Abstract

A method for tracking an item that includes the steps of (a) providing an item having a solid polymer material; (b) irradiating the item to create a spatial pattern of optical modifications in the polymer material, wherein the spatial pattern of optical modifications includes a code that indicates information; and (c) detecting the pattern of optical modifications, thereby determining the information.

Claims

1. A method for tracking an item, comprising:

(a) providing an item comprising a solid polymer material;

(b) irradiating the item to create a spatial pattern of optical modifications in the polymer material, wherein the spatial pattern of optical modifications comprises a code that indicates information; and

(c) detecting the pattern of optical modifications, thereby determining the information;

wherein the polymer material comprises (1) a polyimide material;

or (2) a silicon-based polymer.

2. The method claim 1, further comprising a step of carrying out a manipulation of the item, wherein the spatial pattern of optical modifications comprises a code that indicates at least one characteristic of the manipulation.

3. The method of claim 1, wherein the information that is determined comprises the at least one characteristic of the manipulation,

(1) wherein the manipulation is optionally selected from the group consisting of manufacturing the item, assessing quality of the item, using the item in a diagnostic assay, transiently modifying the item, and permanently modifying the item;

or

(2) wherein the at least one characteristic is optionally selected from the group consisting of the occurrence of the manipulation, the duration of the manipulation, a quality assessment of the manipulation, a number of times the manipulation is carried out or repeated, a location on the item where the manipulation occurred, and the identity of a modification of the item resulting from the manipulation.

4. The method of claim 1, wherein the optical modifications comprise increased absorption of light of one or more wavelengths, increased luminescence emission at one or more wavelengths, decreased absorption of light of one or more wavelengths, decreased luminescence emission at one or more wavelengths, a shift in wavelength of maximum light absorption, or a shift in wavelength of maximum luminescence emission, wherein the shift is optionally a bathochromic shift or a hypsochromic shift.

5. The method of claim 1, wherein the item is a flow cell.

6. The method of claim 5, further comprising a step of performing one or more steps of an assay of biological materials in the flow cell, wherein the spatial pattern of optical modifications comprises a code that indicates at least one characteristic of the one or more steps.

7. The method of claim 5, wherein the assay comprises a sequencing by synthesis protocol,

optionally wherein the at least one characteristic is selected from the group consisting of occurrence of the one or more steps, a number of the steps carried out, a number of cycles carried out to repeat the one or more steps, the location on the flow cell where the one or more steps occurred, and a quality assessment of the one or more steps, and

optionally further comprising selecting to carry out a further cycle of the sequencing by synthesis protocol based on the code that is determined.
