Sonodynamic therapy (SDT) is a noninvasive ultrasound-triggered therapeutic strategy for site-specific treatment of tumors with great depth penetration such as breast cancer. Alfa Cytology offers cutting-edge research services and essential platforms to help you stay ahead in the development of sonodynamic therapy for breast cancer.
Solid tumor treatment relies heavily on chemotherapy, radiotherapy, surgical resection, and/or immunotherapy. Although many alternative non-invasive solid tumor therapies have been proposed over the years and continue to be tested in various settings, eradication of tumor cells remains a difficult task for current cancer treatments. In recent years, sonodynamic therapy (SDT) has become an effective method for breast cancer treatment. SDT is a non-invasive anti-cancer treatment using chemical sonosensitizers and high-intensity focused ultrasound. It works by using concentrated, high-intensity ultrasound beams to destroy or denature target cancer tissue. Photosensitizers accumulate highly specifically in tumor cells, release energy and generate reactive oxygen species (ROS) when activated in the presence of oxygen, leading to cancer cell toxicity. Cancer cells are particularly dependent on antioxidants, which makes them particularly susceptible to excess ROS.

Sonosensitizers have unique chemical and physical properties that are critical in determining their utility in certain applications. Traditional sonosensitizers are developed based on specific types of organic molecules and are divided into four major categories: porphyrins, phthalocyanines, xanthenes, and antitumor agents. The design, improvement and use of sonosensitizers are important aspects of sonodynamic therapy. Alfa Cytology can provide suitable sonosensitizers for the development of sonodynamic therapy for breast cancer, as well as help you develop new sonosensitizers.
