Abstract
In Indian pharmacopoeia, a number of Swertia plants are used as crude drugs. Plants are readily available and can be used to manufacture metal nanoparticles, especially AgNPs. Plants convert metal ions to metal nanoparticles at a far faster rate than microorganisms. Plant-based nanoparticle synthesis is also superior to microorganism-based nanoparticle synthesis in terms of biosafety. Nanoparticles made from plant extracts are cost-effective, provide healthy work environments and societies, protect human health and the environment, and result in less waste and safer goods. They have unique properties that aid in molecular diagnostics, therapies, and devices which can be used in a variety of medical procedures. The physical and chemical methods are the most commonly used for the synthesis of silver nanoparticles. For morphological studies of nanoparticles, microscopic techniques such as scanning electron microscopy, transmission electron microscopy, and atomic force microscopy are commonly used. FTIR spectroscopy, on the other hand, is a chemical analytical technique that measures infrared intensity versus light wavelength (wavenumber). Antibacterial activity is one of the most important applications for such nanoparticles (Kumar et al. 2012b; Khan et al. 2015). The medicinal plant Swertia chirata has been researched for its ability to synthesize poly shaped gold nanoparticles (Au NP). Au NPs have been linked to significant scientific contributions as a result of their use in a variety of fields, including cosmetics, bio molecular imaging, cancer treatment, and drug delivery. Crop defense and agriculture are two areas where nanoparticles are being used. Antimicrobial silver nanoparticles are already widely used in commercial medical and consumer products. By various methods Nanoparticles synthesized have been used in diverse in vitro diagnostic applications silver, silica, and platinum nanoparticles. Leaf extracts to aqueous silver nitrate solution, the color of the solution changed from faint light to yellowish brown and finally to colloidal brown indicating formation of silver nanoparticles. The process is simple and can be done at room temperature, making it a feasible and environmentally friendly way to make benign nanoparticles without a lot of energy or waste. Nanomaterials have different types such as copper, zinc, titanium, gold.
