Introduction: Nanotechnology is considered the sector of research and innovation that aims at building things, systems, devices, materials at a scale of atoms and molecules. Nanotechnology is an incredibly growing field in the era of modern science. Silver nanoparticles are known to have good pharmacological properties. Green synthesis of silver nanoparticles eliminates toxicity and is also without side effects. On the other hand Achyranthes aspera is an annual herb that belongs to the family of Amaranthaceae. Every part of the plant has medicinal values. Our study deals with the green synthesis of Achyranthes aspera mediated silver nano particles and assessment of their anti cariogenic and anti inflammatory properties. Aim: The current study aims at assessing the anti cariogenic and anti inflammatory properties of Achyranthes aspera mediated silver nano particles and investigating the efficacy of Achyranthes aspera mediated Silver nano particles. Materials and Methods: The methodology includes Green synthesis of Achyranthes aspera mediated Silver nano particle synthesis followed by tests for anti cariogenic and anti inflammatory properties. Results: Both the anti cariogenic and anti inflammatory activities of theAchyranthes aspera mediated silver nano particles had shown a proportionate increase in activity with the increase in µl concentration. Conclusion: Achyranthes aspera mediated silver nano particles have shown significant anti inflammatory and anti cariogenic activity and they are considered as potent anti inflammatory and anti cariogenic agents.
