To enhance the preservation of strawberries, a novel coating formulation was developed using chitosan (CH) and iron oxide (IO) nanoparticles (NPs) supplemented with ginger and garlic extracts and combined with varying concentrations of 1%, 2%, and 3% FeO NPs. The results of XRD revealed an average crystalline size of 48.1 nm for FeO NPs.

5-Fluorouracil (5-FU) is amongst the most commonly used antimetabolite chemotherapeutic agents in recent decades. However, its low bioavailability, short half-life, rapid metabolism and the development of drug resistance after chemotherapy limit its therapeutic efficiency. In this study, 5-FU applications as an anti-cancer drug for treating diverse types of cancers (e.

In the present work, for the first time, green chemically synthesized and stabilized CoO nanoparticles were employed for catalytic conversion of isopropyl alcohol to acetone by dehydrogenation of IPA. Plant extract of Rosmarinus officinalis was used as a reducing and stabilizing agent for this synthesis. The biosynthesized CoO nanoparticles were annealed at 450℃ followed by their physiochemical characterizations through XRD, SEM, AFM, and FTIR.

Biosynthesis has emerged as an exciting interface for assembling multifunctional metal oxide nanoparticles for diverse medicinal applications. Herein, biogenic nickel oxide (NiO-NPs) is synthesized by using floral extracts of () as a low cost, ecofriendly reducing and stabilizing agent. NiO-NPs were annealed at 300 °C, 400 °C and 500 °C while their physiochemical properties were established by HR-SEM/TEM, UV, XRD, FTIR, EDS, SAED and SQUID techniques.

Aqueous floral extracts of Callistemon viminalis were used to synthesize FeO nanoparticles (IONPs) which were intensively characterized through UV-vis, X-ray diffraction, HR-SEM/HR-TEM, Fourier- transform infrared spectroscopy (FTIR) and energy dispersive X-ray spectroscopy (EDS). Their physical properties were studied in response to different annealing temperatures. It was observed that the increase in the annealing temperature produced small-sized nanoparticles.
