Hmmm … this is an MIT article when a vaccine is injected that a dye invisible to the naked eye can be read by a specialized reader.
MIT researchers have now developed a novel way to record a patient’s vaccination history: storing the data in a pattern of dye, invisible to the naked eye, that is delivered under the skin at the same time as the vaccine.
“The researchers showed that their new dye, which consists of nanocrystals called quantum dots, can remain for at least five years under the skin, where it emits near-infrared light that can be detected by a specially equipped smartphone.”

In the event the article is removed in the future, you can download a PDF version of the story.
my son teaches Chemistry, I guarantee he wouldn’t. he will not drink a soft drink even
How do you download the PDF? I did not see a link. Am I missing something? Thank you for being a watchman!
