Noi mikrosiru jutut oli vielä hauskoja silloin kun R. Luukanen-Kilde (rip) heitteli niitä ufokaappausjuttujensa väliin. Nyt e ei naurata enää, lähinnä nuo jutut kertoo vain maan surkeasta avoihoitopolitiikasta.
Elikkä olet denialisti vaikka asia on ihan julkisessa tiedossa ollut jo Coronapandemian lähtölaukauksesta lähtien
Specialized invisible dye, delivered along with a vaccine, could enable “on-patient” storage of vaccination history to save lives in regions where paper or digital records aren’t available.

Tarkoitushan näillä tulevaisuudessa on tietenkin valvoa ihmisten terveystietoja ja asia liittyy tiiviisti suunniteltuihin "immuniteettipasseihin"
Kyse on hallinnon kontrollista . Kuka saa tehdä mitä jne.....
Kuten MIT kertoo sirutus on vielä kokeiluvaiheessa eikä sitä ole käytetty vielä minkään rokotteen yhteydessä
(ihan vain selvennykseksi näille pahimmille hörhöille tässä viimeisimmillä sivuilla )
To create an “on-patient,” decentralized medical record, the researchers developed a new type of copper-based quantum dots, which emit light in the near-infrared spectrum. The dots are only about 4 nanometers in diameter, but they are encapsulated in biocompatible microparticles that form spheres about 20 microns in diameter. This encapsulation allows the dye to remain in place, under the skin, after being injected.
The researchers designed their dye to be delivered by a microneedle patch rather than a traditional syringe and needle. Such patches are now being developed to deliver vaccines for measles, rubella, and other diseases, and the researchers showed that their dye could be easily incorporated into these patches.
The microneedles used in this study are made from a mixture of dissolvable sugar and a polymer called PVA, as well as the quantum-dot dye and the vaccine. When the patch is applied to the skin, the microneedles, which are 1.5 millimeters long, partially dissolve, releasing their payload within about two minutes.
By selectively loading microparticles into microneedles, the patches deliver a pattern in the skin that is invisible to the naked eye but can be scanned with a smartphone that has the infrared filter removed. The patch can be customized to imprint different patterns that correspond to the type of vaccine delivered.
“It’s possible someday that this ‘invisible’ approach could create new possibilities for data storage, biosensing, and vaccine applications that could improve how medical care is provided, particularly in the developing world,” Langer says.
Tests using human cadaver skin showed that the quantum-dot patterns could be detected by smartphone cameras after up to five years of simulated sun exposure.
The researchers also tested this vaccination strategy in rats, using microneedle patches that delivered the quantum dots along with a polio vaccine. They found that those rats generated an immune response similar to the response of rats that received a traditional injected polio vaccine.
“This study confirmed that incorporating the vaccine with the dye in the microneedle patches did not affect the efficacy of the vaccine or our ability to detect the dye,” Jaklenec says.
The researchers now plan to survey health care workers in developing nations in Africa to get input on the best way to implement this type of vaccination record keeping. They are also working on expanding the amount of data that can be encoded in a single pattern, allowing them to include information such as the date of vaccine administration and the lot number of the vaccine batch.
