The experimental physicist and biomaterials researcher Prof. Antonietta Gatti examined various PCR test sticks under the microscope and analyzed their ingredients. The irritating result: they are made of hard materials and contain a large number of (nano)particles made of silver, aluminium, titanium, glass fibres, etc. – some of which are undeclared in the package leaflet. If these get into the mucous membrane, they can cause wounds and inflammation, according to the scientist. 2020News has learned from ENT doctors that they are increasingly detecting hardened mucous membranes in people who are frequently tested for SARS-CoV-2. Mucous membranes that are no longer intact can no longer fulfil their task of repelling viruses, bacteria and fungi before they reach the respiratory tract, as the pediatrician Eugen Janzen reports. The germs thus penetrate into the respiratory tract without any immune filter. Particularly problematic in this context: the warm humidity under the masks is the ideal breeding ground for germs of all kinds.

實驗物理學家和生物材料研究員 Antonietta Gatti 教授在顯微鏡下檢查了各種 PCR 測試棒並分析了它們的成分。令人惱火的結果是：它們由硬質材料製成，含有大量由銀、鋁、鈦、玻璃纖維等製成的（納米）顆粒——其中一些未在包裝說明書中聲明。據這位科學家說，如果這些物質進入粘膜，就會造成傷口和炎症。 2020News 從耳鼻喉科醫生那裡了解到，他們越來越多地檢測到經常接受 SARS-CoV-2 檢測的人的硬化粘膜。正如兒科醫生 Eugen Janzen 報告的那樣，不再完整的粘膜不再能在病毒、細菌和真菌到達呼吸道之前完成它們的排斥任務。因此，細菌無需任何免疫過濾器即可進入呼吸道。在這方面尤其成問題：口罩下溫暖的濕度是各種細菌的理想滋生地。

Gatti 教授在實驗室中分析了各種類型的拭子拭子，這些拭子拭子用於收集人體有機物以進行 PCR 診斷，使用電子顯微鏡（ESEM 和 EDS）檢查形態和化學成分。

生物逗號測試棒

對於來自中國深圳的 Biocomma 公司的“棉毛”棒，Gatti 教授無法確定它是由碳製成還是由棉花製成。產品中的污染物由碳酸鈣、不鏽鋼或硅酸鹽製成。

蝠鱝測試棒

一根來自中國蝠鱝的刷狀測試棒，有大量斷纖維。發現碳、氧、硅、鋯、硫、鋁、鈦和鈉是樣品的成分。

生物逗號測試棒 II

Biocomma 的另一個拭子似乎是由玻璃纖維製成的，或者至少是玻璃纖維塗層。成分是碳、氧、鋁、硅樹脂和鈦。不能排除附加塗層由有機材料組成。

尼龍 FLOQSwab®®

另一個測試棒——FLOQSwabs®——的塗抹器的尖端塗有垂直排列的短尼龍®纖維。 FLOQSwabs® 沒有用於包裹樣品的內核。

Gatti 教授寫道：“該公司解釋說，纖維芯由尼龍製成，並帶有一層專利材料塗層，在分析中證明是硅酸鋯鈦。這種塗層使纖維更硬，因此能夠撕裂粘膜。在塗片操作過程中施加的壓力可能會破壞一些留在原位的纖維。如果是這種情況，它們會引起異物反應，從而損害粘膜，導致呼吸和言論受到阻礙。”

拭子頸部的圖像

根據 Gatti 教授的分析，拭子頸部圖像上的小白點是銀納米顆粒：“銀是一種未在製造商數據表中聲明的材料。”

Gatti 教授得出以下結論：

“‘豪豬’拭子是由堅硬的纖維製成的。如果它們刮擦鼻粘膜，它們會損壞它，導致出血病變，或者在任何情況下都會對組織造成創傷。

在粘膜的癒合過程中，斷裂的纖維可以滲透到組織中而無法去除它們，從而導致肉芽腫或纖維化組織的形成，就像任何異物一樣。

檢查的醫療器械不完全生物相容，因此不符合 ISO 標準 10993 的要求和獲得 CE 標誌所需的測試。

總結：

一些拭子對鼻咽粘膜有危險。玻璃纖維又硬又脆，會劃傷粘膜並造成損傷。出血是測試侵入性的一種表現。

用塗片重複測試會引起慢性病變。脆性玻璃纖維碎片的釋放會引起生物反應，例如肉芽腫和/或組織纖維化。

這些塗片對嬰兒和兒童的健康構成威脅。根據 Gatti 教授的說法，如果需要進行測試，則必須對兒童進行小而溫和的塗片。

Prof. Gatti has analyzed in the laboratory various types of swab swabs used to collect human organic material for PCR diagnostics using electron microscopy (ESEM and EDS) to check morphology and chemical composition.

In the case of a "cotton wool" stick from the company Biocomma from Shenzhen, China, Prof. Gatti could not determine whether it was made of carbon or cotton. The contaminants in the product were made of calcium corbonate, stainless steel or silicates.

A brush-like test stick from manta, China, had a large number of broken fibers. Carbon, oxygen, silicone, zirconium, sulfur, aluminum, titanium and sodium were found to be components of the sample.

Another swab from Biocomma seemed to be made of glass fibers, or at least a glass fiber coating. Components were carbon, oxygen, aluminum, silicone and titanium. It could not be ruled out that an additional coating consisted of organic materials.

The tip of the applicator of another test stick – FLOQSwabs® – was coated with short nylon® fibers arranged vertically. FLOQSwabs® have no inner core to enclose the sample.

Prof. Gatti writes: "The company explains that the fiber core is made of nylon with a coating of a patented material that turns out to be silicate-zirconium titanium in the analysis. This coating makes the fiber harder, so it is able to tear the mucous membrane. There is a possibility that the pressure applied during the smear maneuvers may break some fibers that remain in situ. If this is the case, they can cause a foreign body reaction that can damage the mucous membrane in such a way that breathing and speech are hindered."

According to Prof. Gatti's analysis, the small white dots on the image of the swab neck are silver nanoparticles: "Silver is a material that is not declared in the manufacturer's data sheet."

Prof. Gatti comes to the following conclusions:

"The 'porcupine' swabs are made of hard fibres. If they scrape on the nasal mucosa, they can damage it, causing a bleeding lesion or, in any case, trauma to the tissues.

During the healing process of the mucous membrane, the broken fibers can penetrate into the tissue without any possibility of removing them, thus causing the formation of a granuloma or fibrotic tissue, as happens with any foreign body.

The medical devices examined are not fully biocompatible and therefore do not comply with the requirements of iso standard 10993 and the tests required to obtain the CE mark.

Summarized:

Some swabs present themselves as dangerous for the nasopharyngeal mucosa. The glassy fibers, hard and brittle, can scratch the mucous membrane and create lesions. The bleeding is an expression of the invasiveness of the test.
Repeated tests with smears can provoke chronic lesions. The release of fragments of the brittle glassy fibers can cause biological reactions such as granulomas and/or fibrosis of the tissue.
These smears pose a risk to the health of infants and children. If the tests are necessary, according to Prof. Gatti, small and mild smears must be carried out in children.
