cze	Nanočástice ZnO v silikátových nátěrech	Byly připraveny a testovány silikátové fasádní nátěry založené na fotokatalytickém účinku nanočástic ZnO. Testování bylo prováděno dvěma metodami. Testovacími mikroorganismy byly Pseud. aeruginosa, Esch. coli, Staph. aureus a z plísní Asp. niger a Pen. chrysogenum.	Nanočástice, ZnO, silikátové nátěry
eng	NANOPARTICLES OF ZnO IN SILICATE COATINGS	Silicate facade paints based on photocatalytic active nano ZnO were formulated and evaluated. The photocatalytic efficiency of coatings was evaluated using two methods. An absorbance change of organic dye Orange II solution and a change of blue color coordinate of coatings dyed with methylene blue were measured. The agar plate method was used for evaluation of antimicrobial properties of coatings. The effectiveness of coatings was demonstrated using bacteria relevant to hygiene such as Pseud. aeruginosa, Esch. coli, Staph. aureus and fungi Asp. niger and Pen. chrysogenum. The silicate facade coatings containing nano ZnO showed excellent antimicrobial activity against bacteria. The coatings with nano ZnO only partially inhibited the growth of fungi.	nanoparticles, zinc oxide, silicate coatings,
