Abstract:
A substrate is provided that facilitates immobilization of nucleic acid molecules, including DNA molecules and RNA molecules. Also provided is a device that includes the substrate, which, for example, can be a chip. In addition, methods of using the substrate are provided, including, for example, methods of sequencing a DNA molecule anchored to the substrate, and methods for conducting the process of sequencing using such devices.
Abstract:
The present invention describes microfluidics being employed to achieve multiplex surface functionalization of nanosensor chips by selectively delivering probe molecules to individual nanosensors in an array, and microfluidics being employed to achieve delivery of a solution containing multiple analytes over individual nanosensors in an array, where each nanosensor was previously configured with a specific capture molecule.
Abstract:
The present invention includes methods, assays, and devices for assaying a sample to detect the presence, absence, or level of at least one analyte in a biological sample using a pan-antibody panel or multiplexed immunoassay, wherein at least one analyte is detected by two or more antibodies. Certain embodiments include the use of a microfluidic device in the immunoassay. Further embodiments of the invention include assays, methods, and devices to detect the presence, absence, or level of at least one analyte which is determined for a diagnostic or a scientific purpose. Still further embodiments of the invention include assays, methods, and devices to detect the presence, absence, or level of at least one analyte which is indicative of a condition or disease. Yet further embodiments of the invention include incorporating additional diagnostic techniques (e.g., PCR, RT-PCR, and DNA hybridization arrays) to the assays, device, and methods.

Abstract:
A chemostat (Figure 1) that includes a growth chamber having a plurality of compartments, where each of the compartments may be fluidly isolated from the rest of the growth chamber by one or more actuatable valves. The chemostat may also include a nutrient supply-line to supply growth medium to the growth chamber (s), and an output port to remove fluids from the growth chamber. Also, presented is a method to prevent biofilm formation in a growth chamber of the chemostat. The method may include the step of adding a lytic agent to an isolated portion of the growth chamber and re-uniting the isolated portion with the rest of the growth chamber.

Abstract:
This disclosure provides methods, systems, compositions, and kits for the multiplexed detection of a plurality of analytes in a sample. In some examples, this disclosure provides methods, systems, compositions, and kits wherein multiple analytes may be detected in a single sample volume by acquiring a cumulative measurement or measurements of at least one quantifiable component of a signal. In some cases, additional components of a signal, or additional signals (or components thereof) are also quantified. Each signal or component of a signal may be used to construct a coding scheme which can then be used to determine the presence or absence of any analyte.
