Abstract: In an embodiment, a method comprising: adding a composition comprising a photochromic dye to a sample having an opioid compound to form a reacted product; illuminating an electromagnetic ray having a wavelength between about 100 nm to about 600 nm on the photochromic dye; and detecting the opioid compound in the sample.

Abstract: The present disclosure relates to compositions, devices and methods for removing/filtering out microorganisms from a given fluid. The composition of the present invention comprises a non-water imbibing, biocompatible filament and at least one affinity ligand that is capable of capturing the microorganism(s). The invention also discloses methods for detection, diagnosis, and/or treatment.

Abstract: The present disclosure relates to heteromultivalent nucleic acid scaffolds and peptides, and to compositions comprising the scaffolds and peptides, and to methods for preparing and using the scaffolds and peptides. The present disclosure also relates to use of the scaffolds, peptides, and compositions for preventing or disrupting interactions between molecules, in particular protein-protein interactions, in particular for the treatment or prevention of disease, in particular cancer, such as breast cancer.

Abstract: A collapsible sample collection device with a novel, collapsible 3D capture open affinity net dispersed throughout the volume of the container, said net with tethered affinity moieties, is designed to address the need for low-cost, simple harvesting and concentration of diagnostic analytes that generally does not require any ancillary equipment. The collection device generally permits analytes of interest to be efficiently harvested from body fluid samples, in one step, concentrated, collapsed into a flat mailing size, and protected from degradation without the need for traditional cold chain technologies. The concentration factor will increase sensitivity by several orders of magnitude when coupled with any type of downstream analyte measurement, including point of care testing. The collection device, in various embodiments, obviates the need for handling transport or storage of the fluid portion of the body fluid sample (e.g. blood, urine, saliva, etc.

Abstract: Laser Capture Microdissection devices and methods are provided. A Laser Capture Microdissection device contains a transmissive film and a transfer film. The transmissive film includes a first material configured to transmit laser energy. The transfer film includes a second material configured to absorb UV-laser energy. The transfer film contains an absorptive substance to absorb UV-laser energy and convert it into heat.

Abstract: A liquid including an organic component, a stabilization component, and a preservation component is provided. The organic component, the stabilization component, and the preservation component are different components. The organic component present in the liquid includes a volatile organic solution with a refractive index of 1.5 or below. Further, the liquid is a visualization solution that provides a resolving power of a lens by 1/1.5.

Abstract: An embodiment relates to a reagent buffer comprising a zwitterionic sulfonic solution, a non-ionic surfactant solution, and a buffer solution, wherein the reagent buffer has a pH range of about 7.0 to about 8.0 and a circular dichroism with an absorbance peak more than 0 at 190 nm and 225 nm. In an embodiment, the reagent buffer is configured to be a reagent buffer for a lateral flow immunoassay for detection of COVID-19.
