The anticancer potential of juglone, a naphthoquinone derived from walnut trees, has been extensively studied
however, its hydrophobicity and toxicity obstruct its therapeutic applications. This study aimed to overcome these challenges by encapsulating juglone into poly (lactic-co-glycolic acid) (PLGA) nanoparticles and evaluating their antiproliferative and apoptotic effects on HeLa cells. Juglone nanoparticles (JNP) were obtained by single emulsion solvent evaporation method. Its key physicochemical properties, such as particle size, zeta potential, drug loading, release yield, and encapsulation efficiency values were calculated as 207.45 ± 1.67 nm, -24.12 ± 2.21 mV, 47.80, 66.90 and 90.12%, respectively. JNP's antiproliferative effects were compared to those of free juglone on HeLa cells. The calculated IC
