Novosibirsk scientists have proposed a new way to test for COVID 19, based on the existing Russian technology "Health Monitor" BioSilver Lab. A non intrusive test to analyse bio markers contained inside our breath and detect patterns from people infected. With the support of machine learning and artificial intelligence technics, Health Monitor is currently the most advanced technology for this type of use case.

Novosibirsk scientists have proposed a new way to test for coronavirus based on the existing Russian technology "Health Monitor" BioSilver Lab.

The human exhalation is a complex mixture of about 750 volatile compounds, the so-called “imprint of metabolism”. Analysis of human breathing allows non-invasive monitoring of biochemical processes, which makes the procedure accessible and safe, the SB RAS press service said.

There are facilities in the world that can conduct an accurate analysis, but they are expensive and are used in special laboratories. In Novosibirsk, a convenient domestic analyzer was developed for widespread use.

Novosibirsk scientists have proposed a new way to test for coronavirus based on the existing technology for analysing human expiration.

At the Institute of Automation and Electrometry of the SB RAS, together with an industrial partner, the company Biosilver Lab/Scientificcoin a domestic gas analyzer HEALTHMONITOR was created, which allows overcoming the existing technological barrier for the transfer of the method to mass use, the scientists explained.

The device is already manufactured and used in 12 countries, including the USA, Germany, Italy, India, China, Belgium and others. Now scientists are planning to tune it to determine the coronavirus.

According to the Russian Fund for Basic Research, a similar material based on spunbond and nanosilver was developed by colleagues at the Institute of Solid Body Chemistry and Mechanochemistry of the Siberian Department of the Academy of Sciences from Russia.

Scientists hope a material which they say can kill bacteria and viruses could be used in face masks to help tackle the outbreak of the new coronavirus, which has killed over 1,000 people.

The material features nanosilver, which has antibacterial properties, and was made using a process known as melt blowing. This makes polypropylene microfibers with a diameter of one micron, explained Alexander Zhanovich Medvedev, who worked on the project and leads a lab at the Siberian Branch of the Russian Academy of Sciences (SBRAS). It is not clear if the research had been published in a peer-reviewed journal.

Medvedev said in a statement that he and colleagues fitted their creation in the inner layer of a conventional three-layer medical mask.

Researchers tested the mask against the influenza A virus as well as the staphylococcus and E. coli bacteria, according to Nikolai Zakharovich Lyakhov, chief researcher at the Institute of Chemistry and Technology at the SBRAS.

When the team compared the new material with that of regular masks, ten thousand times more viruses passed through the latter.

Lyakhov said: "Our material kills, completely deactivates viruses." However, he added it's unclear exactly how it works, and this problem must be approached in separate research projects.

The team believe the material could protect people against influenza A for up to 10 hours, compared to regular masks which need to be changed every one to two hours.

According to the Russian Foundation for Basic Research, similar material based on the deposit of active ions would also have been developed by colleagues from the Institute of Chemistry of the Solid State and Maccanochemistry of the Siberian Branch of the Russian Academy of Sciences.

Covid-19: 1.4 million masks per day produced by fashion companies in Italy.

Tests have shown that on the material obtained, by applying the nano silver on the fabric of the masks with the technique called 'Melt blowing' (a method of manufacturing micro and nanofibers in which a polymeric melt is extruded through small nozzles surrounded by blowing gas at high speed) the virus is killed instantly and, with prolonged contact, effectiveness even increases. The main advantage, however, remains another - the mask is in fact capable of self-cleaning, without losing its effectiveness for several days. On the other hand, the cost of the masks will be slightly higher, but definitely lower than the cost of a continuous replacement.

Russian scientists have created a unique material for medical masks, which has high antibacterial activity.

The innovation was developed by specialists from the Institute of Solid State Chemistry and Mechanochemistry of the SB RAS of the Russian Federation. The innovation has already passed tests, during which masks created from such material showed quite good results.

The fact is that silver-treated Spunbond almost instantly kills the virus. With prolonged contact, its effectiveness even increases. It is worth recalling that cotton-gauze medical dressings must be changed every 1.5-2 hours.

But in the case of the mask presented by scientists of the Institute of Chemical and Chemical Engineering, the efficiency of use reaches 10 hours under the conditions of continuous exposure to a pathogenic environment.

Moreover, scientists claim that the new mask is able to self-clean. In other words, using it during the day, the mask can be removed at night and the next day put on clean again.

The first studies of such material were conducted in October 2018. Experts concluded that living microorganisms simply cannot penetrate masks with such a composition. The mask was first tested on influenza A virus, on staphylococcus and E. coli (Escherichia coli - E. Coli).

While tests of the mask from the new material against coronavirus have not yet been conducted. Infectious disease doctors believe that if the influenza A virus was destroyed by this material, then, most likely, other viruses that cause respiratory infections should also suffer the same fate.

At the same time, manufacturers of medical masks report a shortage of this remedy as a result of increased demand amid the spreading coronavirus.

The manufacturer does not report on whether it is planned to test masks against coronavirus in the near future and whether antimicrobial masks can be expected.

Diabetic foot ulcers are one of the major complications of patients with diabetes mellitus. And due to their high susceptibility to microbial infections, are the leading cause of hospitalization and amputation of lower limbs. It has been well studied the antimicrobial properties of silver nanoparticles (AgNPs), therefore their use in biomedicine is a trend.

Herein we present for the first time the use of AgNPs for the treatment of diabetic foot ulcers of grade II and III of Wagner classification. Ulcers were treated by topical administration of AgNPs (at 1.8 mg/mL of metallic silver) in addition to conventional antibiotics. In all the cases presented in this study, a significant improvement in the evolution of ulcers was observed upon AgNPs administration. The edges of the lesion reached the point of closure. These results constituted the basis for further studies on the use of AgNPs for the treatment of chronic ulcers from different origins.

According to our knowledge in this study we present for the first time a successful treatment of diabetic foot ulcers of Wagner classification degrees II and III with AgNPs administered topically into the wound. Daily topical administration of AgNPs solution with metallic silver concentration of 1.8 mg/ml causes an improvement of the wound healing in average in less than 25 days of treatment.

Ethical approval to report this case series was obtained from Instituto de Servicios de SaludPública del Estado de Baja California, Sección Hospital General de Tijuana (No. 000056 Septiembre de 2011). Also, written informed consent was obtained from the patients for their anonymized information to be published in this article.
