Solid and liquid green Ag nanoparticles based on banana peel extract as an eco‐friendly remedy for ringworm in pets

Abstract

Green chemistry‐based biowaste has been taken attention toward new components for many applications especially in dermatophytes of animals and humans. The main goal of this study is to assist the synthetic pathways; clean and large‐scale synthesis of silver nanoparticles is achieved as a promising alternative green technique with high efficiency, simplicity and less hazardous waste based on agro‐waste of banana peels extract powder. The preparation of silver nanoparticles is directly via solid‐state reaction and the liquid one based on the natural agro‐waste of banana peels under specific conditions for treating ringworm in pets. Ultraviolet (UV)‐visible spectroscopy, Fourier transform infrared spectroscopy (FT‐IR), and transmission electron microscope (TEM) were used to prove the prepared nanoparticles. A total of 30 samples from pets (dogs and cats) were subjected to mycological examination. Ten (33.3%) were culture positive, and 100% of the positive samples were Microsporum canis. In vitro antifungal activity against M. canis isolates using both the disc diffusion and the broth microdilution methods was evaluated. The significant results for solid silver nanoparticles (Ags1 and Ags2) than liquid Ag NPs (AgL) with p < 0.05 compared with itraconazole were observed. This biomaterial from waste could be used as a fast, simple, eco‐friendly, and efficient method to prepare Ag NPs on solid that can be applied in the veterinary sector against ringworm.

“…The cell-free filtrate of F. oxysporum did not show any specific bands’ overall spectra range. On the other hand, the spectrum of biosynthesis AgNPs showed a broad surface plasmon resonance (SPR) peak for AgNPs at around 450 nm which was affirmed by the color change from colorless to reddish-brown due to the excitation of surface plasmon resonance (SPR) phenomena of AgNPs [ 37 ].…”
