SPFS SENSOR EQUIPPED WITH MECHANISM PURIFYING NON-SPECIFICALLY ADSORPTIVE CONTAMINANTS

摘要

[Object] It is an object of the invention to provide a sensor area which can suppress a decrease in assay signal and an increase in assay blank in an SPFS measurement. [Solution] An SPFS sensor chip of the invention includes a purification area and a sensor area arranged upstream and downstream, respectively, relative to each other along a flow direction in a channel for surface plasmon-field enhanced fluorescence spectroscopy [SPFS].
