Fact Check: quantum dot dye technology does not feature microchips

Correction Jan 6, 2022: An earlier version of this check stated that there were no plans to use microchip implants during the coronavirus outbreak. This statement has been removed and the headline revised after a Swedish company in December 2021 announced the launch of implantable microchips holding COVID-19 vaccination details. The verdict of the check remains unchanged, as the claim examined in the original fact check incorrectly suggested that Bill Gates would use ‘quantum dye technology’ to implant a microchip with vaccination records. This dye technology does not use a microchip.

A viral claim on social media says Bill Gates is planning to use microchip implants to fight the coronavirus. Most of the posts say Gates will “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 claim has been shared at least 1,000 times on Facebook (here, , here) and at least 3,600 times on Twitter, as of March 27, 2020 (here , here , here).

Most of the iterations of this claim link to or take their information from a post on March 19 (here).

The story, titled “Bill Gates will use microchip implants to fight coronavirus,” includes an authentic quote from a Q&A with Reddit about COVID-19 (here). But the story then uses his “Ask Me Anything” answer as a springboard for speculation and unattributed conclusions. They were not supported by Gates’ responses in the interview.

Written like a news article, the post misleadingly says that “quantum dot dye,” a technology indeed founded by the Gates Foundation, would be used as “human-implantable capsules that have ‘digital certificates’ which can show who has been tested for the coronavirus” (here).

Kevin McHugh, one of the lead authors of the “quantum dot dye” research paper, said, “The quantum dot dye technology is not a microchip or human-implantable capsule and to my knowledge there are no plans to use this for coronavirus.”

Gates did mention the possibility of having a “digital certificate” for health records “eventually,” but he did not say these certificates would be “microchip implants.” This was the Reddit exchange:

“Q: What changes are we going to have to make to how businesses operate to maintain our economy while providing social distancing?

Bill Gates: The question of which businesses should keep going is tricky. Certainly, food supply and the health system. We still need water, electricity and the internet. Supply chains for critical things need to be maintained. Countries are still figuring out what to keep running. Eventually we will have some digital certificates to show who has recovered or been tested recently or when we have a vaccine who has received it.”

When asked about the claim, the Bill and Melinda Gates Foundation told Reuters, “The reference to ‘digital certificates’ relates to efforts to create an open source digital platform with the goal of expanding access to safe, home-based testing.”

IBM describes a digital certificate as an “electronic document” used to identify an individual, and associate the identity with a public key. Like a driver’s license or a passport, it provides proof of a person’s identity (here).

Bill Gates has been repeatedly mentioned in other false claims regarding the coronavirus outbreak. A recent Reuters fact-check debunking a false claim about Gates can be seen here .


False: Bill Gates foresees the use of “digital certificates” with health records, but did not say in March 2020 that these would be in the form of microchip implants.
