International Classification:

G01N 33/544
G01N 33/84
G01N 27/327

Abstract:

A method for detecting an amount of an analyte in a solution includes adding an electrochemically active agent to the solution; applying an electrical current to a working electrode in contact with the solution to initiate the electrochemical redox reaction to change a pH of the solution from a first pH value to a second pH value; incubating the solution at the second pH value to allow the analyte to dissociate from the other molecules in the solution and to bind to a capture molecule connected to the working electrode via a linker; reacting a detecting probe with the analyte to allow the detecting probe to bind to the analyte, the detecting probe having a signaling tag attached thereto and configured to produce a signal at the second pH value; and collecting the signal to calculate the amount of the analyte in the solution.

Abstract:

The present disclosure relates to systems, devices, and methods for nucleic acid sequencing including polynucleotide strands having a nucleotide(s) modified with a redox label(s) attached thereto or capable of receiving the modified nucleotide(s) with a redox label(s) attached thereto. The systems, devices, and methods include a dielectric member with an attached translocating protein positioned between oxidizing and reducing electrodes. The oxidizing and reducing electrodes generate an electrical field extending to a reaction area where the translocation of the polynucleotide strand through the protein occurs such the modified nucleotide(s) with redox label(s) attached thereto are identified by changes in current flow in the oxidizing and reducing electrodes, wherein the changes identify electron transfer from the reducing electrode, to redox label, and to oxidizing electrode when the modified nucleotide with a redox label covalently bonded to the nucleoside base of the modified nucleotide of the polynucleotide strand is at the reaction area.

Abstract:

Device and methods for controlling pH or ionic gradient comprising a multisite array of feedback electrode sets comprising electrodes and pH sensing elements. The electrodes can include a reference electrode, counter electrode, and a working electrode. The device and methods iteratively select an amount of current and/or voltage to be applied to each working electrode, apply the selected amount of current and/or voltage to each working electrode to change pH of a solution close to the working electrode, and measure the signal output of the sensing element. The multisite array can include feedback and non-feedback electrode sets.

International Classification:

G01N 27/416
G01N 27/30

Abstract:

A sensor and a corresponding method measure the pH of a solution without using an external reference electrode. The pH sensor has at least one functionalized electrode with an attached first redox active molecule and an attached second redox active molecule that are differently sensitive to pH and oxidize/reduce at different voltages, and a difference in peaks of a response of the two molecules to applied electrical parameter is measured and correlated to a particular pH.
