The green synthesis of silver (Ag) and zinc oxide (ZnO) nanoparticles (NPs), as well Ag/Ag2O/ZnO nanocomposites (NCs), using polar apolar extracts Chlorella vulgaris, offers a sustainable method for producing nanomaterials with tunable properties. impact the environment nanomaterials’ characteristics on cytotoxicity was evaluated by examining reactive species production their effects mitochondrial bioenergetic functions. Cytotoxicity assays PC12 cells, cell line originated from rat pheochromocytoma, an adrenal medulla tumor, demonstrated that Ag/Ag2O NPs synthesized (Ag/Ag2O A) P) exhibited significant cytotoxic effects, primarily driven Ag+ ion release disruption function. However, it is more likely organic content, rather than size, influenced anticancer activity, commercial Ag NPs, despite smaller crystallite sizes, exhibit less effective activity. ZnO P showed increased oxygen (ROS) generation, correlated higher cytotoxicity, while A produced lower ROS levels, resulting in diminished effects. comparative analysis revealed differences LD50 values toxicity profiles. Differentiated cells resistance to ZnO, AgNPs Ag/Ag2O-based materials had similar both types. This study emphasizes crucial role bioactive compounds C. vulgaris modulating nanoparticle surface chemistry, cytotoxicity. results provide valuable insights designing safer biomedical applications, especially targeting tumor-like exploring relationships between polarity, capping agents, nanocomposite structures.

In our research described herein, the hot pressing treatment at 90 °C under 2 tons of pressure on solution cast polymer nanocomposite (PNC) films based a host matrix poly(vinylidene fluoride-co-hexafluoropropylene) (P(VDF-HFP)) and poly(ethylene oxide) (PEO) with varying blend compositions (20, 50, 80 wt% P(VDF-HFP) or PEO) zinc oxide (ZnO) nanofiller, was performed; effects this composition variations optical, thermal, dielectric properties explored. The ultraviolet-visible wavelength range study revealed slightly reduced absorbance little increased energy band gap after films. Differential scanning calorimetry cast-hot pressed (SC-HP) PNC explained thermal stability crystallites also degree crystallinity. broadband measurements these materials, 27 °C, confirmed significant changes in various polarization processes, demonstrating large redistribution constituent interfaces by press treatment. Additionally, film equal compositional ratio further 130 160 step step, characterized to examine properties. thermally treated composite are discussed concerning their use for flexible device applications.

An analysis was conducted on the optical, structural, and dielectric characteristics of PVA/CMC/(1−x)ZnWO 4/x PbS blends. The structures filler samples, undoped, doped blends were examined using X-ray diffraction. crystallite sizes various phases in samples are affected by amount nanocomposite. morphologies different explored scanning electron microscopy. blend exhibited superior absorption Ultraviolet A (UVA) B (UVB) types addition to visible spectrum. optical band gaps minimized (5.37, 5.56, 4.11) (4.76, 3.14, 2.92) eV for direct indirect transitions, respectively, when PVP/CMC with nanocomposite had 10% PbS. highest refractive index, constant,and nonlinear parameter values achieved loaded ZnWO4 only while conductivity obtained as contained 15% fluorescence intensity observed fillers did not contain PbS, it decreased concentration increased.
