A group of scientists has developed a novel microchip with DNA strands capable of latching onto dangerous cancer cells and capturing them for analysis, similar to how jellyfish tentacles capture prey. Researchers found that the strands successfully captured up to around 80% of leukemia cells that were passed through the device. "The chip we have developed is highly sensitive. From just a tiny amount of blood, the chip can detect and capture the small population of cancer cells responsible for cancer relapse," said researcher Weian Zhao, an assistant professor at the University of California, Irvine.
