Programmed fabrication of bimetallic nanobarcodes for miniature multiplexing bioanalysis

Nanobarcodes with Morse code patterns are fabricated by a programmed electrochemical deposition process. These bimetallic nanobarcodes are stable and easy to decode using optical or electrical devices. Their discretionally patterned codes offer mass memory capacity for information carriers. They show promising features as probe molecules' carriers in multiplexing bioanalysis.
