• the preparation of berberine (BBR) in nanoformulation to enhance its solubility and increase its antibacterial effectiveness against hospital-acquired infections. BBR nanoparticles (BBR NPs) were formed by antisolvent precipitation (ASP) using glycerol as a safe organic solvent. UV–vis absorption

• (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
