In this study, a novel drug delivery system based on zinc oxide nanoparticles (ZnO NPs) was developed for the enhanced delivery of cisplatin (CPT) to improve cancer treatment. The ZnO NPs were synthesized from guava leaf extract and then surface-functionalized with gallic acid (GA) to improve their biocompatibility and drug loading capacity. Pluronic F127, a biocompatible polymer, was then conjugated to the GA-modified ZnO NPs to further enhance their stability and cellular uptake. The resulting NPs were characterized by various techniques, including FT-IR, UV-Vis, SEM, TEM, H NMR, and DLS. The drug loading and release profiles of CPT from the NPs were investigated, showing high CPT loading capacity and pH-dependent release behavior. The cytotoxicity of the NPs was evaluated against various cancer cell lines, demonstrating enhanced cytotoxicity compared to free CPT. Overall, this study highlights the potential of GA and Pluronic-modified ZnO NPs as a promising drug delivery system for enhanced CPT delivery and improved cancer therapy.

The aim of the present work is to investigate the photocatalytic degradation of propyl paraben (propyl para-hydroxybenzoate, PrP) using CuO-ZnO-NPs photocatalyst followed by the identification of the oxidation by-products. The CuO-ZnO-NPs material, synthesized using a green chemistry approach, was used as a photocatalyst for the removal of PrP. The nanoparticles were characterized by XRD, XRF, diffuse reflectance spectroscopy, ATG/DTG, FTIR, SEM-EDX, BET and FRX techniques.

Article Synopsis
- This study compares the behavior of two plant species and their extracts in synthesizing zinc oxide nanoparticles from zinc nitrate hexahydrate.
- Sugars, particularly glucose and sucrose, play a crucial role in this synthesis, comprising over 70% of the dried extract.
- The process can successfully occur at low temperatures (120°C) but requires a specific ratio of reactants to ensure the production of "clean" ZnO nanoparticles.

Article Synopsis
- Chickpeas and apricots are economically significant crops that suffer from severe fungal infections, traditionally managed with chemical fungicides that pose health and environmental risks.
- Myco-synthesized (from fungi) and bacteria-synthesized zinc oxide (ZnO) nanoparticles were compared for their antifungal effectiveness against specific pathogens affecting these crops.
- Results showed that myco-synthesized ZnO nanoparticles exhibited better antifungal properties at lower concentrations, highlighting the need for further research to enhance their application in agriculture as sustainable alternatives to chemical fungicides.

ZnO-doped CuO nanocomposites (CuO-ZnO NPs) of 1, 3, and 5 mol% were prepared by the solution combustion method using ODH as a fuel (Oxlyl-hydrazide) at 500 °C and calcining at 1000 °C for two hours and the Structural, photocatalytic, and electrochemical properties were investigated by experimental and theoretical methods. X-ray diffraction (XRD) patterns revealed a crystallite size (D) range of 25 to 31 nm for pure CuO and 1, 3, and 5 mol% CuO-ZnO NPs. According to calculations, the optical energy band gap (Eg) of the NPs is between 2.
