Implication
Review highlights structural adaptations of pH-responsive nanoparticles across physiological gradients, indicating potential for active, site-specific drug release.
Key Points
- To evaluate environmentally responsive nanoparticle designs, focusing on mechanisms that exploit physiological and pathological pH gradients for targeted drug delivery.
- Synthesized literature on transitioning from passive first-generation nanoparticles to multifunctional, stimuli-responsive platforms.
- Analyzed structural transformations triggered by variations in pH across distinct organs, tissues, and subcellular compartments.
- Identified that pH-triggered physicochemical alterations—including swelling, dissociation, and surface charge switching—drive preferential drug release at target sites over healthy tissues.
- Demonstrated that utilizing local pH gradients transitions drug delivery platforms from passive carriers into responsive, sensing delivery vehicles.
