Orthogonal multi-readout identification of alloy nanowire barcodes

A multi-readout orthogonal detection of alloy nanowire barcodes is shown to maximize the identification power of such encoded nanostructures. The built-in redundancy associated with the simultaneous use of several independent and powerful readout modes, based on different distinct processes and phenomena, offers great promise for decoding barcoded nanomaterials and for meeting the major challenges of product protection and multiplexed biodetection.
