Abstract: Apparatus and methods for the detection of proteins in biological fluids such as urine using a label-free assay is described. Specific proteins are detected by their binding to highly specific capture reagents such as SOMAmers that are attached to the surface of a substrate. Changes to these capture reagents and their local environment upon protein binding modify the behavior of color centers (e.g., fluorescence, ionization state, spin state, etc.) embedded in the substrate beneath the bound capture reagents. These changes can be read out, for example, optically or electrically, for an individual color center or as an average response of many color centers.

Abstract: Systems and methods for conducting surface-mediated chemical and/or biochemical reactions within an enclosed chamber are disclosed. Systems and methods of the present disclosure may be used in conducting hybridization reactions of biopolymers. In some examples, an improved method for mixing thin films of solutions in a hybridization chamber includes altering the direction of mixing at least once over the course of a reaction. In some examples, an improved method for mixing thin films of solutions in a hybridization chamber includes altering the speed of mixing at least once over the course of a reaction. In some examples, an improved method for mixing thin films of solutions in a hybridization chamber includes altering the speed of mixing and the direction of mixing at least once over the course of a reaction.

Abstract: Method and apparatus for determining internal structural properties of a polymer molecule by measuring the force required to translocate the molecule through the interface between two fluids. In some cases, the fluid interface may have a well-defined curvature, which may be held constant or otherwise controlled during translocation. In some cases, the translocating force may be modulated at one or more frequencies. In some cases, attachment of the molecule to a manipulator may be detected before or during translocation.
