According to the report, the product, which is the result of efforts made at a knowledge-based company, has received approval from the Iran Nanotechnology Initiative Council (INIC).

Using silver nano-particles during the process of producing strings will make the particles entrapped within the strings, creating a long-lasting antibacterial property. Iranian researchers produced the antibacterial strings using silver ions and its combinations, which are deadly to a whole variety of bacteria. They have used nanotechnology to develop antibacterial polyester strings that cause the least degree of poisoning for human body.

Polyester is a kind of polymer with robust fabric, low water absorption property, and the least degree of shrinking when in contact with water compared to other types of industrial fabric. This material is widely used in the garment industry.

Polymer materials can be easily contaminated with bacteria or fungi, which could result in the transmission of diseases and serious infection.

An active antibacterial agent such as silver nano-particles can be used inside the structure of polymer materials to keep them from being infected by microbes. To that end, the new product was developed by local researchers.

Polyester strings made with the use of nanotechnology cause the least degree of poisoning for human body. The strings are made with silver nano-particles. Using different forms of silver is one common way of protection against bacteria.
