Abstract
In this research, silver-decorated zinc oxide nanoparticles (ZnO-Ag NPs) were fabricated using Aesculus hippocastanum fruit extract (ZnO-Ag@AHFE NPs), and their catalytic and antimicrobial properties were studied. The nanoparticles were identified using XRD, TEM, and FT-IR analyses, which confirmed their spherical morphology, uniform structure, and particle sizes ranging from 50 to 70 nm. The ZnO-Ag@AHFE NPs illustrated high antibacterial performance compared to the extract and ZnO NPs alone, achieving a minimum inhibitory concentration (MIC) of 125 µg/mL against Escherichia coli and Pseudomonas aeruginosa. Additionally, the ZnO-Ag@AHFE NPs exhibited outstanding photocatalytic efficiency, degrading methylene blue and rhodamine B dyes by 97.6% and 94.3%, respectively, surpassing the performance of other catalysts. Antioxidant assays revealed that the nanoparticles inhibited 85% of DPPH free radicals, underscoring their potential in biological applications. This study presents a green method using A. hippocastanum fruit extract, offering an innovative approach to enhance the antibacterial, catalytic, and antioxidant properties of ZnO-Ag NPs. These findings highlight the transformative potential of green synthesis strategies for the development of multifunctional nanomaterials.
期刊介绍：
Bioprocess and Biosystems Engineering provides an international peer-reviewed forum to facilitate the discussion between engineering and biological science to find efficient solutions in the development and improvement of bioprocesses. The aim of the journal is to focus more attention on the multidisciplinary approaches for integrative bioprocess design. Of special interest are the rational manipulation of biosystems through metabolic engineering techniques to provide new biocatalysts as well as the model based design of bioprocesses (up-stream processing, bioreactor operation and downstream processing) that will lead to new and sustainable production processes.
Contributions are targeted at new approaches for rational and evolutive design of cellular systems by taking into account the environment and constraints of technical production processes, integration of recombinant technology and process design, as well as new hybrid intersections such as bioinformatics and process systems engineering. Manuscripts concerning the design, simulation, experimental validation, control, and economic as well as ecological evaluation of novel processes using biosystems or parts thereof (e.g., enzymes, microorganisms, mammalian cells, plant cells, or tissue), their related products, or technical devices are also encouraged.
The Editors will consider papers for publication based on novelty, their impact on biotechnological production and their contribution to the advancement of bioprocess and biosystems engineering science. Submission of papers dealing with routine aspects of bioprocess engineering (e.g., routine application of established methodologies, and description of established equipment) are discouraged.
