“…Similarly, metal and metalloid NPs were demonstrated for cancer therapeutics, diagnosis and antimicrobial applications (Sau and Rogach, 2010;Shakibaie et al, 2010;Sekhon, 2013). Particularly, superparamagnetic iron oxide and silver-silica composite NPs has widespread advantages for drug delivery, wound healing and anti-microbial applications (Veerapandian and Yun, 2013;Laurent et al, 2014). In this trend, integration of polymer species within the metal or metal oxide surfaces played critical role in enhancing the thermal stability, film forming capacity and hydrophobicity/hydrophilicity (Parveen and Sahoo, 2008;Karlsson et al, 2018).…”
