Abstract

Silver nanoparticles in nanoparticulate system range in the size between 1-100nm. Silver nanoparticles synthesized from natural sources has a remarkable application in various fields of industry. Further, biological synthesis of Ag NPs from multiple herbal sources has been introduced to deal with certain drawbacks of physiochemical routes. The purpose of the foregoing review is to establish a biodegradable method to synthesize silver nano system using Trapa natans fruit. Trapa natans is a free floating aquatic plant grown in various parts of India, also commonly known as Singhara or water chestnut. The fruit consists of carbohydrates, flavonoids, starch, protein etc. In Indian Ayurvedic System of Medicine, Trapa natans has been recognized as a nutritive as well as cure to various diseases. The study also highlights the efficacy of kernels as antidiarrhoeal, appetizer, diuretic & tonic, in the treatment of STD, pregnancy. In this comprehensive review, green synthesis of Ag NPs of Trapa natans has also been covered and discussed for several other events like immunomodulatory, anti-bacterial, analgesic, anti-ulcer, anti-inflammatory.

Keywords: Silver nanoparticles, Trapa natans, pharmacological activity, nutritional aspects, application.
