Using copper to fight the COVID 19 virus

The immunization campaign against the COVID 19 virus, which has been running worldwide for 3 months, has not been sufficient to heal the high number of patients, even with very intensive therapeutic support, because the viral load is too high.

What can we do to reduce this viral load?
The fact that copper can kill viruses and bacteria has been known since copper was processed in the Bronze Age. Recent studies have confirmed these effects. What can we do to reduce the viral load in the current pandemic and guarantee the survival of patients?

DOT has been involved in the development and production of antibacterial products for improved wound healing based on copper for more than 10 years. We are now examining the extent to which these products can be used against the burden of the COVID 19 virus and whether completely new possibilities should be exploited in this global situation. One such option is to use our 1, 2 and 5 cent coins made of copper-coated stainless steel. Everyone has these coins in his or her wallet or in a cookie jar at home. If one placed one of these coins into their mouth, antiviral and also antibacterial copper ions would be released from the copper coat into the surrounding saliva.

The COVID 19 viruses typically enter the lungs via the airways and destroy the lung tissue.  This must be prevented as long as the body has not developed a sufficient immune effect against these viruses.

It is initially sufficient to have one of these coins in the mouth for positively charged copper ions to accumulate in saliva and bind to negatively charged viruses that are already present or are about to arrive.  This weakens the viruses and kills them. If the viral load has already developed, more coins may be required to kill it. Only a few viruses are needed for immunization. Details of the procedure still have to be defined.

One should safely assume that the first immunization procedure will not work forever and must be repeated. Therefore, it is important for everyone to conduct the required oral hygiene as described above.

At the moment, the active ingredient does not need a disturbing host for it to be donated. Copper money, which is hardly used as a means of payment any more, is a solution that might ensure that this pandemic is globally controlled in a way that is affordable for everyone.

Let's get on with it now.

DOT - Working on customized solutions

We are driven to offer first-class solutions for medical implant coatings. Our R & D team is permanently working on improving existing coatings and developing trend-setting new coatings to help us achieve our goals.

DOT also develops and manufactures innovative regenerative products for the biomaterials market. We collaborate with well-known universities, scientific institutions and clinics in our research activities, and we are part of international research networks.

Our current research activities are focused on:

Antibacterial implant coatings

Approximately 500,000 hip joint prostheses are implanted worldwide every year. One of the most dangerous complications after implantation is implant-induced infection. We, therefore, understand the importance of developing implant surfaces that are able to prevent bacterial infection and stimulate cell growth simultaneously.

Copper has been commonly known to have an antibacterial effect if it is not bonded to proteins but is present as an ion. This is caused by the oligo-dynamic effect which can also be observed in silver. Copper has also been known to promote angiogenesis.

The project is dedicated to analyzing the antibacterial function of coatings on different implants containing copper and to investigating the various applications of the coatings in trauma and orthopedic surgery. The objective of this project is to investigate the application of the coatings in trauma and orthopedic surgery.
