The invention, in its various aspects and embodiments, is a printed circuit board biosensor and a use for the same. The printed circuit board biosensor comprises a printed circuit board and a bioreporter. The printed circuit board includes a working electrode and a reference electrode formed thereon. The bioreporter is operably linked to the working electrode and capable of generating an electrochemical signal upon specifically recognizing a target molecule to be detected in a sample when subjected to an electrical potential applied across the working and reference electrodes. The printed circuit board biosensor may, in some embodiments, comprise part of a system for detecting a target molecule in a sample. Such a system might include, in addition to the biosensor, means for detecting the electrochemical signal when a potential is applied across at least one reference electrode and at least one working electrode and/or means for applying the electrical potential. The printed circuit board, and systems including the same, may also comprise kits when sold with instructions on their use in accordance with the present invention. |
