Abstract
The biological synthesis of nanoparticles using plant extracts plays an important role in the field of nanotechnology. In this study, rapid, simple approach was applied for synthesis of silver nanoparticles using , Clerodendrum infortunatum, Mucuna interrupta, Phlogancanthus thyrsiflorus and Sansevieria trifasciata aqueous leaf extract. The plant extract acts both as reducing agent as well as capping agent. To identify the compounds responsible for reduction of silver ions, the functional groups present in plant extract were investigated by FTIR. Various techniques used to characterize synthesized nanoparticles are Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM) and UV–Visible spectrophotometer. Results confirmed that this protocol was simple, rapid, one step, eco-friendly, non-toxic and might be an alternative conventional physical/chemical methods. Conversion of silver nanoparticles takes place at room temperature without the involvement of any hazardous chemicals.
Highlights
Nanotechnology is the science of materials which have at least one dimension in the range of 1-100 nm
The use of plant extract for the synthesis of nanoparticles it proves to be environment friendly and cost effective as compared to the physical or chemical procedures which are hazardous for the environment (Sant et al, 2013)
There are several literature related to the synthesis of silver nanoparticle using plant extract, fungi, bacteria (Sastry et al, 1998; Sathishkuma et al, 2009; Dwivedi and Gopal, 2010; Philip, 2010; Kaviya, 2011; Ghosh et al, 2012)
Summary
Nanotechnology is the science of materials which have at least one dimension in the range of 1-100 nm. Nanotechnology provides the facility to engineer the properties of materials by controlling their size, and this has conducted researches toward a multitude of potential uses for nanomaterials (Benjamin and Bharathwaj, 2011). Metallic nanoparticles exhibit unusual optical, thermal, chemical, and physical properties (Bains, 1993). Several techniques including chemical and physical method are developed to synthesise metallic nanoparticles. Recently a resurgent developed for the green synthesis of several nanoparticles through biological mean (Thuesombat et al, 2014). The use of plant extract for the synthesis of nanoparticles it proves to be environment friendly and cost effective as compared to the physical or chemical procedures which are hazardous for the environment (Sant et al, 2013). There are several literature related to the synthesis of silver nanoparticle using plant extract, fungi, bacteria (Sastry et al, 1998; Sathishkuma et al, 2009; Dwivedi and Gopal, 2010; Philip, 2010; Kaviya, 2011; Ghosh et al, 2012)
