However, its poor aqueous solubility and limited bioavailability constrain its therapeutic utility. This study formulated nanoemulsions using marine (salmon oil) and plant (rapeseed oil) lipids to enhance the solubility and delivery of curcumin. The fatty acid profiles and lipid class distributions of both lipid sources were characterized. The resulting nanoemulsions prepared from salmon and rapeseed oils exhibited mean droplet diameters of approximately 170 nm and 220 nm, respectively, and remained physically stable for 30 days at 25 ◦ C. Notably, curcumin-loaded nanoemulsions displayed smaller droplet sizes than their unloaded counterparts, suggesting strong curcumin–lecithin interactions. In vitro cytotoxicity assays demonstrated that the curcumin-loaded nanoemulsions significantly reduced the proliferation of MCF-7 human breast cancer cells (p \u003C 0.001) . Collectively, these findings indicate that lipid-based nanoemulsions represent a promising delivery platform for curcumin in the context of breast cancer therapy.  \nKeywords: emulsions; breast cancer; MCF-7 cells; drug delivery; curcumin; in vitro  \n1. Introduction  \nOil-in-water (O/W) nanoemulsions are widely utilized across the food, pharmaceutical, and cosmetic industries for the delivery of hydrophobic bioactive compounds, including vitamins, omega-3 fatty acids, antimicrobials, antioxidants, phytosterols, and parenteral nutrition components [1,2] . These nanoemulsions are typically formulated by homogenizing an oil phase into an aqueous phase in the presence of water-soluble emulsifiers and stabilizers [3] . The distinctive characteristics of nanoemulsions, including small droplet size, surface charge, and large surface area, enable controlled release kinetics and confer excellent stability against coalescence, flocculation, and gravitational separation [4] . Nevertheless, the primary destabilization mechanism in these systems is Ostwald ripening, which occurs due to the diffusion of the dispersed phase through the continuous aqueous phase. This limitation can be mitigated by incorporating dispersed phases with very low aqueous solubility [5] .  \nNanoemulsion preparation can be accomplished through either low-energy (chemicalbased) or high-energy (mechanical-based) approaches [6] . Mechanical methods include ultrasound homogenization, high-pressure homogenization, and microfluidization. Surfactants play a critical role during emulsion formation by reducing interfacial tension between  \nthe oil and aqueous phases. Recently, phospholipids have gained attention for formulating pharmaceutically acceptable emulsions [7,8] .
