Biochip and biochip reading device comprising a plurality of zones for molecular recognition



Biochip and biochip reading device comprising a plurality of zones for molecular recognition



Official Gazette of the United States Patent and Trademark Office Patents 1268(4)



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.
