“…It is applied in different fields such as chemistry, energy, textile, cosmetics, space research, information technology, biomedicine and agricultural. Recently various types of nanomaterials are widely used in biomedicine for drug discovery (Estelrich et al, 2015) and delivery (Ambwani et al, 2018), bio-imaging (Lobatto et al, 2012), tissue engineering and regenerative medicine (Jayakumar et al, 2011), proteomics (Patil et al, 2015), genomics (Basu et al, 2013), in vitro disease diagnosis (Mamaeva et al, 2018) along with treatment (Kamaly et al, 2016) as well as in stem cell research (Deb et al, 2012). In stem cell research, nanotechnology is applied in stem cell culture (Goto et al, 2007), expansion, differentiation and transplantation (Guo et al, 2017), nano delivery of DNA, RNAi and proteins in stem cells differentiation (Park et al, 2011) as well as in vivo delivery (Nguyen, 2013) and imaging of stem cells (Michalet et al, 2005).…”
