Optical disc assemblies for performing assays
This invention relates to an optical disc assembly capable of receiving an insert upon which an analyte of interest may be disposed. The optical disc assembly can be read by an optical disc reader, such as by a standard CD or DVD reader, and the analyte disposed on the insert can be detected by the optical disc reader. The optical disc assembly may have one or more data layer in which operational information or assay information is encoded. Hologram may be used to encode operational information or assay information.
1. An optical disc assembly, comprising:
a cover portion comprising at least one insert having a surface capable of receiving an analyte which can be detected by an optical disc reader; and
a main portion comprising
an assay area, and
a data area containing encoded instructions that directs an optical disc reader to adjust its focus to the correct data layer in order to read analyte-specific signal elements disposed on the at least one insert.
2. The optical disc assembly of claim 1 , wherein the optical disc reader is a DVD reader.
3. The optical disc assembly of claim 1 , wherein the data area Further contains data used to adjust the firmware or flash components of the optical disc reader chipset so that the optical disc reader can correctly read and interpret analyte-specific signals.
4. The optical disc assembly of claim 1 , wherein the assay area comprises at least one operational structure.
5. The optical disc assembly of claim 4 , wherein the assay area is disposed on an outer portion of the optical disc assembly.
6. The optical disc assembly of claim 4 , wherein the at least one operational structure comprises a radial plane tracking feature to provide tracking information to the optical disc reader.
7. The optical disc assembly of claim 1 , wherein the data area comprises a first layer and a second layer, and wherein programs, instructions, or data can be stored in either the first layer or the second layer.
8. The optical disc assembly of claim 1 , wherein the data area comprises a first layer and a second layer, and wherein programs, instructions, or data are stored in both the first layer and the second layer.
9. The optical disc assembly of claim 1 , wherein the data area is disposed on an inner portion of the optical disc assembly.
10. The optical disc assembly of claim 1 , wherein the cover portion comprises an optical material, wherein the optical material affects a light beam from the optical disc reader so as to optimize the detection of the analyte-specific signal elements disposed on the at least one insert.
11. The optical disc assembly of claim 1 , wherein the optical material comprises polycarbonate, polymethyl acrylic, or glass.
12. The optical disc assembly of claim 1 , wherein the at least one insert comprises analyte-specific signal elements, and wherein the cover portion is configured such that the analyte-specific signal elements are physically segregated from operational structures in the cover portion or the main portion.
13. The optical disc assembly of claim 1 , further comprising at least one counterweight insert.
14. The optical disc assembly of claim 1 , wherein the cover portion and the main portion are affixed to each other such that they can be separated.
15. The optical disc assembly of claim 1 , wherein the at least one insert is inserted into the cover portion.
16. The optical disc assembly of claim 1 , wherein the at least one insert is attached to the cover portion.
17. A method of detecting an analyte held by an optical disc assembly comprising: a cover portion comprising at least one insert having a surface capable of receiving an analyte which can be detected by an optical disc reader; and a main portion comprising an assay area and a data area containing encoded instructions that directs an optical disc reader to adjust its focus to the correct data layer in order to read analyte-specific signal elements disposed on the at least one insert, the method comprising:
providing the optical disc assembly to the optical disc reader;
reading the optical disc assembly; and
obtaining a signal which is indicative of the presence of the analyte.
18. A kit for detecting an analyte, comprising: an insert having a surface capable of receiving an analyte and analyte-specific signal elements which can be detected by an optical disc reader; and a disc comprising a cover portion capable of receiving the insert, and further comprising a main portion comprising an assay area and a data area, the data area containing encoded instructions that directs an optical disc reader to adjust its focus to the correct data layer to enable the optical disc reader to read the analyte-specific signal elements disposed on the at least one insert.
