Abstract

Nanoparticles (NPs) have attracted significant interest due to their unique chemical and physical properties. In this context, biogenic synthesis has emerged as a promising alternative, utilizing natural pathways (e.g., microorganisms and plants) to produce biomolecules such as polyphenols, vitamins, amino acids, and carbohydrates that can reduce and stabilize NP production. However, significant knowledge gaps remain, particularly regarding the interaction between biomolecules and metals, and their influence on the physicochemical properties of NPs. This review critically examines current biogenic synthesis methods and their applications in removing organic contaminants and inactivating microorganisms in water treatment. It also highlights the challenges and opportunities in this field. In terms of scalability, there are significant limitations currently. The variability in the composition of biological extracts makes it difficult to achieve reproducibility and control over NP size and morphology. Additionally, production processes tend to be slow and yields which lower than conventional chemical methods. Optimizing influential parameters such as biomolecule concentration, temperature, and pH remains a challenge. Finally, the lack of studies on toxicity and long-term stability hinders large-scale implementation.

生物纳米颗粒:合成、表征、应用和扩大水处理的限制。
纳米粒子以其独特的物理和化学性质引起了人们的极大兴趣。在这种背景下,生物合成已经成为一种有前途的替代方法,利用自然途径(例如微生物和植物)生产生物分子,如多酚、维生素、氨基酸和碳水化合物,可以减少和稳定NP的产生。然而,重大的知识空白仍然存在,特别是关于生物分子和金属之间的相互作用,以及它们对NPs的物理化学性质的影响。本文综述了目前的生物合成方法及其在水处理中去除有机污染物和灭活微生物方面的应用。它也突出了这一领域的挑战和机遇。在可伸缩性方面,目前有很大的限制。生物提取物组成的可变性使其难以实现对NP大小和形态的再现性和控制。此外,生产过程往往很慢,产量低于传统的化学方法。优化生物分子浓度、温度和pH等有影响的参数仍然是一个挑战。最后,缺乏对毒性和长期稳定性的研究阻碍了大规模实施。
