Superimposed Nanostructured Diffraction Gratings as High Capacity Barcodes for Biological and Chemical Applications

Superimposed Nanostructured Diffraction Gratings as High Capacity Barcodes for Biological and Chemical Applications
Superimposed Nanostructured Diffraction Gratings as High Capacity Barcodes for Biological and Chemical Applications

We describe a new non-contact high capacity optical tagging technique for bead based assays, based on the use of nanostructured barcodes. The tags are generated from a number of superimposed diffraction gratings. With one-dimensional diffraction, capacity for up to 68,000 distinguishable tags has been demonstrated, with a theoretical capacity of up to 109 tags. Extension into two dimensions increases this theoretical limit to 1021 tags.

Abstract


We describe a new non-contact high capacity optical tagging technique for bead based assays, based on the use of nanostructured barcodes. The tags are generated from a number of superimposed diffraction gratings. With one-dimensional diffraction, capacity for up to 68,000 distinguishable tags has been demonstrated, with a theoretical capacity of up to 109 tags. Extension into two dimensions increases this theoretical limit to 1021 tags.
