Stimuli-responsive cargo release

Stimuli-responsive cargo release refers to the engineering of drug delivery systems that release therapeutic agents in response to specific physiological or externally applied stimuli, such as pH changes, enzymatic activity, redox potential, temperature, light, or magnetic fields. These smart carriers aim to improve the spatial and temporal control of drug delivery, increasing efficacy and reducing side effects, particularly in applications such as cancer therapy. The strategy is implemented using a variety of materials (nanoparticles, polymers, liposomes, dendrimers), and the trigger for release is often chosen to exploit unique features of diseased tissue (e.g., acidic tumor microenvironment, overexpressed enzymes). While this approach is promising and widely researched, it is not a molecular drug target itself, but a property engineered into delivery vehicles.
