The emergence of technology to produce nanoparticles (1 nm – 100 nm in size) has drawn significant researchers’ interests. Nanoparticles can boost the antimicrobial, catalytic, optical, and electrical conductivity properties, which cannot be achieved by their corresponding bulk. Among other noble metal nanoparticles, silver nanoparticles (AgNPs) have attained a special emphasis in the industry due to their superior physical, chemical, and biological properties, closely linked to their shapes, sizes, and morphologies. Proper knowledge of these NPs is essential to maximise the potential of biosynthesised AgNPs in various applications while mitigating risks to humans and the environment. This paper aims to critically review the global consumption of AgNPs and compare the AgNPs synthesis between conventional methods (physical and chemical) and current trend method (biological). Related work, advantages, and drawbacks are also highlighted. Pertinently, this review extensively discusses the current application of AgNPs in various fields. Lastly, the challenges and prospects of biosynthesised AgNPs, including application safety, oxidation, and stability, commercialisation, and sustainability of resources towards a green environment, were discussed.

生产纳米粒子（尺寸为1 nm – 100 nm）的技术的出现引起了研究人员的极大兴趣。纳米颗粒可以增强抗微生物，催化，光学和电导率特性，而这是它们相应的体积无法实现的。在其他贵金属纳米粒子中，银纳米粒子（AgNPs）由于其优越的物理，化学和生物学特性，与它们的形状，大小和形态密切相关，因此在业界受到了特别的重视。对这些NP的正确了解对于最大程度地发挥生物合成的AgNP在各种应用中的潜力，同时降低对人类和环境的风险至关重要。本文旨在批判性地回顾全球AgNP的消费量，并比较传统方法（物理和化学）和当前趋势方法（生物）之间的AgNP合成。还强调了相关的工作，优点和缺点。与此相关，本综述广泛讨论了AgNPs在各个领域的当前应用。最后，讨论了生物合成AgNP的挑战和前景，包括应用安全性，氧化性和稳定性，商业化以及资源向绿色环境的可持续性。
