Non-contact temperature control system for microfluidic devices

DWPI Title: Non-contact temperature control system for microfluidic device comprises e.g. infrared emitter positioned to direct radiation to first surface of the device and reflector configured to reflect radiation collected from the second surface
Abstract: The present invention relates to a temperature control system for a microfluidic device. The system allows for non-contact heating by employing an infrared emitter. In some instances, the system can be used in conjunction with a centrifugal microfluidic device. Optionally, a mask can be implemented to provide selective heating of desired assay areas of the device.
Use: Used as non-contact temperature control system for a microfluidic device (claimed) and the microfluidic devices and systems is useful in diagnostics including particle quantification (cell counting, differential white blood cell count), sedimentation assays, sandwich assay, nucleic acid assays, agglutination assays, toxin assays or amplification assays.
Novelty: Non-contact temperature control system (3000) for a microfluidic device comprises an infrared emitter (3001)configured to emit at a wavelength of 1-5 μ m and positioned to direct radiation to a first surface of the device, a reflector (3002) configured to reflect radiation that is collected from a second surface of the device, where the second surface opposes the first surface and a focal point of the emitter configured to be positioned on or within an assay area, or a portion, of the device and the focal point of the emitter and a vertex of the reflector are aligned along a central axis.
