The development of nanotechnology, in particular metal oxide nanoparticles, has captured immense scientific attention in the global arena due to their unique properties leading to their unique diverse applications. But the use of toxic precursors and high operational cost make existing methodologies inefficient for synthesising metal oxide nanoparticles (MONPs). Biogenic synthesis of MONPs has been hailed as a more sustainable approach for the synthesis of NPs due to its alignment with the principles of green chemistry. Microorganisms (bacteria, yeast, algae), animal sources (silk, fur, etc.), and plants are effective, low-cost, and eco-friendly means of synthesizing MONPs since they possess a high bio-reduction abilities to produce NPs of various shapes and sizes. The current review encompasses recent advancements in the field of plant-mediated MONP synthesis and characterisation. The detailed evaluation of various synthesis processes and parameters, key influencing factors affecting the synthesis efficiency and product morphology, practical applications with insight into the associated limitations and challenges presents a valuable database that will be helpful in developing alternative prospects and potential engineering applications.
纳米技术的发展，尤其是金属氧化物纳米颗粒的发展，因其独特的性质和多样的应用而在全球范围内引起了极大的科学关注。但是，有毒前驱体的使用和高昂的操作成本使得现有的金属氧化物纳米颗粒（MONPs）合成方法效率低下。由于生物合成MONPs符合绿色化学原则，因此被誉为一种更具可持续性的纳米颗粒合成方法。微生物（细菌、酵母、藻类）、动物来源（丝绸、皮毛等）和植物是合成MONPs的有效、低成本且环保的手段，因为它们具有很高的生物还原能力，能够生产各种形状和尺寸的纳米颗粒。本综述涵盖了植物介导的MONP合成与表征领域的最新进展。对各种合成过程和参数、影响合成效率和产物形态的关键影响因素进行详细评估，以及对实际应用及其相关局限性和挑战的深入了解，提供了一个有价值的数据库，这将有助于开发替代前景和潜在的工程应用。
