Silver has been in use since ancient times in the form of metallic silver, and silver nitrate, and silver sulfadiazine for the treatment of burns, wounds and several bacterial infections. Silver and its compounds are known as effective antimicrobial agents (Jung et al., 2008 and Rai et al., 2009). In recent years, there has been substantial interest in the application of silver nanoparticles (AgNPs) in various fields. AgNPs have been applied in intercalation materials for electrical batteries, optical sensors, catalysts in chemical reactions, biosensors and bioactive materials, medical and pharmaceutical nanoengineering for delivery of therapeutic agents and for antimicrobial agents (Balan et al., 2007, Luo et al., 2006, Qureshi et al., 2011, Rybak et al., 2010, Thanh and Green, 2010 and Tolaymat et al., 2010). The main interest related to innovative products based on silver nanoparticles P276-00 concentrated on the management of diseases related to skin/wound infections (Ili? et al., 2009, Paladini et al., 2014 and Silva et al., 2014) and the design of antimicrobial agents and drug delivery vehicles (Kim et al., 2007, Ge et al., 2014, Narayanan and Park, 2014, Ramage et al., 2014 and Kumar and Poornachandra, 2015). AgNP as a metal possesses unique physicochemical characteristics, including a high ratio of surface area to mass, sizes in the range of nanometres (10− 9 m), high electrical and thermal conductivity, chemical stability, catalytic activity and nonlinear optical behaviour (Balan et al., 2007 and Tran et al., 2013). Heavy metals including silver, even in small concentrations can induce structural and functional changes and, thereby destroy the cell of a microorganism. At relatively high concentrations, heavy metals act as a general protoplasmic poison, inducing denaturation of proteins and nucleic acid. The antibacterial effect and possible mechanisms of AgNP actions involved in the deactivation of bacterial strains are known, often mistakenly interpreted as a basis for antifungal activity (Choi et al., 2008, Martínez-Casta?ón et al., 2008, Rai et al., 2009 and Xiu et al., 2011). However, little is known regarding the effects and mechanisms of their antifungal activity. It is most likely that, the size of the particle enhances its antimicrobial activity. Nanoparticles have a high surface to volume ratio which changes their properties when compared to non-nanoscale forms of the same material. Moreover, nanoparticles are able to penetrate biological membranes and cell walls more effectively, leading to cell death (Marambio-Jones and Hoek, 2010 and Xiu et al., 2011). The aggregation of nanoparticles drastically decreases their accessibility, resulting in insufficient functionality against microorganisms (Badawy et al., 2010 and Badawy et al., 2012). For this reason, homogeneous distribution of nanoparticles over building materials is required to guarantee better contact and reaction with microorganisms.
