A team of scientists at the University of Arkansas successfully tested the ZAPS laser, which detects and destroys cancer cells inside the body directly through the skin.
According to one of the developers of the technology, Vladimir Zharov, the idea is to kill cancer cells before they start to metastasize, which is the leading cause of death in cancer.
Under the action of laser beams, malignant cells in the bloodstream absorb heat much more actively than healthy cells. The heat causes them to expand and then collapse.
“In one of the patients, ” says Vladimir Zharov, “we have destroyed 96% of tumor cells. At the same time, the laser did not work at full power. "
ZAPS has another distinct advantage: it can scan up to a liter of blood per hour, which is much faster than similar devices.
