Biochip reader with enhanced illumination and bioarray positioning apparatus

Title: Biochip reader with enhanced illumination and bioarray positioning apparatus

Abstract

A method of illumination and illumination apparatus are provided in a biochip reader. Illumination is provided by a non-collimated laser source or a light emitting diode (LED). The light is directed to opposing sides of a glass substrate by a pair of optical fiber bundles. The glass substrate carries a bioarray. Each of the optical fiber bundles are splayed out to make a fan, the fan being one fiber thick and defining a line of optical fiber faces. This process randomizes any non-uniformity in the illumination source, creating a more uniform illumination source. A respective divergent diffuser engages each row of optical fiber faces coupling and diffusing light substantially evenly through the opposing sides of the glass substrate to illuminate the bioarray supported by the glass substrate. The glass substrate functions as a secondary light guide. The divergent diffusers separate the optical fiber faces from the edges of the glass substrate, protecting the optical fibers from mechanical damage. A glass holder supports the glass substrate carrying the bioarray. The glass holder including a plastics springs member in spring contact engagement with the glass substrate for positioning said bioarray in a focal plane. Light also can be directed to opposing endsmore »« less

Patent Perov, Alexander ; Belgovskiy, Alexander I ; Mirzabekov, Andrei D

A biochip scanner device used to detect and acquire fluorescence signal data from biological microchips or biochips and method of use are provided. The biochip scanner device includes a laser for emitting a laser beam. A modulator, such as an optical chopper modulates the laser beam. A scanning head receives the modulated laser beam and a scanning mechanics coupled to the scanning head moves the scanning head relative to the biochip. An optical fiber delivers the modulated laser beam to the scanning head. The scanning head collects the fluorescence light from the biochip, launches it into the same optical fiber,more »« less
