Surface plasmon resonance (SPR) has been widely used in many fields because of its unique specificity, sensitivity, quantification, and no need to label the target molecule (label-free). In this technology, the ligand is immobilized on the surface of the metal film. When the analyte flows in the microfluidic channel and interacts with these ligands, SPR can monitor the reflected light intensity to determine the amount of the analyte or track the resonance angle shifts. So far, due to the accuracy and convenience of SPR, it has not only been used to study the interaction of proteins, peptides, small molecules, bacteria, etc. but also various types of SPR-based biosensors have been developed for clinically relevant biomarker development, food safety (pathogens and toxins), environmental monitoring (pollutants), etc.
