Researchers build liquid biopsy chip that detects metastatic cancer cells in blood

A ‘liquid biopsy’ chip can trap and identify metastatic cancer cells in a small amount of blood drawn from a cancer patient. The breakthrough technology uses a simple mechanical method that has been shown to be more effective in trapping cancer cells than the microfluidic approach employed in many existing devices. The device captures cancer cells with antibodies attached to carbon nanotubes.
