The promise of sonodynamic therapy
- 1.1k Downloads
Sonodynamic therapy is a potential cancer treatment modality that has been gaining support due to its effectiveness in both in vitro and in vivo studies. The therapeutic method combines ultrasonic irradiation with drugs known as sonosensitizers that amplify its ability to inflict preferential damage on malignant cells. This is based on the idea that ultrasonic waves have the ability to exhibit profound physical and chemical changes on cellular structure. The mechanisms by which ultrasound (US) disrupts cellular functioning can be further amplified when sonosensitizers are applied. Combining multiple sonosensitizers with US to create a substantial synergistic effect could be an effective method for destroying tumorigenic growths, while decreasing the likelihood of drug resistance.
