Sensor assembly, system, method and ph sensor

A system for isothermal amplification of a sample, the system comprising:

• an isothermal amplification assembly for carrying out an isothermal amplification process on the sample to produce at least one amplification product;
• and
• a sensor assembly for detecting the presence of the at least one amplification product, the sensor assembly comprising:
• an amplification product receiving region;
• and
• a first sensor responsive to the detection of indicator of the presence of at least one amplification product to provide a first signal, the first sensor comprising a sensing surface arranged to contact a sample in the amplification product receiving region,
• wherein the sensing surface comprises a first layer comprising a one-dimensional or two-dimensional material.

A method for determining the presence of an analyte in a sample, the method comprising:

• subjecting the sample to an isothermal amplification process, the isothermal amplification process producing at least one amplification product in the event that the analyte is present;
• providing the at least one amplification product to an amplification product receiving region;
• and
• detecting the presence of the at least one amplification product using a sensor assembly, the sensor assembly comprising a first sensor responsive to the detection of indicator of the presence of at least one amplification product to provide a first signal, the first sensor comprising a sensing surface arranged to contact a sample in the amplification product receiving region, wherein the sensing surface comprises a first layer comprising a one-dimensional or two-dimensional material.
