide (NiO) nanoparticles are gaining popularity in multiple fields owing to their useful properties. The application in biomedicine has been further enhanced by combining them with plant extracts that possess unique biological properties. In this report, NiO nanoparticles was synthesized by mediating the reaction process with the leaf extracts of Kei-apple (Dovyallis Caffra), a local fruit tree found in South Africa. The properties of the prepared NiO material was then established using the characterization techniques such as X-ray diffraction (XRD), UV–Vis spectroscopy (UV–Vis), transmission electron microscope (TEM), Scanning electron microscope (SEM), and Energy dispersive X-ray analysis (EDX). The XRD report obtained confirmed the formation of a crystalline NiO nanoparticles, while the microscopic techniques showed that the material possessed a spherical shaped which tends towards polyhedron structure, with an average diameter size of 11.38 nm. The purity of the material was shown in the EDX analysis in which the primary composition was only the elemental constituents of the NiO nanoparticles. The nanoparticles exhibited a good cytotoxicity comparable to the 5-Fluorouracil in both the human cervical cancer (HeLa) and Human embryo kidney (HEK 293) cell lines, with a minimum inhibitory concentration (IC50) of 0.00015and 13.8 µg/mL, respectively. The anti-inflammatory study on the other hand exhibited a weak anti-inflammatory effect in the used Bovine serum albumin denaturation assay. The finding here thus suggests that the Kei-apple mediated NiO nanoparticles can be safely used in different field without causing harm to the human body due to the specificity to the cancerous cell line and the observed weak viability in the used non-cancerous embryonic kidney cells.

“…Refer to the nanoparticles' size and altering their surface characteristics to manipulate special optical, interfacial, magnetic, chemical or electrical features for making them more promising for operational utilizations, NPs flooding may alter the interfacial tension (IFT) and surface wettability through the porous media [3]. Aluminum oxide, magnesium oxide, zirconium dioxide, cerium(IV) oxide, titanium dioxide, zinc oxide and iron(III) oxide have the most widely utilized, exhibiting the excellent chemical and physical characteristics in various applications [4]. Some recent works on the nanostructure-assisted chemical oil recovery processes were tabulated in Table 1.…”

One of the most important aspects to use the nanofluid flow through the oil recovery process is physical and chemical constraints at high salinity and temperature, harsh conditions, leading to the instability and further problems. In this study, the stability of various nanoparticles, Al2O3, SiO2, ZrO2, TiO2, Fe2O3, nanoclay, and ZnO, were examined upon the concentration (0.01 to 3 wt%), temperature (ambient and 75℃), salinity (20,000 to 80,000 ppm), pH (2 to 12), and stabilizers of polyethylene glycol, polyvinylpyrrolidone, guar gum, Triton X-100, sodium dodecyl sulfate, cetrimonium bromide. Then, the most stable nanofluid was nominated to investigate the oil recovery mechanisms by performing interfacial tension (IFT), wettability alteration, and micromodel flooding analyses. Zinc oxide and silicon dioxide nanofluids were maintained their stability at the harsh conditions and guar gum showed a good performance in stabilizing nanofluids, compared to other nanofluids agglomerated. According to the results of the IFT reduction upon the nanofluid and reservoir crude oil (1.64 mN/m), wettability alteration of carbonate cores (113.68 degree) and micromodel experiments (additional recovery of 32.23% and 6.27% in the secondary and tertiary flooding, respectively) all compared to the seawater, the ZnO nanofluid stabilized by guar gum was an excellent candidate to use in the oil recovery projects.
