Laser light enables detection of colorectal cancer biomarker in blood within minutes
Key Points
Researchers often use antibodies to detect specific molecules or biological markers because they are remarkably precise at recognizing their targets. However, finding the faint signals of cancer in blood samples is a challenge even for the most reliable techniques.
