Abstract: Various embodiments are drawn to systems and methods for detecting an analyte of interest in a sample including an optical sensor, a capture probe attached to a surface of the optical sensor wherein the capture probe is capable of binding to the analyte to form a duplex or complex, and an antibody capable of binding to the analyte, duplex, or complex. In several embodiments, systems and methods further include a particle attached to the antibody or capable of binding to the antibody. In several embodiments, systems and methods for analyte detection feature one or more of the following: high detection sensitivity and specificity, scalability and multiplex capacity, ability to analyze large analytes, and ability to detect or measure multiple individual binding events in real-time.

Abstract: The invention provides methods and compositions for making and using collagen-glycosaminoglycan three-dimensional scaffolds immobilized with biomolecules that are spatially and temporally patterned. The method comprises adding benzophenone to a collagen-glycosaminoglycan three dimensional scaffold in the dark; adding one or more biomolecules to one or more areas of the collagen-glycosaminoglycan three-dimensional scaffold (which can be done optionally in the dark or in the light); and exposing the collagen-2glycosaminoglycan three-dimensional scaffold to light at a wavelength of about 350 to about 365 nm.

Abstract: A liquid chromatograph comprising a column coupled to a microring resonator array and methods of using the same are disclosed. The microring resonator array measures the bulk refractive index of the mobile phase and any sample injected onto and separated in the column. While carrying out the methods, the composition of a mobile phase passing through the chromatography column may remain substantially constant (isocratic elution) or it may vary (gradient elution). One or more microrings may comprise a covering to act as a thermal control. In addition, the sensor surface may be modified with some type of capture agent that can interact with one or more components in the sample.

Abstract: In one representative embodiment, a device includes a main microchannel and at least two other microchannels. The main microchannel defines a main fluid flow path and has an opening, and first and second microchannels defining a first and second fluid flow paths, respectively. The first fluid flow path is in fluidic communication with the main fluid flow path via the opening and forms a first angle relative to the main microchannel less than 90 degrees. The second microchannel defines a second fluid flow path in fluidic communication with the main fluid flow path via the opening and in fluidic communication with the first fluid flow path. The second microchannel forms a second angle relative to the main microchannel less than 90 degrees. The first and second microchannels form a third angle relative to one another, with the third angle being between 60 and 135 degrees.
