Harnessing Nanotechnology to Enhance Essential Oil Applications

Essential oils (EOs) are versatile natural compounds with significant antimicrobial, antioxidant, antifungal, and therapeutic properties, making them valuable in industries such as food preservation, agriculture, and healthcare. However, their inherent volatility, low water solubility, and susceptibility to environmental degradation limit their direct applications. Nanotechnology offers transformative solutions to these challenges, enhancing the stability, bioavailability, and efficacy of EOs through innovative nano systems such as nano emulsions, encapsulations, and nanocomposites. This study explores the integration of nanotechnology with essential oils, emphasizing advanced preparation techniques, physicochemical properties, and diverse applications. It highlights sustainable approaches, including eco-friendly synthesis and biodegradable carriers, which align with global trends toward green chemistry. By addressing key challenges and proposing future directions, this research underscores the potential of EO nano systems to deliver multifunctional and environmentally conscious solutions for global challenges such as food security, antimicrobial resistance, and sustainable agriculture.
