Abstract

Industrial wastewater, particularly antibiotic-laden effluents, poses a significant environmental threat, necessitating efficient and sustainable remediation strategies. In this study, ZnO/Au nanocomposites were synthesized using Urtica dioica extract (ZnO/Au@UDE NCs), offering an eco-friendly alternative to conventional chemical methods. The NCs exhibited well-defined spherical and oval morphologies (40-50 nm), as confirmed by FTIR, TEM, and XRD analyses. Their photocatalytic efficiency in degrading penicillin G was optimized by adjusting key parameters, achieving rapid degradation within 130 min. The incorporation of gold nanoparticles significantly enhanced the electron-hole separation, thereby improving photocatalytic performance. Furthermore, ZnO/Au@UDE NCs demonstrated potent antibacterial activity against Escherichia coli and Pseudomonas aeruginosa (MIC: 125 µg/ml) and exhibited strong antioxidant and anticancer properties, with IC50 values of 72.49 µg/ml for MCF-7 and 23.63 µg/ml for AGS cancer cells. The combined photocatalytic and biological functionalities highlight the potential of these NCs for environmental remediation and biomedical applications, demonstrating a sustainable and multifunctional approach to nanomaterial development.

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.
