Environmentally acceptable synthesis of nanoparticles for their potential use as textile coatings

Nanotechnology is a rapidly growing research area applicable in the textile industry, where nanoparticles integrated in the products can modify the existing materials or result with new product properties. Silver (Ag-) and gold nanoparticles (Au-NPs) are among the most commonly used NPs, and usually serve as coatings on medical textiles due to their antimicrobial properties. Therefore, there is an outgrowing need for the production of Ag- and Au-NPs, and it is necessary to develop a suitable and environmentally acceptable synthesis pathway. In this work, Ag- and Au-NPs syntheses were performed using glucose as a reductive agent. The influence of the different initial concentration of silver nitrate (AgNO3), tetrachloroauric acid (HAuCl4) and glucose was examined in a view of synthesizing the NPs of smallest size. The result has shown that the initial glucose concentration has a mild impact on both NPs synthesis while the influence of initial AgNO3 and HAuCl4 concentration was higher. Smallest Ag-NPs were synthesized using lowest glucose and highest AgNO3 concentration while the smallest Au- NPs were observed when both glucose and HAuCl4 were at the lowest or highest tested level.
