Abstract

The present description discloses solid-contact (SC) electrodes that use mesoporous carbon such as colloid-imprinted mesoporous (CIM) carbon as the interlayer. The electrodes can be ion-selective electrodes (ISEs) or reference electrodes. The CIM carbon with the interconnected mesopores is used as the intermediate layer between the solid electron conductor, such as gold, and a membrane such as an ionophore-doped ion-selective membrane or a reference membrane. The disclosure includes methods of constructing solid contact electrodes such as SC-ISE or reference electrodes with a CIM carbon interlayer, and methods of using the electrodes to determine the quantity of an analyte in a sample. The description also includes disposable paper-based devices for measuring analytes in a sample.
