Stimuli-responsive release triggers

Definition

Stimuli-responsive release triggers are mechanisms that enable the controlled release of therapeutic agents, such as growth factors, in response to specific environmental cues or changes. These triggers can be activated by various stimuli, including pH changes, temperature fluctuations, light exposure, or the presence of specific biomolecules, allowing for targeted delivery and enhanced therapeutic efficacy.
