Nasal COVID Swabs with Nanoparticles Cause Brain Damage!

Written by John O’Sullivan

In a follow up to our December article that PCR swabs may be contaminated with dangerous nanoparticles is this study from Trinity College, Dublin which affirms that nanoparticles alter DNA and cause brain damage.

The study appears in the popular journal, Nature. We urge readers to exercise extreme caution over nasal swabbing. The practice offers no added benefit, but does present higher risk of harm.

This compelling peer-reviewed study from the prestigious international science journal will add to concerns that PCR nasal swabs (nasopharyngeal swab) are unsafe, while other evidence shown below proves nasal swabs offer no extra value in COVID19 virus testing.

Key cause of concern is that the intrusive long swabs make contact with the delicate cellular barrier at the top of the nasal passage in close proximity to the brain. This is precisely the site which may be compromised by metal nanoparticles referred to in the Dublin study.

When these nanoparticles enter the brain their cellular messengers are released and may cause damage to the DNA of developing brain cells.

A write up on the study from Ireland by tells us:

“Nanoparticles are very small particles of between 1-100 nanometres in size. They are being increasingly used in drug delivery, chemotherapy, imaging and diagnostics due to their ability to travel within organisms by utilising cellular pathways. During their interactions with cell membranes and internalisation into cells, key signalling pathways and processes are altered. In addition to affecting the health of directly exposed cells, the internalisation of nanoparticles can also detrimentally affect neighbouring cells in a manner similar to the radiation-induced bystander effect.” [1]

We first drew wider attention to the possible insidious purpose to these nasal swabs -a completely unnecessary procedure when every law enforcement authority and doctor knows oral swabs are perfectly efficient at taking usable DNA samples- with our December article. [2]

Below is a diagram showing the ‘recommended’ way and the wrong way to take a nasal swab as published in a recent CDC document related to COVID testing [3]:

As the study from Ireland shows, this is very much a delicate safety issue with unintended consequence inherent with swabbing internally so close to the blood-brain barrier. The article continues:

“The scientists demonstrated that cells in the barriers, processed the nanoparticles by a natural cellular pathway, known as autophagy, leading to those cells generating signaling molecules. These signaling molecules caused DNA damage to the brain cells astrocytes and neurons; this was confirmed as when either autophagy or IL-6 (main cell messenger identified) was blocked, the amount of DNA damage was reduced. These findings support the idea that indirect effects of nanoparticles on cells which is the case in this study might be as important to consider as their direct effects when evaluating their safety.”

So-called ‘experts’ have falsely claimed the nasal swab poses no risk, as ludicrously claimed in this example ‘Can nose swab testing for COVID-19 be harmful?’ It claims:

“It is virtually impossible for swab testing to access or have any impact on the blood-brain barrier.”

The sham ‘expert’ in this criminally misleading web post attempts to fool readers into believing the nasal swab is ‘standard practice’ for obtaining ‘secretions’ but astutely avoids mention of the term ‘DNA’ because the authors know full well a standard oral swab is perfectly adequate in collecting ‘secretions’ which contain DNA, as anyone undergoing a police forensic mouth swab test can affirm.

But DNA testing is now commonly used to measure a person’s risk level for developing certain types of cancer, determine who someone’s father is, and to research a person’s family history. It can even be used on dogs to determine their breed and level of health.

Above, a graphic from

which tells what what you already suspected, there is no need to do a nasal swab to collect a DNA sample. The website tells us more about the very common procedure of testing your DNA:

How DNA Testing Is Done (The Process)

Because DNA is found in all of your cells, extraction is available in multiple forms.

Lab techs can use your saliva, blood, hair, and nails to test your DNA. However, at-home DNA test kits use a cheek swab or saliva collection to keep the process simple.

The part of the process that you experience is easy. All you have to do is submit a sample for testing. This is usually a sample of your saliva or blood.

However, because DNA is in all of your body’s cells, it can be extracted from your hair, nails, teeth, and skin too. But for the most part, saliva or blood samples are used because they are easier to extract the DNA from and have all the markers needed for the testing process.

But even those scientists specifically involved in detecting this elusive pandemic virus will tell you….

there is nothing uniquely useful about obtaining DNA via a nasal swab.

One recent peer-reviewed study performed during the pandemic, found that there is no benefit to nasal swabbing in low risk cases. [4]

Moreover, even the CDC recommends equally the use of oral and nasal swabbing [5] while other studies reported that SARS-CoV-2 detection was similar among oral fluid and nasal swab specimens when compared to nasopharyngeal swabs specimens. [6, 7]

But behind all this PCR testing nonsense remains the inescapable scientific fact that no swab – be it administered via the nose or the mouth – can be an effective tool in detecting a virus. We know this because there is ample data proving:

(a) the PCR test is merely a replication test; and

(b) no lab has yet isolated the SARS-COV-2 virus, the alleged cause of COVID19.

As the National Human Genome Research Institute tells us:

“Sometimes called “molecular photocopying,” the polymerase chain reaction (PCR) is a fast and inexpensive technique used to “amplify” – copy – small segments of DNA. Because significant amounts of a sample of DNA are necessary for molecular and genetic analyses, studies of isolated pieces of DNA are nearly impossible without PCR amplification.” [8]

In short, the PCR swabs are not fit for purpose, they do NOT detect infection by COVID19 and this renders the whole exercise of swab testing as pointless from a detection and clinical identification viewpoint. However, it may make perfect sense if the actual (hidden) purpose of the nasal swab was to insidiously infect and harm the patient with nanotechnological devices for personal tracking, uninformed vaccination and population control.

Even the iconic Anthony Fauci admits that the chances of getting accurate results from COVID PCR tests are ‘miniscule.’

This is not just a science farce, it is probably the biggest crime against humanity – likely to dwarf both world wars – if the eugenicist plan to cull 90 percent of us becomes apocalyptic reality.
