Abstract:
1. An interferometric detection device comprising: (a) a microfluidic chip with a sensing area, (b) a coherent light source positioned to direct a beam along an optical train toward said sensing area to generate a back-scattering light pattern; (c) a photodetector configured to detect the back-scattering light pattern; and (d) an optical enclosure containing a medium through which said optical train travels to the chip; wherein the device is configured to maintain a temperature of said sensing area within 20 m° C. of a first target temperature and to maintain a temperature of the medium within 500 m° C. of a second target temperature under conditions in which ambient temperature changes from 0.1° C. to 5° C. over 5 minutes.
