Advanced encapsulation technologies are pivotal for overcoming the volatility and instability of essential oils (EOs), thereby enhancing their efficacy as sustainable pesticides. This review systematically classifies and analyzes the mechanisms of innovative delivery systems, including mesoporous silica, polymeric nanoparticles, Pickering emulsions, and metal-organic frameworks engineered for the controlled release of EOs. Beyond outlining material design, we critically evaluate how these carriers modulate the physiological and biochemical interactions between EOs and target microbial, such as disrupting cellular membranes and interfering with metabolic enzymes. The review also comprehensively examines the practical applications of these formulations across food packaging, functional textiles, and sanitizing products. Furthermore, we address the crucial safety profiles of nano-/micro-formulations and discuss future directions focusing on scalability, environmental fate, and regulatory acceptance, providing a strategic roadmap for transitioning these technologies from laboratory research to real-world implementation.
