QCM-Based MgFeO@CaAlg Nanocomposite as a Fast Response Nanosensor for Real-Time Detection of Methylene Blue Dye.

Methylene blue (MB) dye is a common colorant used in numerous industries, particularly the textile industry. When methylene blue is discharged into water bodies without being properly treated, it may seriously damage aquatic and human life. As a result, a variety of methods have been established to remove dyes from aqueous systems.

Sustainable and Efficacy Approach of Green Synthesized Cobalt Oxide (CoO) Nanoparticles and Evaluation of Their Cytotoxicity Activity on Cancerous Cells.

In this study, rosemary leaf extract was effectively used to synthesize cobalt oxide nanoparticles (CoO NPs) using a rapid, low-cost, and environmentally friendly approach. The prepared CoO NPs were examined using various analytical techniques. However, UV spectrum analysis displayed two sharp absorption peaks at ~350 and 745 nm.

Design of a Novel Nanosensors Based on Green Synthesized CoFeO/Ca-Alginate Nanocomposite-Coated QCM for Rapid Detection of Pb(II) Ions.

Pb(II) is a significant contaminant that is known to have negative effects on both humans and animals. Recent industrial operations have exacerbated these consequences, and their release of several contaminants, including lead ions, has drawn attention to the potential effects on human health. Therefore, there is a lot of interest in the rapid, accurate, and selective detection of lead ions in various environmental samples.

Evaluation of Green-Synthesized Cuprospinel Nanoparticles as a Nanosensor for Detection of Low-Concentration Cd(II) Ion in the Aqueous Solutions by the Quartz Crystal Microbalance Method.

Cd(II) heavy metal is an extremely dangerous hazardous material for both humans and the environment. Its high toxicity is the reason behind the examination of new techniques for detecting very small concentrations of Cd(II). Recently, Quartz Crystal Microbalance (QCM) has been one of the techniques that have been widely used to detect trace heavy metal ions in solutions.

Efficient Green Synthesis of (FeO) and (NiFeO) Nanoparticles Using Star Anise () Extract and Their Biomedical Activity against Some Cancer Cells.

Magnetite FeO and spinel (2:1) and (4:1) NiFeO magnetic nanoparticles (MNPs) were prepared by simple and affordable co-precipitation methods using an extract of star anise () as a green reducing agent. The morphology and chemical composition of these MNPs were confirmed by field-emission scanning electron microscopy, energy-dispersive X-ray spectroscopy, UV-visible spectroscopy, and X-ray diffraction (XRD). The synthesized magnetite FeO and spinel (2:1) and (4:1) NiFeO MNPs were in the size range of 0.

Antimicrobial Activity of Ca-Alginate/Chitosan Nanocomposite Loaded with Camptothecin.

The main aim of this study was to prepare antimicrobial nanocomposites consisting of alginate, chitosan, and camptothecin (CPT). CPT-loaded calcium alginate (Ca-Alg) and calcium alginate/chitosan (Ca-Alg-CH) nanomaterials were synthesized and characterized using infrared (IR) spectroscopy, X-ray diffraction (XRD), UV-Vis spectroscopy, and scanning electron microscopy (SEM). The antimicrobial activity and the genetic effects of Ca-Alg/CPT and Ca-Alg-CH/CPT nanomaterials on , , and were studied.
