The encapsulation of bioactive compounds using pH-driven techniques has become a focal point of current research. Over the past 5 years, there has been a growing number of studies reporting the preparation of bioactive nanoparticles using pH-driven methods. However, the materials employed must possess pH- dependent solubility and high stability under varying acidic and basic conditions, which remains a significant limitation for the broader application and commercialization of pH-driven techniques. To surmount this restriction, it is imperative to optimize the pH-driven process, such as by incorporating stabilizers, identifying more optimal acidification points, and utilizing advanced acid-base regulators. Among these approaches, the combination of pH-driven technology with other techniques may prove to be a pivotal direction for advancing and promoting pH-driven technology. A comprehensive examination of the underlying mechanisms of pH-driven technology and a continuous process of optimization are fundamental to the advancement of pH-driven technology. In conclusion, the pH-driven encapsulation of bioactive compounds has a promising future.
