Nanotechnology is a collection of knowledge and advanced techniques that allow the production of substances and structures at the nanoscale. This means that each product produced has at least one dimension (in simplified terms – length, height or width) with a value not exceeding 100 nm (nanometers). If the obtained structure has three dimensions in the nano scale, then we deal eg with nanoscale spheres (eg fullerene). When two of them are on the nano scale, the product is a nanowire, nanofiber, a nanotube or another analogue product (eg a carbon nanotube). When only one dimension is on the nano scale, we deal with a nanolayer (eg graphene flake). For comparison – the influenza virus has a size of 80-120 nm, while the staphylococcus aureus (bacterium) reaches up to 1000 nm. How does a human cells look like in this comparision? Homan cell reach 6000 nm, and are only a part of a larger structure.
Nanoscale is a microscopic world where we measure every dimension in nanometers. The nanometer is a billionth of a meter. One nanometer is 1: 1,000,000,000 part of meter. A good view of the nanoscale gives the following scheme:
Basically, there are two methods of synthesis of nanocompounds: the “top down” method involving the decreasing size of “large-scale” substances, eg by grinding and the “bottom up” method, that combine the smallest “bricks” (atoms), with each other to obtain the desired size and shape of the molecule . We use the “bottom up” method because it gives us better control over the effect, although it requires more work and diligence from us.
Due to their small size and unique properties, nanocomponents are ideally suited for the functionalisation of finished products. Thanks to them, we can create a trash bin that kills a bacteria, a self-cleaning sink or a jacket that warms us to the required temperature. The possibilities of their use are limited only by our imagination!
Yes, we have our own synthesis technologies for nanoproducts that have been developed by our team. Production take place in our laboratories, as well as work on the implementation of nanoparticles for finished products. Thanks to this, we can constantly develop new solutionas and we are not technologically limited. We can freely modify our products to meet the requirements of our clients.
Nanoparticles are all nano-scale structures that have at least one dimension in this scale (nanolayers, nanowires, nanospheres, etc.). Nano compounds are chemical compounds on the nano scale. This means that silver or copper at the nano scale are not nanocompounds, because they do not bonded with other atoms, while nanocopper oxide is a nanocompound, because it consists of combined atoms of copper with oxygen. Nanometals are pure metal nanoparticles. The safest is using of the term “nanoparticle” e.g. “silver nanoparticle” or “zinc oxide nanoparticle” because it covers the widest group of substances. Often, prefixes such as “nanotube”, “nanosphere”, “nanopyramide” or other of this kind appear and they determine the specific shape of the molecule.
Reducing the scale of substances to “nano” allows you to change their chemical and physical properties. The insulator can be changed into a electricity conductor, a colorless substance can get sparkling colors and soft can be modified to ultra-hard. In addition, when changing to the “nano” scale, even such basic properties as the melting point or chemical reactions in which the substance participates change. That’s why nanotechnology allows you to change silver into an effective UV protection filter, soft graphite in carbon nanotubes that increase the hardness of plastic and copper into an effective killer of bacteria and mold.
Despite the fact that the cost of nanoparticles is relatively expensive (cost per kilogram), the final cost of their implementation is financially attractive. Why? Because nanoparticles exhibit their propertiesat low concentrations, which in many cases can be called trace. For example, to give biostatic properties to plastic, 10 ppm of nanosilver per kilogram of plastic is enough. What does it mean? That in a kilogram of plastic there is 0.01 g of nanosilver which is 0.001% of the total weight!
Nanotechnology is a relatively new and dynamically expanding science. Substances such as nanosilver differ in their properties from substances on the macro scale (ie nanosilver has different properties than silver eg found in jewelry). What’s more, nanosilver changes its properties with the: size, shape of molecules, presence of auxiliary substances, etc. It gives a gigantic amount of different substances which testing is difficult. Our company has experience in working with nanoparticles and we offer our clients only safe solutions that have been tested by us. Therefore, no one should be afraid of nanotechnology from proven sources. Nevertheless many people are impersonating “nano” by offering substances of unknown origin, spoiling the image of this technology of the future!
We can distinguish three types of enterprises operating with the use of “nanotechnology”: manufacturers of nanoparticles, companies that use nanoparticles and companies that mediate nanoparticles trading. By far the least is the producers, which include ITP-System. The unprecedented properties of nanoparticles make growing interests of using nanoparticles in various goods production.
Both in Poland and in the World there is a growing interest in nanotechnology, but there are limited amount of companies with their own knowledge and technologies to produce nanoparticles, which is why we encourage you to cooperate with our company. It is very difficult to find another, equally experienced company that has the competence to implement nanotechnology, which makes us proud and allows us to constantly work on the expand our offer.
There are also many companies that impersonate to nanotechnology, but in true have nothing to do with nanotechnology. This is particularly evident from the perspective of the nanosilver market, where are many distributors of the so-called “silver water”, “nanocolloids” and other products that are not in any way related to nanotechnology and are using limited knowledge of customers.
To successfully implement nanotechnology, focus on several important topics. First, you should ask the manufacturer of nanoproducts to determine the best additive (or additives) that will allow you to achieve the desired effect. Often, the determination of the composition and concentration requires additional research and requires the involvement of both parties in the research process. It also requires transferring part of the knowledge about the target product to the supplier of nanotechnology. The second important parameter is uniform distribution of nanoadditive inside target product. Inaccurate mixing or combination of raw materials with a nanoadditive can result in the opposite effect. Thirdly, the final product should be tested for the desired properties (not the raw material). Often, customers ask us for the results of, for example, bactericidal silver, which can radically change after its mixing with f.ex. paint. Therefore, we perform tests on a ready-made, modified product.
