STUDY OF EFFECT OF SILVER NANOPARTICLES SYNTHESIZED USING EXTRACT FROM SIDERITIS SCARDICA, INCORPORATED INTO WATER-BASED AND UV COATINGS
In this work, we present an efficient and rapid green method for silver nanoparticles synthesis by using extract from Sideritis Scardica and direct sunlight irradiation. The synthesized nanoparticles were characterized by UV-Vis spectroscopy and Transmission Electron Microscopy (TEM). Then, the as obtained silver nanoparticles were mixed with water-based varnish, which is widely used for paperboard packaging in the food industry, pharmaceutical industry and others. Evaluation of the results of a microbiological study showed that water-based varnish with incorporated silver nanoparticles exhibited antibacterial activity against Escherichia coli K12 NBIMCC 407 bacteria and Bacillus subtilis NBIMCC 3562 bacteria. From the results obtained it is clear that these water-based and UV coatings with incorporated silver nanoparticles could find industrial applications in medicine and food industry as packaging with antibacterial properties.
