5 Key Takeaways

• 1

  Scientists developed an ultra-sensitive blood test that detects cancer-related microRNAs at sub-attomolar levels.

• 2

  The test identifies specific microRNAs linked to early tumor development, providing potential early warning signs of cancer.

• 3

  The optical sensing system uses second-harmonic generation and a layered structure with MoS₂ and quantum dots for detection.

• 4

  The method demonstrated stronger signal differences in lung cancer patients compared to standard RT-qPCR testing.

• 5

  This technology could enable early blood screenings for lung cancer and facilitate personalized treatment monitoring.
