| abstract |
A device for reading a biochip including plural molecular recognition areas and plural optical positioning marks, associated with recognition areas. The device includes an optical head capable of projecting excitation light onto the biochip. A device is provided to effectuate relative displacement between the head and the biochip. A first optical analysis system is associated with the optical head to receive any light arriving from recognition areas. A second optical positioning system is associated with the optical head to receive any light from at least one guide track and/or optical positioning mark. A device is further provided for servocontrolling scanning by the optical head. Such a device may find particular application to biological and chemical analysis. |
