Background: As the world grapples with increasing agricultural demands and unpredictable environmental stressors, there is a pressing need to improve plant resilience. Therefore, understanding the pioneering role of nanoparticles in alleviating plant stress is crucial for developing stress-resilient varieties to enhance food secure world. Nanoparticles have unique physical and chemical properties, and demonstrate their potential to enhance plant growth, nutrient utilization, and stress tolerance. This review delves into the mechanistic insights of nanoparticle-plant interactions, highlighting how these tiny particles can mitigate diverse stressors such as drought, salinity, and heavy metal toxicity. The action of different types of nanoparticles, including metal, carbon-based, and biogenic nanoparticles, are discussed in the context of their interaction with plant physiology and stress responses.This article also explores the potential drawbacks and environmental implications of nanoparticle use, emphasizing the need for responsible and sustainable applications. Therefore, this study aimed to offer exciting possibilities for managing both biotic and abiotic stress in plant species, from improving water-use efficiency and stress resilience via nanotechnology.Future research directions are suggested, focusing on nano-bioengineering and precision agriculture to create stress-resilient crops and enhance food security. Through the lens of interdisciplinary research, this paper underscores the significance of nanoparticles as innovative tools in the realm of agriculture, catalyzing a paradigm shift towards sustainable and stress-resilient farming systems.Aims: As the world grapples with increasing agricultural demands and unpredictable environmental stressors, there is a pressing need to improve plant resilience.
