• inhibitory activity against pathogenic bacteria have been reported. In 2022, Nguyen et al. fabricated berberine nanoparticles (BerNPs) by antisolvent precipitation (ASP) using glycerol as a safe organic solvent and evaluated their antibacterial activity on S. aureus and E. coli O157:H7 [12].

• (EPN) and antisolvent precipitation (ASP)). Although top-down technologies have a high yield, they are energy-consuming and the obtained crystal size is inhomogeneous [26][27]. The ASP technique can modify crystal formation and particle size distributions [5]. Sahibzada et al. [26] reported that BBR
