“…Nanomaterials have been investigated in the medical field for drugs (Cao et al, 2014; Ranganathan et al, 2012; Tan et al, 2011; Zhao et al, 2013) and genes carriers (Banizs et al, 2014; Eroglu et al, 2013; Liu et al, 2014), cancer therapy (Frank et al., 2014; Jabir et al., 2012; Marques et al, 2014; Wang et al, 2013), gene therapy (Rodriguez-Gascon et al, 2014), antibacterial agents (Amrol, 2007; Seil and Webster, 2012; Taylor and Webster, 2011), antiviral agents (du Toit et al, 2010; Mahajan et al, 2012; Parboosing et al, 2012), tissue engineering (Mazaheri et al., 2015; Partha and Conyers, 2009; Tautzenberger et al., 2012; Tonelli et al, 2012), medical diagnosis (Chen et al, 2013; Kang et al, 2015; Madani et al, 2013), medical imaging (Cao et al, 2014; Peng et al, 2008; Sheng et al, 2014; Yi et al, 2014), etc., which bring many benefits to humans. At the same time, studies on the biosafety of nanomaterials have been soaring in recent years (Vega-Villa et al, 2008).…”
