Abstract: The invention relates to a microfluidic system based on active control of flow resistance and balancing pressures in microfluidic channels and an improved method for disposable microfluidic devices and cartridges for use in, but not limited to, in-vitro diagnostics. The microfluidic system and device of the invention does not utilize mechanical moving parts to control the fluid flow and has no external fluidic connection to the instrument or fluidics controller.

Abstract: The invention relates to a microfluidic system based on active control of flow resistance and balancing pressures in microfluidic channels and an improved method for enhancing reactions with magnetic beads used in disposable microfluidic devices and cartridges for use in, but not limited to, in-vitro diagnostics. The microfluidic system and device of the invention does not utilize mechanical moving parts to control the fluid flow and has no external fluidic connection to the instrument or fluidics controller. The microfluidic system and device combines magnetic control over the movement of magnetic detection beads with electric field and convective enhancement of the movement of analytes and/or or reagentss surrounding the magnetic detection beads, thereby enabling movement of magnetic beads and analytes in the same direction or in different directions.

Abstract: A computerized automated diagnostic system including a cartridge configured to contain reagents for carrying out a diagnostic biological process and to receive a biological sample to be tested using the reagents and an instrument operative to interact with the cartridge to carry out multiple steps in the diagnostic biological process, the cartridge having multiple operative states including a non-functionalized state in which the cartridge does not include the reagents and does not include the biological sample, a partially functionalized state in which the cartridge does include the reagents and does include the biological sample and in which a carbon array assembly is mounted onto the cartridge and forms part of the cartridge and a fully functionalized state upon insertion of the cartridge, onto which the carbon array assembly is mounted, into clamped engagement with the instrument.

Abstract: A room-temperature shelf-storable electrophoretic array for use in a method of rapidly detecting the presence of at least one nucleic acid target molecule, from among a multiplicity of pre-selected nucleic acid target molecules, in a solution, the electrophoretic array including a multiplicity of immobilized, mutually spaced and mutually electrically separated microgel deposits, each of the multiplicity of immobilized mutually spaced and mutually electrically separated microgel deposits containing materials suitable for performing rolling circle amplification and binding of at least one of the multiplicity of pre-selected nucleic acid target molecules, each of the microgel deposits containing at least the following elements pre-anchored therein: an RCA probe specific to of at least one of the multiplicity of pre-selected nucleic acid target molecules and at least one primer.
