Abstract: The invention generally relates to a system for isolating or separating a target from a sample. In certain aspects, processes performed by the target capture system include introducing a plurality of magnetic particles, in which a plurality of the particles include at least one binding moiety specific to a target, into a sample to form at least one target/particle complex and applying a magnetic field to isolate the magnetic particle/target complexes from the sample. The process starts at inputting a sample into the system and ends at delivering a capture target or nucleic acids of the target into a container for further analysis.

Abstract: Described is a method for sequencing a polynucleotide strand by sequencing by synthesis, the method including selecting a predetermined order of nucleotides to provide to a sequencing reaction, the order being selected to correlate with a predicted sequence for the polynucleotide strand; monitoring the reaction to detect incorporation of a nucleotide into a synthesised polynucleotide strand; wherein, in the event that nucleotide incorporation is detected, proceeding to provide the next nucleotide in the predetermined order. In the event that nucleotide incorporation is not detected, the predicted sequence for the polynucleotide strand may be revised and a new predetermined order of nucleotides selected, wherein the new predetermined order is selected to correlate with the revised predicted sequence. In this way, the sequencing reaction provides feedback to modify the order of nucleotides provided, thereby improving the efficiency of the sequencing reaction.
Abstract: The invention generally relates to conducting an assay on a sample that isolates a bacterium from the sample, in which the assay isolates as low as about 1 CFU/ml of bacteria in the sample.

Abstract: A method of monitoring amplification of a nucleic acid by providing a nucleic acid and an amplification mixture using the kit of isothermal reagents to a pH sensor or pH indicator, amplifying the nucleic acid using isothermal amplification, and detecting a change in pH due to the amplification using the pH sensor or pH indicator. The kit of reagents comprises a magnesium salt, a quaternary ammonium salt, and an alkali base.
Abstract: A device comprising an electrostatic discharge protection structure, an ion sensitive field effect transistor (ISFET) having a floating gate, and a sensing layer located above the floating gate. The device is configured such that the electrical impedance from the sensing layer to the electrostatic discharge protection structure is less than the electrical impedance from the sensing layer to the floating gate. The device can be fabricated in a standard CMOS process.
