Abstract: Described herein are systems and methods for the detection of and/or determination of a measure of the concentration of analyte molecules or particles in a fluid sample. In some cases, the systems and methods employ techniques to reduce or limit the negative effects associated with non-specific binding events. Certain methods of the present invention involve associating the analyte molecules at least a first type of binding ligand and at least a second type of binding ligand, and spatially segregating the analyte molecules into a plurality of locations on a surface. The presence of an analyte molecule at or in a location may be determined by determining the presence of both the first type of binding ligand and the second type of binding ligand.

Abstract: Certain embodiments of the present invention relate to the preparation of microbeads that exhibit a "turn on" fluorescence response within seconds of exposure to an analyte vapor (e.g., a chemical warfare agent or a reactive stimulant). This sensing approach is modeled after the mechanism for inhibition of acetylcholinesterase enzyme activity, and utilizes a specific and irreversible reaction between phosphonyl halides and a fluorescent indicator. The present invention also relates to a sensor and a method for sensing an analyte through detection of changes in the fluorescing properties of the inventive microbeads.

Abstract: The present invention is directed to a method and apparatus for detecting and analyzing cell migration. More specifically, the present invention is directed to novel technology for analyzing cellular movement, including whole cell migration and subcellular component movement. Cells are distributed onto a substrate and monitored for migration or movement. According to one embodiment, when a labelled cell or portion of a cell passes over one of the delineations between detection units, such as individual fibers in a fiber optic bundle, the label causes a large intensity increase, which stays for a given "residence time" until the cell departs from the detection unit. Each cell is disposed over at least one detection unit.

Abstract: The present invention provides a novel cross-reactive sensor system utilizing cross-reactive recognition elements. In the inventive system, each of said one or more cross-reactive recognition elements is capable of interacting with more than one species of liquid analyte of interest, whereby each of said one or more cross-reactive recognition elements reacts in a different manner with each of said one or more species of liquid analytes of interest to produce a detectable agent of each analyte of interest, whereby said detectable agent is analyzed and the information is processed for data acquisition and interpretation. In certain preferred embodiments, the detectable agent and/or change is detected directly, while in certain other preferred embodiments, the detectable agent and/or change is detected with the help of a transducing agent capable of relaying information about each detectable agent generated for each of said species of liquid analyte of interest, whereby said information is processed for data acquisition and interpretation. The present invention also provides method for the analysis of analytes comprising contacting one or more analytes with the inventive system described above.

Abstract: A microsphere-based analytic chemistry system is disclosed in which self-encoding microspheres having distinct characteristic optical response signatures to specific target analytes may be mixed together while the ability is retained to identify the sensor type and location of each sensor in a random dispersion of large numbers of such sensors in a sensor array using an optically interrogatable encoding scheme. An optical fiber bundle sensor is also disclosed in which individual microsphere sensors are disposed in microwells at a distal end of the fiber bundle and are optically coupled to discrete fibers or groups of fibers within the bundle. The identities of the individual sensors in the array are self-encoded by exposing the array to a reference analyte while illuminating the array with excitation light energy. A single sensor array may carry thousands of discrete sensing elements whose combined signal provides for substantial improvements in sensor detection limits, response times and signal-to-noise ratios.

Abstract: The present disclosure, among other things, provides methodologies for quantifying targets of interest in samples by 1) capturing single target entities on individual solid phase particles in a manner that permits that those particles that contain captured targets to be optically distinguished from those that do not, and 2) optically analyzing the particles so that those with captured target entities are "counted". In some embodiments, provided methods and compositions in the present application comprise a population of particles including one or more sub-populations distinguishable from one another.

Abstract: The present invention generally relates, in certain aspects, to relatively small devices applied to the skin, modular systems, and methods of use thereof. In some aspects, the device is constructed and arranged to have more than one module. For instance, the device may have a module for delivering to and/or withdrawing fluid from the skin and/or beneath the skin of a subject and a module for transmitting a signal indicative of the fluid delivered to and/or withdrawn from the skin and/or beneath the skin of the subject, a module for analyzing a fluid withdrawn from the skin and/or beneath the skin of the subject, or the like. In some embodiments, the modules are connectable and/or detachable from each other, and in some cases, the connections and/or detachments may be performed while the device is in contact with the subject, e.g., while affixed to the subject. In some embodiments, the device may be repeatedly applicable to the skin of the subject to deliver to and/or withdraw fluid from the skin and/or beneath the skin of a subject, e.g., at the same location, or at different locations on the skin of the subject. In some aspects, the devices may be self-contained and/or have a relatively small size, and in some cases, the device may be sized such that it is wearable and/or able to be carried by a subject. For example, the device may have a mass and/or dimensions that allow the device to be carried or worn by a subject for various periods of time, e.g., at least about an hour, at least about a day, at least about a week, etc., or no more than about an hour, no more than about 10 min, etc.

Abstract: The present invention generally relates, in certain aspects, to systems and methods for application to the skin, and control of actuation, delivery, and/or perception thereof. For example, certain aspects of the invention are generally directed to devices for delivering to and/or withdrawing fluid or from subjects, e.g., to or from the skin and/or beneath the skin. In one aspect, the delivery and/or withdrawal of fluid is at least partially obscured. For example, the obscuration may be by time, and/or by sensory obscuration (e.g., by providing tactile, olfactory, auditory, and/or visual sensations). Certain aspects of the invention are generally directed to devices able to automatically deliver to and/or withdraw fluid from the skin and/or beneath the skin after activation, e.g., where the fluid is delivered and/or withdrawn without the need for any additional intervention. The devices may be activated by any suitable technique. In other aspects, a device may be contained in a package, and when removed from the package, the device may be constructed and arranged to be able to deliver and/or withdraw fluid when the device is applied to the skin, and in some cases, automatically and/or without any further intervention by the subject or another person.
