| abstract |
The invention relates to an application of a surface plasmon resonance (SPR) technology in the detection of a human serum tumor marker, in particular to a method for applying the SPR technology to perform the clinic detection and the diagnosis of the human serum tumor marker. Therefore, the simultaneous detection of a plurality of serum tumor markers are realized, and the detection sensitivity and a clinical detection linear range are obviously improved. In addition, the invention also provides an SPR biological sensing chip which can be used for the method. |
