Abstract: Apparatus and techniques for electrokinetic loading of samples of interest into sub-micron-scale reaction chambers are described. Embodiments include an integrated device and related apparatus for analyzing samples in parallel. The integrated device may include at least one reaction chamber formed through a surface of the integrated device and configured to receive a sample of interest, such as a molecule of nucleic acid. The integrated device may further include electrodes patterned adjacent to the reaction chamber that produce one or more electric fields that assist loading the sample into the reaction chamber. The apparatus may further include a sample reservoir having a fluid seal with the surface of the integrated device and configured to hold a suspension containing the samples.

Abstract: Provided herein, in some embodiments, are rapid diagnostic tests to detect one or more target nucleic acid sequences (e.g., a nucleic acid sequence of one or more pathogens). In some embodiments, the pathogens are viral, bacterial, fungal, parasitic, or protozoan pathogens, such as SARS-CoV-2 or an influenza virus. Further embodiments provide methods of detecting genetic abnormalities. Diagnostic tests comprising a sample-collecting component, one or more reagents (e.g., lysis reagents, nucleic acid amplification reagents), and a detection component (e.g., a component comprising a lateral flow assay strip and/or a colorimetric assay) are provided.

Abstract: A method and apparatus for characterizing an optical element. The optical element is part of a laser and is mounted on a translation stage to scan the optical element transverse to an intracavity laser beam. A performance characteristic of the laser is recorded as a function of position of the optical element.

Abstract: Apparatus and methods for producing ultrashort optical pulses are described. A high-power, solid-state, passively mode-locked laser can be manufactured in a compact module that can be incorporated into a portable instrument for biological or chemical analyses. The pulsed laser may produce sub-100-ps optical pulses at a repetition rate commensurate with electronic data-acquisition rates. The optical pulses may excite samples in reaction chambers of the instrument, and be used to generate a reference clock for operating signal-acquisition and signal-processing electronics of the instrument.

Abstract: Embodiments described herein generally relate to apparatuses, cartridges, and pumps for peristaltic pumping of fluids and associated methods, systems, and devices. The pumping of fluids is, in certain cases, an important aspect of a variety of applications, such as bioanalytical applications (e.g., biological sample analysis, sequencing, identification). The inventive features described herein may, in some embodiments, provide an ability to pump fluids in ways that combine certain advantages of robotic fluid handling systems (e.g., automation, programmability, configurability, flexibility) with certain advantages of microfluidics (e.g., small fluid volumes with high fluid resolution, precision, monolithic consumables, limiting of the wetting of components to consumables).
