Natural human enzyme can biodegrade graphene, scientists report

Degradation of pristine graphene occurs in the human body when interacting with a naturally occurring enzyme found in the lung, announced Graphene Flagship partners; the French National Centre for Scientific Research (CNRS), University of Strasbourg, Karolinska Institute and University of Castilla–La Mancha (UCLM).

Graphene-based products, including flexible biomedical electronic devices, are being designed for interface with the human body within the Graphene Flagship. If graphene is to be used for such biomedical applications, it should be biodegradable and thus be expelled from the body.

To test how graphene behaves within the body, Alberto Bianco and his team at Graphene Flagship partner CNRS conducted several tests to determine whether and how graphene was broken down with the addition of a common human enzyme. The enzyme, myeloperoxidase (MPO), is a peroxide enzyme released by neutrophils, cells found in the lungs that are responsible for the elimination of foreign bodies or bacteria that enter the body.

If a foreign body or bacteria is detected inside of the body, neutrophils surround it and secrete MPO, thereby destroying the threat. Previous work by Graphene Flagship partners found MPO to biodegrade graphene oxide. However the structure of non-functionalized graphene was thought to be more degradation resistant. To test this, Bianco and his team looked at the effects of MPO, ex vivo, on two graphene forms: single- and few-layer.

Bianco says, “We used two forms of graphene—single- and few-layer, prepared by two different methods in water. They were then taken and put in contact with myeloperoxidase in the presence of hydrogen peroxide. This peroxidase was able to degrade and oxidise them. This was not really expected, because we thought that non-functionalized graphene was more resistant than graphene oxide.

Rajendra Kurapati, first author on the study, from Graphene Flagship partner CNRS, said, “The results emphasize that highly dispersible graphene could be degraded in the body by the action of neutrophils. This would open the new avenue for developing graphene-based materials.

In-vivo testing is the next stage. Bengt Fadeel, professor at Graphene Flagship partner Karolinska Institute, says, “Understanding whether graphene is biodegradable or not is important for biomedical and other applications of this material. The fact that cells of the immune system are capable of handling graphene is very promising.

Prof. Maurizio Prato, leader of Work Package 4, said, “The enzymatic degradation of graphene is a very important topic, because in principle, graphene dispersed in the atmosphere could produce some harm. Instead, if there are microorganisms able to degrade graphene and related materials, the persistence of these materials in our environment will be strongly decreased. These types of studies are needed. What is also needed is to investigate the nature of degradation products. Once graphene is digested by enzymes, it could produce harmful derivatives. We need to know the structure of these derivatives and study their impact on health and environment.

Prof. Andrea C. Ferrari, Science and Technology Officer of the Graphene Flagship, and chair of its management panel, added, “The report of a successful avenue for graphene biodegradation is a very important step forward to ensure the safe use of this material in applications. The Graphene Flagship has put the investigation of the health and environment effects of graphene at the centre of its programme since the start. These results strengthen our innovation and technology roadmap.

    Yet we lose our right to refuse having this Contaminant in our body, when coerced/forced to:
    1) Wear face masks which are riddled with Graphene Oxide nanoworms which react to warm moist breath? https://brandnewtube.com/v/WtoyVD

    2) Have Fake “Tests” using Nasopharyngeal PCR Swabs, laced with Graphene Oxide.
    See the PDF from the Study in the Slovak Republic.
    Swabs for both PCR and LFT also being Sterilised by the known Carcinogen “Ethylene-Oxide Gas”, (“EO”).

    3) Have the Internationally Illegal COVID-19 “Vaccines”.

    And,
    4) rom the “Very Real” Chemtrails?

    “Neural Lace”, anyone?

    Personally, I do not consent and don’t want that Toxic crap anywhere near me and my Family, so any “Antidote” or way to Safely remove it, is very welcome 🙂

    If by any chance you are on the side of Humanity? You may want to hurry with this research as all the people in our Military, our Police, our Healthcare Systems and virtually Everyone, Everywhere else, is being Contaminated with this stuff Every Day and, when they are taken out of commission, who is there to Defend the Country from Invasion / Hostile Takeover? The Zombie Cowards, formerly known as “Men”?

    I have seen for myself, and Shared footage of, those Microscopic Graphene Oxide “Critters”, Wriggle and Squirm when breathed upon, under my microscope. It so reminds me of “Invasion of the Body Snatcher’s”.

      Those “critters” moving are results of magnetic function.

      For a clue, it’s why biochar, graphite, etc is so common in “filtering” things.

      So in the body, let’s say you have red blood cells near that. The iron would then likely be drawn to the graphene, clumping, collapsing/damaging the blood cells AND potentially making a larger magnetic sort of structure. That magnetic structure, composed of say a lot of iron oxides, happens to be like magnetite. Magnetite has EXCELLENT absorption in the 100mhz – 10ghz EM range. That range happens to be the vast majority of wireless EMF.

        If you did not know, IBM has magnetic iron oxide based storage that can for instance be used as an ID, for less than 200 atoms (they use 6 atoms per bit).

        That carbon nanotubes are also associated has something to do with cellular energy hijacking and transcievers.

            Btw, one of the features of their iron oxide storage stuff is that it’s only stable (at those low rates of atom usage) when it’s really cold.

            The thing is, when for instance, it gets to use more atoms, it can be stable at higher temperatures, like say body temperature.

            Where would something that initially require such cold temperatures be, before it’s injected into your body where it can “recruit” countless atoms?

            So really, don’t be too surprised if cancer rates increase significantly, thanks to those vaccines.

            Because among other diseases it causes, that’s one of the goals.

            I don’t mind saying this, but the fact that “people” like Fauci, Gates, Langer, etc are alive tells me MORE than enough about how pathetic people in modern societies are.

            They wouldn’t be alive, if I happened to be a “judge”.

            But anyway. I don’t have belief, trust, respect, hope for people, in general. They’re doomed. They’re in general too shit, and if they’re not too shit, too stupid.

            Is the picture becoming clear yet?

            IBM researchers use graphene to stimulate the body’s immune response
            IBM recently announced that its researchers have identified a new way to trigger the body’s immune response by using polymer-coated graphene sheets.
            https://www.graphene-info.com/ibm-researchers-use-graphene-stimulate-bodys-immune-response

            When they say “stimulate the immune response”, it means “expose it to toxic shit”, because that’s the only time the “immune system” responds.

            And again, you do not actually have an immune system. You have your bodily status, health. What is called the “immune system” is derived from that.

            They’re making you DISEASED PROGRAMMED BORG SLAVE RETARDS.

            No jokes.

            “In July 2014, IBM embarked on an ambitious project to find the next-generation chip technology to replace silicon, investing $3 billion over five years in this project and looking into graphene, carbon nanotubes, and more technologies.”

            They’re hijacking your bodies, firstly by demonizing it as a virus (with say, covid, though not only) and attacking it with specific sorts of mechanical means to enable you to be an “Internet of things” thing.

            And then, your body will be used as their hardware, for instance, for producing more toxic shit that they can sell as medicine to brainwashed programmed diseased zombiedronerobosheepclone borg retards.

            That’s pretty much the entirety of the situation.

    This seems to suggest that GO is biodegradable by MPO.

    BUT; the kicker is: NOBODY yet KNOWS what the biodegradation products ARE!

    So; HTF are pharmaceutical producers permitted to add GO into Vaccines under cover of “Trade Secret”; thereby not publishing the ingredient?

      It tends to be “encapsulated” and filtered out the body.

      Considering graphene oxide is carbon and oxygen, I wouldn’t be that worried about the results of how the body breaks it down (as it neutralizes things).

      Antioxidation capacity in general will aid removal of GO, as will mitochondrial/ATP function.
