Laser light detects colorectal cancer biomarker in blood within minutes

Researchers developed a laser-based method to detect colorectal cancer biomarkers in blood within minutes. The approach picks up faint tumor signals that even precise antibody techniques struggle to capture.

• Method uses laser light to detect colorectal cancer biomarker in blood
• Results are obtained in minutes instead of lengthy lab analysis
• Approach captures faint tumor signals that antibodies miss
