“…Interestingly, ensuring that the Cu, Nd, and Cd are in a 94:3:3 ratio (Cu/Nd/Cd) facilitates the growth of long rod-like structures with sizes ranging between 26.24 and 211.60 nm. The equal molar ratio of Nd and Cd promotes the growth direction of the 2D nanorods over 200 nm [53].…”

“…In in vitro models of human skin epithelial cells and human embryonic kidney cell lines, CuO nanomaterials have been used for biocompatibility assessments. Typically, >90%-80% cell viability is considered non-toxic and acceptable for biological application [53,98,99]. When doped with metal, the CuO sample exhibited higher cytotoxicity than the pristine CuO nanomaterials, a difference attributed to size, shape, stability, and ion-releasing ability variations.…”

“…The pristine CuO nanomaterials demonstrated 80% cell viability at a 150 µg/mL concentration. Except for the Cu:Cd (94:6) sample, all the other samples maintained cell survivability between 90 and 80% at concentrations ranging from 25 to 75 µg/mL [53]. Nonetheless, the excessive production and usage of nanomaterials has made living organisms (humans/animals (higher to lower)/plants/microbes), as well as the environment, vulnerable to toxicity [100].…”

Recently, functional nanomaterials with unique sizes, shapes, and surface chemistry have been fabricated for various applications in all facets of science and technology. Among these diverse nanomaterials, copper oxide nanoparticles (CuO NPs) have garnered considerable attention due to their unique physicochemical parameters and semiconductor properties. Doping various functional materials in CuO NPs and the fabrication of CuO nanofillers functionalized with natural or synthetic moieties delivers improved antibacterial efficacy in food packaging applications. Moreover, the bactericidal effect of modified CuO NPs against foodborne pathogens largely contributes to their usage in food packaging technology. Therefore, it is essential to fabricate effective antimicrobial CuO nanofillers with minimal or no adverse side effects. This review discusses the synthesis, characterization, surface modification, antibacterial properties, food packaging applications, and toxicological implications of the diverse CuO nanofillers integrated in films and composites. In addition, it highlights their adverse side effects and ways to combat adverse situations. The forthcoming generation is expected to lead a groundbreaking surge of inventive food packaging systems (FPS) based on CuO hybrid nanofillers in food packaging industries.

Spectroscopic analysis of trivalent praseodymium (Pr+3) and neodymium (Nd+3) ions have received very much interest and reveals good fluorescence efficiency in visible and near IR (NIR) region. Cadmium sulfide (CdS) nanomaterial sample doped with Pr+3 and Nd+3 ions are synthesized at room temperature by simple chemical precipitation method. The synthesized sample has been characterized by powder X‐ray diffraction studies, scanning electron microscopy, transmission electron microscopy, and energy dispersive X‐ray spectra. Absorption spectra of CdS:Nd3+ and CdS:Pr3+ nanoparticles have been recorded at room temperature. Various parameters such as interplanar spacing, micro strain, dislocation density, distortion parameter, and particle size of nanomaterial are computed. TEM and XRD analysis reveal the spherical structure of the CdS:Nd3+ and CdS:Pr3+ nanoparticles in the prepared samples. Energy interaction parameters of the CdS:Nd3+ and CdS:Pr3+ nanoparticles are computed using UV‐visible absorption spectrum. Actually, CdS nanoparticle amplifies the luminescence intensity of Pr+3, Nd+3 ions by up conversion processes. So energy transfer can be observed from CdS nanoparticles doped with Pr+3, Nd+3 ions. Therefore, the use of pump sources and diode lasers in the UV range can be used to excite these samples to work as lasers. CdS:Nd3+ and CdS:Pr3+ nanoparticles find potential application as a window material for hetero‐junction solar cell, light emitting diodes (LED), biological sensors, address decoders, gas detectors, opto‐electronic devices, etc. CdS nanomaterials are also used as pigment in paints and in engineered plastic due to their good thermal stability.

Green synthesis nanoparticles have gained interest in recent years due to their environmental friendliness and sustainability. The current study focuses on the green synthesis of BMNP using spearmint leaves as a reducing and stabilizing agent. Because of their excellent catalytic characteristics, the synthesized bimetallic nanoparticles function as an effective catalyst in pyrido[2,3‐d:6,5‐d] pyrimidine derivatives. The synthesized nanoparticles are characterized using a variety of techniques, including FT‐IR analysis, SEM & EDX, XRD, and TEM. The FT‐IR study shows a reduction in functional groups in the leaf extract, confirming the metal nanoparticles’ stretching. SEM and EDX studies confirm the shape and elemental composition of bimetallic nanoparticles. XRD investigation showed that the synthesized NPs are crystalline, and the Scherrer equation was used to calculate the average crystallite size. The calculated size was 49 nm. TEM analysis confirms the core‐shell nature of BMNPs. The synthesized nanoparticles acted as a superior catalyst in pyrido[2,3‐d:6,5‐d] dipyrimidines derivatives. in the synthetic procedure, BMNPs enhanced the catalytic activity and reduced the reaction time with more yield, Compared to the previous study. and the synthesized compound [1–5] has been confirmed by FT‐IR, 1H‐NMR, and 13C‐NMR analysis. and it has given better results in in‐vivo anti‐diabetic activity by Streptozotocin nicotinamide. This induced model adult male albino Wistar derivatives show significant fasting blood glucose levels when compared to metformin hydrochloride. and its evaluated molecular docking study, exhibit excellent CDDOCKER energy.
