AI Technical Summary
Existing photodynamic therapy for gastrointestinal treatment suffers from insufficient optical penetration depth, cumbersome operation, and difficulty in reaching curved areas, resulting in poor treatment effects. Furthermore, micron and nanoscale robots have poor stability in acidic and enzymatic environments, making it difficult to achieve precise drug delivery and activation.
A wireless magnetically controlled capsule device is designed, comprising a drug release component and a light source component. The magnetic control technology enables the directional movement of the capsule in the gastrointestinal tract and the precise activation of the photosensitive therapeutic agent. By utilizing the synergistic effect of the controlled-release layer and the light source component, the directional release and activation of the therapeutic agent at the lesion site is ensured, reducing damage to normal tissues.
It improves the targeting and therapeutic effect of photodynamic therapy, enhances the precision and safety of gastrointestinal disease treatment, reduces the risk of damage to normal tissues, and provides a more targeted and safer treatment method.
