The MIT News article confirms that this has been successfully researched, and that the research was funded by the Bill & Melinda Gates Foundation.
From the article:
Several years ago, the MIT team set out to devise a method for recording vaccination information in a way that doesn’t require a centralized database or other infrastructure. Many vaccines, such as the vaccine for measles, mumps, and rubella (MMR), require multiple doses spaced out at certain intervals; without accurate records, children may not receive all of the necessary doses.
“In order to be protected against most pathogens, one needs multiple vaccinations,” Jaklenec says. “In some areas in the developing world, it can be very challenging to do this, as there is a lack of data about who has been vaccinated and whether they need additional shots or not.”

What do you doubt and what do you need confirmed?

It's probably going to be inadvisable to use this technology in vaccinations aimed at fundamentalist Christians:
Revelation 13:16-17 King James Version (KJV)

16 And he causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads:
17 And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name.

Thanks, I just wanted to make sure it was factual and also the post mentioned (Biocompatible near-infrared quantum dots delivered to the skin by microneedle patches record vaccination) I wanted to check if that was valid and if there is any more info about it. I did find this article about it but it is only for members. https://stm.sciencemag.org/content/11/523/eaay7162

Who would this be intended for? Is it for third world countries that do not have a means of tracking some people? Is there any information that it could also be used in Western Countries?

Is there any information that it could also be used in Western Countries?

Why did you post this in the Covid-19 forum? If there is a conspiracy theory revolving around this, then the thread should be about that. explaining the conspiracy theory and the claims of evidence the theory is using.
If you are making up your own conspiracy theory around this technology, then you need to honestly and concisely explain your theory.

random vague claims and speculation about whether "Western Countries" would ever use such a technology, looks like a disingenuous way of spreading conspiracy theories or panic. You said you were from the UK, do you have any evidence the UK is currently considering using this technology on it's population or any part of it's population? If not then there is no reason to assume it might happen anytime soon, so why fret about it?

Metabunk examines "specific claims of evidence". Your MIT article very specifically says, multiple times, it is for

“In areas where paper vaccination cards are often lost or do not exist at all, and electronic databases are unheard of, this technology could enable the rapid and anonymous detection of patient vaccination history

Western Countries have electronic databases.

we also need a link to your twitter screenshot in the Opening Post.

@Eleora "Developing world" (used in my quote above) and "third world" are synonyms, the former being preferred.

Claim: The devil will potentially use quantum-dot technology to put his mark on mankind, as foretold in the Book of Revelations
The Antichrist System Is Closer Than You May Think
The technological challenges of an antichrist marking and tracking system are being overcome today at an ever increasing pace and should be ominous signs for anyone, especially Bible believing Christians.
Microsoft co-founder Bill Gates wants to launch human-implantable capsules that have ‘digital certificates’ which can show who has been tested for the coronavirus and who has been vaccinated against it. The ‘digital certificates’ Gates was referring to are human-implantable ‘QUANTUM-DOT TATTOOS’ that researchers at MIT and Rice University are working on as a way to hold vaccination records. The quantum-dot tattoos involve applying dissolvable sugar-based microneedles that contain a vaccine and fluorescent copper-based ‘quantum dots’ embedded inside biocompatible, micron-scale capsules. After the microneedes dissolve under the skin, they leave the encapsulated quantum dots whose patterns can be read to identify the vaccine that was administered.

The MIT article is evidence that this technology can do that and is capable of being used with a near-universally administered vaccination, such as is expected for Covid-19.

It's kinda hard to debunk the theory as a whole without getting into a theological argument (and many churches have publications online that make the argument that this is theological bunk), but the technical claim is confirmed, I think.

The "Mark of the Beast" is a constant feature in religious-inspired conspiracy theories. Here's a protest in Texas from two days ago:

Metabunk 2020-04-18 21-33-27.jpg

ID2020 is an NGO that's advocating for the development of an easy-to-use digital ID, of which this quantum dot tattoo is a proposed example (but not, apparently, by ID2020). There's a great overview here, describing the nature and origin, and the Quantum Dot and Texas connection.


The non-profit, which does not work on embedded microchips, is falsely accused of being part of fictitious plans that allege Bill Gates supports mandatory vaccination and the implantation of microchips or “quantum dot tattoos” into patients.

The claims about Gates have been debunked by fact-checkers at Reuters, but ID2020 is not listed in the leading database of COVID-19 debunks.
A COVID-19 misinformation example.
Since mid-March, the outfit, which had an income of $1.4 million in the 2017 tax year, has been mentioned alongside false claims about Gates and COVID-19 in tens of thousands of social media postings, videos, and memes, amplified to millions after being shared by members of impassioned communities.

The ID2020 theory attracts attention, for example, from adherents of the QAnon conspiracy, the “alt-right”, objectors to 5G telecommunications, and Christians considering apocalyptic prophecies such as the “mark of the beast”.

Asked by TNH about the Gates and ID2020 conspiracy, Tedros praised the “extraordinary commitment” and sincerity of Bill and Melinda Gates and thanked them for their contribution.

A ‘wild ride’ starts with prolific conspiracy theorist Alex Jones

In a telephone interview with TNH, Gruener, the ID2020 CEO, said it had been a “wild ride” and she was “mystified”, adding: “I don’t know who’s behind this.” Gruener could, however, trace the beginnings of the firestorm back to October 2019.

A 23 October monologue by Alex Jones on the InfoWars website falsely alleged that an ID2020-linked pilot project was implanting “chips” into homeless people in Texas – he refers to an article that appears to misinterpret the word “biometric”.

(emphasis mine, read the article for more info)

The quantum dot thing is especially attractive to "mark-of-the-beast" folk because it seems like a "tattoo" (it would actually be invisible, except to infrared light, kind of like an invisible ink tattoo). Tattoo's have long been considered the likely form of the "mark", although microchips have been growing popularity over the last two decades. Quantum dots takes the best of both marks.

The ‘digital certificates’ Gates was referring to are human-implantable ‘QUANTUM-DOT TATTOOS’ that researchers at MIT and Rice University are working on as a way to hold vaccination records.

that's funny. fact check.com mentioned people not understanding what "digital certificates" were and thinking they were these implants , but I didn't really believe people were believing that sort of thing (aside from small populations and youtube channels that use bot type programs for views).

This (biohack website) theory has nothing to do with fundamentalists or the anti-Christ. just regular NWO type stuff.

In fairness the techno jargon can be easily misunderstood by the general public, and whether they "track" your movements through a microchip or through your phone is 6 of one... but a phone tracking system would be oodles cheaper. most importantly it seems conspiracy types are thinking the Quantum-dots would allowing movement tracking. but "tracking"/"tracing" mean different things to different sciences. I just realized Eleona said
means of tracking some people?

the MIT article is not about physical tracking, or even epidemiology vaccination tracking. All it "tracks" is what doses that one child standing in front of the nurse has received already in vaccines. They cant fly a helicopter over a village and see that "only 50% of kids have had their second mmr shot".

bold added for emphasis

The story cited Gates’ answer in the forum and then declared, “The ‘digital certificates’ Gates was referring to are human-implantable ‘QUANTUM-DOT TATTOOS.'”

But that’s not true. It’s a mash-up of two unrelated things.

First, digital certificates are used to send encrypted information over the internet, as in the common case of electronic signatures which are used to verify identity. They were officially defined by what is now called the Telecommunication Standardization Sector in 1988 and have always been virtual, not physical.

When Gates mentioned their use in the forum, he was referring to digital certificates as part of an effort to create a digital platform that would expand home-based, self-administered testing for COVID-19, the Gates Foundation said in an email to FactCheck.org.
He referred to the same effort to ramp up home testing at another point in the forum, saying, “The testing in the US is not organized yet. In the next few weeks I hope the Government fixes this by having a website you can go to to find out about home testing and kiosks… Whenever there is a positive test it should be seen to understand where the disease is and whether we need to strengthen the social distancing. South Korea did a great job on this including digital contact tracing.”

South Korea, which has implemented an extensive testing system, created a website that showed information about where patients who tested positive for COVID-19 had been in order to alert others in the area. Although the information on the site is anonymous, there has been some criticism that it’s an invasion of privacy.
Still, that’s a long way from “microchip implants.”


Kevin McHugh, a bioengineering professor at Rice University who worked on the study, told us by email that the ink couldn’t be used as a tracking device.

“These markings were developed to provide a vaccination record and there is no ability to track anyone’s movements,” McHugh said. “This technology is only able to provide very limited (e.g. non-personalized) data locally. These markings require direct line-of-sight imaging from a distance of less than 1 foot. Remote or continuous tracking is simply not possible for a variety of technical reasons.”

"Near-infrared quantum dots " sounds like some voodoo science encoding information at the quantum level, but it's simply fluorescent crystals - and specifically tiny crystals that glow in IR when exposed to IR light. They don't record information in the individual dots, it's just a pattern of a fairly small number of dots that can be used as something like a very simple QR code. Far less information than is stored in something like this:

It's just a (very quick to apply) simple tattoo

My apology, I had taken a screenshot of the post from a facebook group not noticing the comment right after it was cut off, it was mentioned that the covid19 vaccine could insert tracking that's why I posted it here.

You Can Now Tattoo A Child's Vaccination History in Invisible Ink
By Staff Reporter Dec 30, 2019 04:16 AM EST

As a response to the alarming trend of preventable deaths, researchers from the Massachusetts Institute of Technology proposed a unique solution to compiling individual medical histories. Using a method similar to tattooing a QR code, children could hypothetically be injected with an invisible dye that could store their medical data along with the vaccine itself.
Content from External Source
There are really two ways that "store their medical data" could work here, with a tattoo:
  1. Tattoo a unique identifying number on the person (a "digital ID") that you would then used to look up their records in a central database.
  2. Tattoo a mark on their skin for each vaccinee they get.
The second one seems to be the intent of the quantum-dot technology. You'd have a simple patch that would implant the mark when you get the tattoo. Ideally, the mark would contain the vaccine, as that would give you a 100% accurate record.

Importantly such marks (in #2) would NOT let you track the person in any way, they just tell you if they had a particular vaccine.

yes my post in comment #7 above explains that the alleged evidence being used is a forum Bill Gates was speaking at that was specifically about Covid-19.
but storing medical information below skin and physical tracking of Covid people are really 2 very different things. so writing a brief explanation about what your thread is actually about would be super helpful to readers.

In more depth:


Accurate medical recordkeeping is a major challenge in many low-resource settings where well-maintained centralized databases do not exist, contributing to 1.5 million vaccine-preventable deaths annually. Here, we present an approach to encode medical history on a patient using the spatial distribution of biocompatible, near-infrared quantum dots (NIR QDs) in the dermis. QDs are invisible to the naked eye yet detectable when exposed to NIR light. QDs with a copper indium selenide core and aluminum-doped zinc sulfide shell were tuned to emit in the NIR spectrum by controlling stoichiometry and shelling time. The formulation showing the greatest resistance to photobleaching after simulated sunlight exposure (5-year equivalence) through pigmented human skin was encapsulated in microparticles for use in vivo. In parallel, microneedle geometry was optimized in silico and validated ex vivo using porcine and synthetic human skin. QD-containing microparticles were then embedded in dissolvable microneedles and administered to rats with or without a vaccine. Longitudinal in vivo imaging using a smartphone adapted to detect NIR light demonstrated that microneedle-delivered QD patterns remained bright and could be accurately identified using a machine learning algorithm 9 months after application. In addition, codelivery with inactivated poliovirus vaccine produced neutralizing antibody titers above the threshold considered protective. These findings suggest that intradermal QDs can be used to reliably encode information and can be delivered with a vaccine, which may be particularly valuable in the developing world and open up new avenues for decentralized data storage and biosensing.

And from the paper, showing the relative sizes of things.

These QDs were 3.7 +/- 0.6 nm in diameter
QD encapsulation
After synthesis, a subset of S10C5H QDs was encapsulated in
poly(methyl methacrylate) (PMMA) microspheres using a spontaneous
emulsion/solvent evaporation technique (Fig. 2, A to D).
Emulsion parameters such as surfactant concentration and homogenization
speed were refined to produce particles that contained
60% QDs by mass with an average size of 15.7 ± 5.3 µm (Fig. 2E).
To verify in silico modeling data, we down-selected to three 3 x 3
arrays of microneedles: A 1500-µm cone (Fig. 3, A and B), a
750/750-µm cylinder/cone (Fig. 3, C and D), and a 1250/250-µm
cylinder/cone (Fig. 3, E and F) were printed using two-photon
polymerization to create a master mold in photoresist. These shapes
were maintained when the photoresist masters were used to produce
inverse polydimethylsiloxane (PDMS) molds and ultimately
positive dissolvable microneedles composed of poly(vinyl alcohol)
and sucrose (Fig. 3G).

I think a big part of the confusion come about in thinking that a "quantum dot" is one of the resultant dots on the skin
Metabunk 2020-04-19 17-10-32.jpg

But these are the remains of the dissolved needles, the glowing dots are about 0.25mm in size, 250µm, or 250,000nm. They are made up of microspheres that are 15µm, or 15,000 nm in size. Those microspheres are in turn made from "quantum dots" which are very small particles that are about 0.004µm, or 4nm in size
