TOMSK, Dec 11 – RIA Tomsk. The preparation on nanosilver developed with participation of Tomsk Polytechnic University (TPU) scientists is effective in combating diseases of vanilla orchid and has low toxicity, TPU professor Alexey Pestryakov reported RIA Tomsk; results of the research published in Nanomaterials journal, now the medicine can be officially used on plantations.

"The Nanomaterials journal published the article with the results of our research, which prove that nanosilver-based drugs developed with the participation of TPU scientists effectively fight against diseases affecting vanilla orchid (the plant from which vanillin is made). And the most important thing – they have low toxicity", – the head of the TPU Research School of Chemistry & Applied Biomedical Sciences Pestryakov told.

He explained that modern drugs are often toxic: fighting against certain diseases, they give side effects that are often no less harmful than the main disease. In addition, viruses and bacteria quickly form resistant strains, and more and more "slaughter" compounds are needed to fight them. Nanosilver nanoparticle-based products solve both problems: silver is harmless to plants (at therapeutic doses), but is effective against pathogens – they cannot adapt to it.

"Large international group consisting of Russian (Tomsk and Novosibirsk) and Mexican parts (to which the Spaniards and British have joined) is working on drugs based on silver nanoparticles. Application range is very wide: from treatment of a syndrome of diabetic foot at people to fight against epidemics of a citrus, since nanometallic silver is universal and has a pronounced antibacterial and antiviral effect", – Pestryakov said.

According to the professor, crop production – is a separate powerful area in research into the practical use of "silver" products: they have successfully treated citrus fruits, sugar cane. The separate research group is working on the direction of vanilla orchids.

"This is quite expensive, but at the same time quite a capricious southern plant: the virus can easily destroy the entire plantation. Therefore, our drug will probably be in demand at farmers in Mexico and South America, where we are already well known. Now, after the publication of the research results, our development can officially be applied", – Pestryakov concluded.
