Herein, we report a simple and inexpensive way for fabrication of ultramicroelectrode arrays (UMEAs) and the relative characterization methods. The fabrication of UMEAs involves only a few steps of handwork. Since only metal wires and epoxy are used through the fabrication process, it is supposed to be a quite straightforward method for preparing UMEAs. A dissolved oxygen (DO) sensor based on UMEAs was constructed. The detection of DO in different aqueous samples is fast, reliable and reproducible. The surface of UMEAs fabricated can be renewed simply by mechanically polishing or electrochemical treatment, which is of great advantage to practical applications.
