“…In the last few years, the field of non-thermal plasma has expanded significantly. The topic of chemical interactions between non-thermal plasma and liquids attracted the attention of researchers due to its potential medical and economic benefits (Rumbach et al 2013 ; Mohammed et al 2022a , b ). Recently, nanomaterial (NM) synthesis through plasma–liquid interactions (PLIs) is a new branch of plasma research that has grown rapidly.…”

Advancements in nanomedicine helped scientists design a new class of nanoparticles known as hybrid nanoparticles (core/shell) for diagnostic and therapeutic purposes. An essential requirement for the successful use of nanoparticles in biomedical applications is their low toxicity. Therefore, toxicological profiling is necessary to understand the mechanism of nanoparticles. The current study aimed to assess the toxicological potential of CuO/ZnO core/shell nanoparticles with a size of 32 nm in Albino female rats. In vivo toxicity was evaluated by oral administration of 0, 5, 10, 20, and 40 (mg/L) of CuO/ZnO core/shell nanoparticles to a female rate for 30 consecutive days. During the time of treatment, no deaths were observed. The toxicological evaluation revealed significant (p < 0.01) alteration in white blood cells (WBC) at a 5 (mg/L) dose. Also, increase in red blood cells (RBC) at 5, 10 (mg/L) doses, while hemoglobin (Hb) levels and hematocrit (HCT) increased at all doses. This maybe indicates that the CuO/ZnO core/shell nanoparticles stimulated the rate of blood corpuscle generation. The anaemia diagnostic indices (mean corpuscular volume MCV and mean corpuscular haemoglobin MCH) remained unchanged throughout the experiment for all the doses tested 5, 10, 20, and 40 (mg/L). According to the results of this study, exposure to CuO/ZnO core/shell NPs deteriorates the Triiodothyronine hormone (T3) and a Thyroxine hormone (T4) activated by Thyroid‐Stimulating Hormone (TSH), which is generated and secreted from the pituitary gland. There is possibly related to an increase in free radicals and a decrease in antioxidant activity. Significant (p < 0.01) growth retardation in all groups treated due to rats’ infection by Hyperthyroidism induced by thyroxine (T4) level increase. Hyperthyroidism is a catabolic state related to increased energy consumption, protein turnover, and lipolysis. Usually, these metabolic effects result in weight reduction and a decrease in fat storage and lean body mass. The histological examination indicates that the low concentrations of CuO/ZnO core/shell nanoparticles are safe for desired biomedical applications.

“…In recent years, a new type of hybrid NPs called "core–shell NPs" has been developed, consisting of two or more types of single nanomaterials 8 . Researchers have found that the majority of NPs' physical characteristics are dependent on their nanostructured surfaces due to the characteristics of NPs that help increase the number of dangling bonds that affect their physicochemical properties.…”

Given their versatile nature and wide range of possible applications, core–shell nanoparticles (NPs) have received considerable attention. This paper proposes a novel method for synthesizing ZnO@NiO core–shell nanoparticles using a hybrid technique. The characterization demonstrates the successful formation of ZnO@NiO core–shell nanoparticles, which have an average crystal size of 13.059 nm. The results indicate that the prepared NPs have excellent antibacterial activity against both Gram-negative and Gram-positive bacteria. This behavior is primarily caused by the accumulation of ZnO@NiO NPs on the bacteria's surface, which results in cytotoxic bacteria and a relatively increased ZnO, resulting in cell death. Moreover, the use of a ZnO@NiO core–shell material will prevent the bacteria from nourishing themselves in the culture medium, among many other reasons. Finally, the PLAL is an easily scalable, cost-effective, and environmentally friendly method for the synthesis of NPs, and the prepared core–shell NPs could be used in other biological applications such as drug delivery, cancer treatment, and further biomedical functionalization.

“…Metal nanoparticles that appear in size ranging from 1 -100 nm have received increasing interest due to their optical and optoelectronic properties that are unique compared to their bulk counterparts; this has made them enter into different fields such as catalysis, optics, environmental, electronics, and biotechnology, which is an area of constant interest (1,2). Among these, silver nanoparticles (AgNPs) are widely used in a variety of applications because they have a small size, large surface area, and high dispersive capacity and exhibit anti-microbial, anticancer, anti-diabetic, anti-oxidant, anti-inflammatory properties and also used in food preservation, water purifications ointment fabrication, and cosmetics (3,4).…”

To create silver nanoparticles, researchers use bionanotechnology techniques because they are economical and environmentally friendly. The current study shows that lemon juice (Citrus-limon) can be used to biosynthesize silver nanoparticles (Ag NPs). The synthesized silver nanoparticles have been characterized by the surface plasmon resonance (SPR) measured at λmax = 430 nm, confirming the formation of AgNPs. Moreover, Fourier Transform Infrared (FTIR) analysis was carried out to identify possible bio-molecules responsible for the bio-reduction of silver ions. The x-ray diffraction (XRD) peaks at (111, 200, 220, 222, and 311) confirm the found face-centered cubic (FCC) crystal structure of AgNPs in solution. Transmission-Electron-Microscopy (TEM) images showed that AgNPs have spherical morphology with sizes ranging from 10-50 nm. Furthermore, the Particles Size Analyzer (PSA) confirmed these sizes and ranges. Synthesized AgNPs have high anti-oxidant activity according to the (scavenging of DPPH radicals, total anti-oxidant, and reducing power) assays. Also, the anti-bacterial activity of AgNPs was evaluated by a well diffusion method, and the results suggest that they are more sensitive to gram-positive bacteria than gram-negative ones, with the average diameter of the inhibition zones for AgNPs ranging from 4.11 to 25.87 mm and 1.38 to 22.3 mm against S. aureus and E. coli bacteria, respectively. In vitro studies of AgNPs against MCF-7 breast cancer cell s lines showed a good cytotoxic effect p<0.05 with an IC50 value of 47 μg/mL; this study could be beneficial for nanotechnology-based pharmaceutical and biomedical applications.
