After that, using a low-frequency ultrasound, we explode the nanobubbles, and thereby the tumor.” Dr. Tali IlovitshBursting Bubbles – and TumorsDr. Tali Ilovitsh: “Our new technology makes it possible, in a relatively simple way, to inject nanobubbles into the bloodstream, which then congregate around the cancerous tumor.After that, using a low-frequency ultrasound, we explode the nanobubbles, and thereby the tumor.”The researchers explain that today, the prevalent method of cancer treatment is surgical removal of the tumor, in combination with complementary treatments such as chemotherapy and immunotherapy.“The combination of nanobubbles and low frequency ultrasound waves provides a more specific targeting of the area of the tumor and reduces off-target toxicity."In the experiment, which used an animal model, the researchers were able to destroy the tumor by injecting nanobubbles into the bloodstream (as opposed to what has been until now, which is the local injection of microbubbles into the tumor itself), in combination with low-frequency ultrasound waves, with minimal off-target effects.“The combination of nanobubbles and low frequency ultrasound waves provides a more specific targeting of the area of the tumor, and reduces off-target toxicity," explains Dr. Ilovitsh."
