Nanobiotechnology Driving In Roads for the Treatment of Viruses Including COVID-19

The introduction of Nanotechnology has truly been one of the biggest game-changers of this past decade.  Nanotechnology is “the understanding and control of matter at the nanoscale, at dimensions between approximately 1 and 100 nanometers, where unique phenomena enable novel applications. Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at this length scale.  Matter such as gases, liquids, and solids can exhibit unusual physical, chemical, and biological properties at the nanoscale, differing in important ways from the properties of bulk materials and single atoms or molecules.”

Nanotechnology holds great promise in offering innovative solutions for the prevention, diagnosis and treatment of a wide range of health issues and viruses, including COVID-19. Graphene, nanodiamond, polymer nanofibers (e.g., polyacrylonitrile), and such nanoparticles as silver, titanium dioxide, and copper oxide are common elements leveraged in the various nanotechnology products available today.

Products That Use Nanotechnology To Battle Viruses, Including COVID-19:to fight against coronavirus:

1.  Respiratory Masks:

Face (or Respiratory) masks are used to filter out up to 95 percent of fine pollutants that are at  300 nm in diameter or more.  These types of masks are commonly calledN95 masks.  Nanofiber membranes are made of a dense spiderweb-like network of nanofibers, providing high surface area. These membranes are incorporated into N95 mask to provide high breathability and filtration efficiency thanks to their strong and durable structure.

YAMASHIN-FILTER CORP.  Many of the commonly used disposable masks on the market today trap dust and viruses by static electricity. Due to the high moisture absorption from exhaled breath and extended use, the collection performance of those masks greatly reduces over time.  YAMASHIN Nano Filter™, manufactures the world ‘s first nanofiber mask inner sheets using in-house developed nanofibers made from synthetic polymers. This mask has a 3D structure made of extremely thin nanofibers with high trapping properties.

Copper3D produces a face mask, NanoHack, which incorporates a novel modular filtration system manufactured with the innovative nanocomposites of PLACTIVE® and MDflex®. This active filtration system includes three layers of a non-woven polypropylene impregnated with 5% copper oxide nanoparticles that deliver high antimicrobial, antiviral, and antibacterial properties.

2.  Air Filtration Systems:

Mack Antonoff HVAC brings to market clean air filtration systems for the mitigation of COVID-19 (Coronavirus), mold, mildew, and pet dander. The 5” Hepa, Peco, and Nano filters with UV light are installed into your existing ductwork.  These air filters have become essential for families with allergies, asthma, bronchitis, and other health issues.  These are filters also plus keep your home smelling fresh!

Turn-Key Environmental Consultants sells HealthPro® Compact Air Purifiers, which capture 99.5 % of particles (e.g., viruses and bacteria) down to 0.003 microns. At the heart of this revolutionary system is the exclusive IQAir HyperHEPA® filtration technology. A dense network of nanofibers effectively traps particles of all sizes.

3. Disinfectants:

Nanoveu antiviral screen protectors covering both the front glass and cover of a phone utilizes copper oxide nanoparticles as the active antiviral material and offers a non-invasive and unobtrusive way of protecting a user from a range of microbes (such as E-coli, influenza, MRSA, and coronavirus). This product, or nano shield, kills 99.99% of viruses and bacteria in minutes. The high surface area of copper oxide nano-particles generates more reactive oxygen specie molecules than copper metal which rupture cell walls and protein structures of bacteria and viruses causing eventual death. The coating was tested against Japanese JIS Z 2801/ISO 22196 standards and is undergoing further testing in independent labs against globally recognized human coronavirus surrogate OC43 and mouse coronavirus which comes from the same family as SARS-CoV-2.

4.  Optical Biosensor Nanotechnology:

Optical biosensor nanotechnology is a new tool for testing and detecting COVID-19.  The test results are delivered within 30 minutes and come directly from the patients’ samples requiring no centralized laboratory tests. This new technology easily determines whether a patient is infected with the coronavirus or the influenza virus.. This new biosensor tool is also to be used to analyze various forms of coronavirus present in reservoir animals, such as bats, to detect and track the potential evolution of these viruses and prevent future outbreaks in humans.

CONVAT is a current provider of optical biosensor testing for the immediate diagnosis of COVID-19.

5.  Medical Supplies:

“Silver has been used for the treatment of medical ailments for over 100 years due to its natural antibacterial and antifungal properties. The nano silver particles typically measure 25nm. They have extremely large relatively surface area, increasing their contact with bacteria or fungi, and vastly improving its bactericidal and fungicidal effectiveness.”“Nano silver when in contact with bacteria and fungus will adversely affect cellular metabolism and inhibit cell growth. The nano silver suppresses respiration, basal metabolism of electron transfer system, and transport of substrate in the microbial cell membrane. The nano silver inhibits multiplication and growth of those bacteria and fungi which cause infection, odor, itchiness and sores.” Source:  https://www.nanosilver.com.my/nano-tech-facts/what-is-nano-silver/A variety of medical supplies are produced based on nano silver technology.  Such supplies include but not limited to scrubs, gloves, wipes, aprons, bandages, draw sheets, bed pads, and toilet papers. The superb antimicrobial, antibacterial, and antiviral properties of silver nanoparticles are exploited in these products distributed by many leading medical supply companies such as Vileda, Dirk Rossmann GmbH, Walgreen Co, ALEVA, Arco Limited, Key Surgical, Mapa Spontex UK Ltd, Alpha Consumables Ltd, Ansell, Code Happy, Heart Soul Scrubs, Cherokee Uniforms, NMI Health, and Khorasan Paper Industries.
