General information
- Short Summary
- Technology for obtaining antibacterial and antifungal compositions based on silver nanoparticles for the treatment of leather items such as gloves, shoes, leather insoles or sports items such as balls. Solutions based on silver nanoparticles can also be used to treat parchments and leather covers of documents to give them increased resistance against mold and bacterial attacks.
- Full Description
-
Improper storage conditions for leather items can lead to the development of bacteria, fungi or molds on their surface. In the case of certain objects, the simple use of them (shoes, bracelets, etc.) leads to the appearance of moisture in contact with sweaty skin and favors the development of microbial flora, a fact indicated by the specific smell these objects acquire and adverse effects on people's health. To remove the microbial flora, each person tries various methods, from simple washing (with the risk of irreversibly damaging the leather object), to dabbing with vinegar solutions, applying protective creams over the microbial flora, or dabbing with medicinal alcohol. None of these methods provide lasting antimicrobial protection and most of the time their application leads to a decrease in the lifespan of the object by damaging the skin.
At the moment, there is no solution directly accessible to consumers through which they can treat the various leather items they own, depending on their needs. There is also no method by which such different leather items as insoles, balls, bracelets or covers can be treated. The methods listed do not really provide protection, but are only palliatives to remove certain visible effects such as odor or cover the affected areas in the hope that they will not be noticed. None of the cleaning methods provide long-term protection of the protein support in the skin. To have a lasting antimicrobial effect, the agents providing the antifungal and antibacterial activity must remain in contact with the protein support of the skin. - Advantages and Innovations
-
The advantages of the proposed sanitizing solutions consist in the synergistic, complex activity of the antimicrobial agents, trigonal Ag nanoparticles, stabilized with biocompatible polymers glycerin and isopropyl alcohol, as well as in the fact that a long-lasting antibacterial and antifungal activity can be ensured after application. It is also very important that this solution allows the individual treatment of various leather objects, depending on the needs, objects that do not had such treatment applied at the time of their manufacture. The solution is also applicable to leather covers and parchments, helping to preserve them for a long time.
The Ag nanoparticles stabilized with biocompatible PVP or PEG polymers will adhere to the protein fibers and will remain stuck both on the surface of the object and deeper in the skin structure and will ensure a long-lasting antibacterial and antifungal activity. Adhesion of the nanoparticles will also be achieved through the development of Ag-S covalent bonds through the -SH groups in the proteins. Under these conditions, the chemical binding of Ag nanoparticles will ensure a prolonged antimicrobial activity and, moreover, the release of Ag ions or nanoparticles into the environment will be lower, so the negative implications on the environment will be reduced. - Stage of Development
