Title: Surface Plasmon Resonance detection system with integrated triggering of data acquisition
Inventor: FONSECA JOAO GARCIA DA
IPC: B01L3/00
Filed: 2009-12-22
Abstract: A system for detecting the presence of an analyte in a moving substrate or sample handling device is disclosed, providing integrated triggering of data acquisition. In particular, a Surface Plasmon Resonance "lab on a disk" reader system is disclosed. A substrate 10 defines a detection zone 12 which is arranged to immobilize target molecules on a metallic surface so that it can be detected using the Surface Plasmon Resonance effect. A radiation source 14 illuminates a portion of the surface 16 of the substrate. A detector module 18 receives reflected radiation from the substrate 10. An electric drive 4 is coupled to a drive shaft 6 to move the substrate and the source relative to each other such that the illuminated portion moves over the substrate. The detector module 18 comprises a trigger detector (26, Fig 2) and a data acquisition detector (28, Fig 2). A trigger signal is generated indicative of Surface Plasmon Resonance occurring in the illuminated portion. Data acquisition is triggered from the detector in response to the trigger signal of data from which a change in local refractive index at the detection surface is determinable.
