The Quantum Dot Tattoo with LUCIFERase and theVenomous Snake FANGS Design

The Bill and Melinda Gates Foundation sought out a solution for vaccination records and funded MIT, which resulted in the microneedle vaccine patch – using LUCIFERase and the venomous snake fang design for the tiny needles to deliver the vaccine into the body leaving a mark in the body, at the same time, as proof.

The tags are incorporated in only some of the array of sugar-based microneedles on a patch. When the needles dissolve in about two minutes, they deliver the vaccine and leave the pattern of tags just under the skin, where they become something like a bar-code tattoo. Instead of ink, this highly specific medical record consists of copper-based quantum dots embedded in biocompatible, micron-scale capsules. Their near-infrared dye is invisible, but the pattern they set can be read and interpreted by a customized smartphone. [https://news.rice.edu/2019/12/18/quantum-dot-tattoos-hold-vaccination-record/]

“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.” (http://news.mit.edu/2019/storing-vaccine-history-skin-1218)
“Ultimately, we believe that this invisible, ‘on-body’ technology opens up new avenues for decentralized data storage and biosensing applications that could influence the way medical care is provided, especially in the developing world,” the researchers conclude.” (https://physicsworld.com/a/invisible-dye-embeds-vaccination-records-on-skin/)

“For several years now, we’ve been hearing about “microneedle patches” that deliver medication less painfully and more safely than hypodermic needles. A new take on the technology may allow them to work even better, by copying the structure of venomous snakes’ fangs.” (https://newatlas.com/snake-fang-microneedle-patch/60868/)
Inspired by the fangs of snakes, here, we report a patch-type MN platform that can deliver a variety of existing liquid drugs and vaccines into the skin in seconds by simply stamping the MN patch against the skin with gentle thumb pressure. (https://stm.sciencemag.org/content/11/503/eaaw3329 )
Microneedles are embedded in a Band-Aid-like device that is placed on the skin; a skilled nurse or technician is not required. [https://www.scientificamerican.com/article/invisible-ink-could-reveal-whether-kids-have-been-vaccinated/]
For now, the patches can only encode a handful of simple shapes. But adding more microneedles could make the designs more intricate, potentially conveying information about a vaccination’s date, dosage, lot number AND MORE. [ COMMENT: Notice the words, “AND MORE“. https://www.smithsonianmag.com/innovation/spiky-patch-could-invisibly-record-vaccination-history-under-skin-180973809/ ]
