Global concern about petroleum hydrocarbon pollution has intensified and gained scientific interest due to its noxious nature, high persistence in environmental matrices, and low degradability. One way to address this is by combining remediation techniques that could overcome the constraints of traditional physio-chemical and biological remediation strategies. The upgraded concept of bioremediation to nano-bioremediation in this direction offers an efficient, economical, and eco-friendly approach to mitigate petroleum contaminants. Here, we review the unique attributes of different types of nanoparticles and their synthesis procedures in remediating various petroleum pollutants. This review also highlights the microbial interaction with different metallic nanoparticles and their consequential alteration in microbial as well as enzymatic activity which expedites the remediating process. Besides, the latter part of the review explores the application of petroleum hydrocarbon degradation and the application of nano supports as immobilizing agents for microbes and enzymes. Further, the challenges and the future prospects of nano-bioremediation have also been discussed.
全球对石油烃污染的关注因污染物的毒性、在环境基质中的持久性和低降解性而加剧，并引起了科学界的兴趣。解决这一问题的一种方法是结合修复技术，这些技术可以克服传统理化和生物修复策略的限制。朝着这个方向，生物修复的升级概念到纳米生物修复提供了一种高效、经济和环保的方法来减轻石油污染物。在这里，我们回顾了不同类型的纳米粒子的独特属性及其在修复各种石油污染物方面的合成方法。本综述还强调了微生物与不同金属纳米粒子的相互作用及其对微生物和酶活性的后续改变，从而加速了修复过程。此外，本综述的后半部分探讨了石油烃降解的应用和纳米载体作为微生物和酶的固定化剂的应用。此外，还讨论了纳米生物修复的挑战和未来前景。
