A chemiluminescent enzyme immunoassay method for quantifying antigen or antibody using 1,1′-oxalyldiimidazole (ODI) derivative or 1,1′-oxalyldisodium benzoate (ODB) derivative chemiluminescence (CL) detection was developed. Also, various enzymes were quantified using ODI derivative or DOB derivative CL detection. Fluorescent compound formed from a substrate (non-fluorescent compound) through the enzyme assay methods emitted CL when the fluorescent compound received energy from high-energy intermediate formed in ODI derivative or ODB derivative CL reaction.

Additives capable of controlling the reaction rate between substrate and enzyme to form a dye in enzyme assays with absorbance, chemiluminescence, and fluorescence are effective tools for optimizing enzyme assays. A dye can be formed rapidly from the reaction between enzyme and substrate in the presence of a catalyst. Using relatively high concentration of dye formed from the rapid reaction, trace levels of analytical materials can be quantified using absorbance, chemiluminecence and fluorescence detection. A dye can be formed from a relatively slow reaction between enzyme and substrate in the presence of a surfactant such as Triton X-100 and β-cyclodextrin. Using relatively low concentration of dye from the slow reaction, a high concentration of analytical material can be quantified without any dilution using absorbance, chemiluminescence, and fluorescence.

A biosensor for detecting an influenza A virus in a sample is disclosed, which includes: an influenza A virus antibody immobilized on a surface of Au—FeOcomposite; where the antibody binds with the influenza A virus in the sample, which converts 4-methylumbelliferyl-N-acetyl-α-D-neuraminic acid (MUNANA) to 4-methylumbelliferone (4-MU), where the 4-MU emits green light at pH of 5.5-6.5; and wherein the 4-MU emits blue light at pH of 9.3-11.3. In the biosensor, 1,1′-oxalyldiimidazole chemiluminescence (ODI-CL) reagent may be utilized to emit the blue and green lights.

Systems, methods, and devices are provided for generating visualizations of facial aging trends based on protein biomarker concentration information. Protein biomarker concentration information is generated by an immunoassay analyzer device. The protein biomarker concentration information is used to predict one or more facial aging trends, such as shiny skin, rough skin, uneven skin tone, eye wrinkles, photo-aging, loss of elasticity, or dilated pores. A visualization, such as a spider diagram or a face aging simulation, is generated and presented.

A chemiluminescent biosensor for detecting a coagulation factor in a blood sample including: a fluorogenic substrate for the coagulation factor, where the fluorogenic substrate includes a fluorescent dye; and a quencher conjugated with the fluorogenic substrate. The biosensor rapidly and accurately detects a coagulation factor in a blood sample including whole blood or plasma, thereby useful for minimizing or eliminating any reversal effect of anticoagulants.

An online system displays relevant products along with a video watched by a user in a synchronized manner, which allows the user to explore relevant content (e.g., products recommended to the user) while the user is watching the video. The online system receives a video including a sequence of video frames to be displayed to the user, and the video may be associated with a specific theme, e.g., a soccer game, and one or more video frames may include points of interest (referred as “Q points”). The online system detects or receives Q points associated with corresponding video frames, where a Q point in a video frame identifies an object of interest in the video frame. The online system also correlates user profile information of the user with the detected points to select relevant products tailored to the user.

A modular corrugated container integrates product cushioning with a product support surface formed from corrugated paper and having features that absorb transverse accelerations. The support surface has scored tabs that bend perpendicular to an interior support portion, forming feet that elevate the interior portion relative to a container bottom. The interior portion has perforations that absorb accelerations, such as a perforations formed around the outside perimeter of the location at which a product rests, perforations extending from corners of the support surface towards a central location of the support surface, and perforations at the scoring of the tabs. Voids formed along the tabs remove portions of the feet from contact with the container bottom to encourage constant dissemination of accelerations across the support surface.
