The invention defines an all-solid-contact ISE which comprises a transducer layer of carbon nanotubes which brings the sensing layer and conducting element into contact. The invention also defines a method for the preparation of said all-solid-contact ISE and the use of the same for the qualitative, quantitative or semi-quantitative analysis of analytes. Said all-solid-contact ISE makes it possible to detect or quantify highly diverse chemical species in a reliable and reproducible manner, with the added advantages derived from its simplicity and low construction cost.
