摘要

A novel micro surface plasmon resonance (SPR) sensor with multiple sensing areas was designed and fabricated, which realized the joint detection of various early liver cancer markers simultaneously. The SPR sensor has two sensing areas constructed by different metal layers to realize the separation of resonance peaks, which makes it possible to detect multiple substances by one single sensor. Then the two sensing regions were modified by “monoclonal antibody - AFP - polyclonal antibody” and “DNA probe - miRNA-125b - S9.6 antibody” respectively. These two sandwich structures enhance the specific detection of Alpha-fetoprotein (AFP) and miRNA-125b. The feasibility of the micro SPR sensor for joint diagnosis of early liver cancer markers was verified.
