    摘要： A wetness sensor for an absorbent article that is formed from an ink is provided. The ink includes a proton-accepting chromogen and a proton-donating agent (or color developer). Prior to use, the ink is generally dry and in a protonated form so that it has a visible color. However, upon contact with bodily fluids (e.g., urine, fecal matter, mucus, menses, vaginal fluid, etc.), water in the fluid can lead to deprotonation of the chromogen, thereby resulting in a shift of the absorption maxima of the chromogen towards either the red (“bathochromic shift”) or blue end of the spectrum (“hypsochromic shift”). To increase the rate of the color change during use, the proton-donating agent is an aliphatic carboxylic acid that is highly soluble in the bodily fluid (e.g., urine), and therefore results in a color change that is very rapid and may be detected within a relatively short period of time.

    摘要： Hollow particles for use in various types of assay devices are provided. Due to their hollow or voided structure, the particles may exhibit a variety of beneficial properties. For instance, hollow particles are generally lightweight, and thus, relatively inexpensive in comparison to other types of particles. Hollow particles may also form a stable system without requiring refrigeration or rotation. In addition, hollow particles may possess enhanced light diffraction capabilities, which may be particularly beneficial in certain types of assay devices, e.g., diffraction-based assay devices.

    摘要： A membrane-based assay device for detecting the presence or quantity of an analyte residing in a test sample is provided. The device utilizes conjugated probes that contain a specific binding member for the analyte of interest. The specific binding member preferentially complexes with the analyte within a test sample when contacted therewith. Excess analyte that remains uncomplexed with the specific binding member undergoes non-specific binding, such as to a hydrophobic domain. As a result, the ability of the uncomplexed analyte to compete with the complexed analyte at the detection zone of the device is restricted. Thus, the incidence of “false negatives” is limited in a simple, efficient, and relatively inexpensive manner.

    摘要： A flow-through assay device for detecting the presence or quantity of an analyte residing in a test sample is provided. The device utilizes a scavenging zone that contains a capture reagent for the analyte of interest. The capture reagent may capture a quantity of the analyte that is less than or equal to a predefined base quantity of the analyte, such as a quantity considered “normal” for a particular test sample. Thus, the capture reagent is able to prevent some of the analyte from being detected. In this manner, the sensitivity of the assay device may be reduced in a simple, inexpensive, yet effective manner.
