Sažetak
Silica-Nigella sativa L. hybrid materials were prepared and characterized as a potential new material for plasters and wound dressings. Nigella sativa L. commonly known as black cumin are used extensively for flavouring and medicinal purposes. The oil and the seed constituents have shown anti- inflammatory effects on several inflammation-based models including experimental encephalomyelitis, colitis and arthritis through suppression of the inflammatory mediators prostaglandins and leukotriens. All mentioned activities are necessary for antibacterial coatings and are very important for e.g. chronical wounds. In textile technology sol-gel process offers great opportunities by creating new surface properties, especially in this case where nanosol contains plant essential oil. Target of this paper was to prepare a coating with black cumin essential oil by sol-gel process with 3- glycidoxypropiltrimethoxysilane (GLYMO) and without GLYMO. Coatings were applied by dip- coating on the cotton and polyamide. It was concluded that the retention of textile character as an important requirement of new textile materials was successfully met. Absorbency of Textiles, pH of the Water Extract and measuring of the angle of recovery was carried out. The coatings were characterized by infrared spectroscopy (FITR-ATR) and agar diffusion plate test (antibacterial activity) by determining bacterial reduction of Escherichia coli and Staphylococcus aureus. Based on obtained results it can be concluded that good antibacterial effect show all treatments on fabrics.
