Detecting cancer cells in blood: Microfluidic device captures cancer cells with 90% efficiency
Circulating tumor cells (CTCs) refer to cancer cells that have broken off from a primary tumor. These tumor cells can travel through the blood in the circulatory system and lodge themselves in other organs to cause secondary tumors. Therefore, the detection and subsequent characterization of CTCs from blood can help in the clinical diagnosis and treatment of various cancers. However, the efficient capture of CTCs from blood has been proven to be difficult.
