Molecular switches are dynamic entities capable of transitioning between distinct states in response to specific environmental or biological triggers. These triggers can include changes in pH, light exposure, temperature, redox conditions, or the presence of certain ions or biomolecules. The concept of molecular switching has significantly influenced the medical and pharmaceutical domain by providing a foundation for highly controlled diagnostic and therapeutic systems. The ability to precisely regulate biological responses has made molecular switches indispensable in the development of advanced drug delivery systems, real-time diagnostic tools, and personalized therapeutic interventions.

In the pharmaceutical sector, molecular switches have revolutionized drug delivery by enabling precise spatiotemporal control over the release of active pharmaceutical ingredients. One of the most widely explored triggers is pH, as pathological conditions like cancer and inflammation often create acidic microenvironments. pH-sensitive molecular switches are employed in nanoparticle-based drug carriers, which remain stable under normal physiological conditions but disassemble in acidic environments to release their payload. For example, the FPBC@SN nanoparticle system integrates a pH-sensitive molecular switch to target acidic cytoplasm in breast cancer cells.
This system releases both sorafenib, which induces ferroptosis, and an IDO inhibitor to enhance tumor immunity. By leveraging such switches, these systems reduce off-target effects and enhance the therapeutic index, addressing key challenges in oncology.
