Abstract
The present disclosure provides a system capable of dispensing DNA encoding solutions at controllable flow rates and in uniform patterns, allowing sufficient DNA to be deposited onto a substrate for subsequent detection and identification of the substrate. The disclosed dispensing system may also include a feedback mechanism capable of validating that sufficient DNA has been applied to a substrate so that a barcode may be generated, detected, and identified at a later time.
Claims20
A dispensing device comprising:
- a DNA reservoir configured to store encoding solution, wherein the encoding solution comprises coding strands of DNA that encode a characteristic about a plant and quantification strands of DNA comprising synthetic DNA oligomers conjugated with fluorescent dye molecules;
- and
- a spraying device configured to dispense the encoding solution on the plant;
- whereby the encoding solution is illuminated by a laser beam.

A method for measuring a quantity of a solution deposited on a plant comprising:
- focusing a laser beam, by a steering optic, at a part of the plant where an encoding solution has been deposited to excite the fluorescent dye molecules and cause the fluorescent dye molecules to emit fluorescent light,
- wherein the encoding solution comprises coding strands of DNA that encode a characteristic about the plant and quantification strands of DNA comprising synthetic DNA oligomers conjugated with fluorescent dye molecules, and
- wherein an intensity of fluorescent light emitted by the fluorescent dye molecules is directly proportional to an amount of coding strands of DNA deposited on the plant;
- collecting light by a collection and focusing optic;
- receiving the collected light by a photodetector;
- measuring the intensity of the fluorescent light by the photodetector;
- and
- determining whether the intensity of the received fluorescent light exceeds a threshold by the photodetector, thereby determining whether a sufficient amount of coding strands of DNA have been deposited on the plant.
