  • Publication number: 20230384221
    Abstract: Various embodiments may provide a method of illuminating a sample plane. The method may include providing an illumination subsystem, the illumination subsystem including an optical source and at least one lens, having an optic axis at an incident angle greater than 0° and less than 90° to a normal of the sample plane. The method may also include rotating the illumination subsystem about a pivot point between the optical source and the sample plane along the optic axis so that an adjusted illumination distribution generated by the illumination subsystem at the sample plane has greater symmetry compared to a reference illumination distribution generated by the illumination subsystem at the sample plane without the rotation about the pivot point.

  • Publication number: 20230347353
    Abstract: The present disclosure provides methods and systems for nucleic acid identification. Identification of a nucleic acid molecule may include generating, in a plurality of chambers, a plurality of double-stranded nucleic acid molecules, denaturing the double-stranded nucleic acid molecules, and detecting signals of the denaturation to generate one or more denaturation profiles. The one or more denaturation profiles may be usable to identify nucleic acid molecules. The methods and system described herein may provide for identification of multiple nucleic acid molecules from a single analysis.

  • Publication number: 20230035727
    Abstract: The present disclose provides methods for forming a microfluidic device. Methods for forming a microfluidic device may comprise providing a microfluidic structure and a film, treating a surface of the microfluidic structure, a surface of the film, or both with a solvent, subsequently pressing the microfluidic structure together with the film under a first heating condition to form the microfluidic device comprising the solvent, and applying a negative pressure to the microfluidic device under a second heating condition, which negative pressure is applied for a time period greater than 30 minutes or at a pressure less than 20 kilopascals (kPa) to remove at least a portion of the solvent. In some aspects, the present disclosure provides devices consistent with the methods herein.
