FU Yun-liang, ZHANG Tie-min, WANG Lin-mao. Detection of sulfonamide residues by surface plasmon resonance biosensor[J]. 2012, 31(12): 133-135. DOI: 10.13873/j.1000-97872012.12.043.
The surface plasmon resonance(SPR) optical bio-immune sensor is used for detecting the sulfamethazine residues
and it is based on the binding value between monoclonal antigen and antibody of sulfamethazine on the sensor chip surface
which can be used for the capability of quantitative detection for sulfamethazine.The binding values are measured as the concentrations of sulfamethazine are 0
