Synthesis and Characterization of Platinum Nanoparticles (Pt-NPs) from Centella Asiatica L Leaf Extract

Abstract

Nanotechnology is a burgeoning field and is widely applied to biomedical engineering and nanomedicine. Platinum nanoparticles (Pt-NPs) are noteworthy scientific tools that are being explored in various biotechnological, nanomedicinal, and pharmacological fields. They are unique because of their large surface area and their numerous catalytic applications such as their use in automotive catalytic converters and as petrochemical cracking catalysts. Pt-NPs have been widely utilized not only in the industry, but also in medicine and diagnostics. The whole world has been utilizing plants for basic preventive and curative health care since time immemorial. Several plants have been search by the human race for the control of diseases. Human beings have used plants for the treatment of diverse ailments for thousands of years. According to the World Health Organization, over 80% of the world’s population, or 4.3 billion people, rely upon traditional plant-based systems of medicine to provide them with primary health care. In this study, the Platinum nanoparticles are synthesized from Centella asiatica L leaves and characterize the nanoparticles by UV-VIS, SEM, XRD.  The UV-VIS profile showed the peaks at 297.55, 300.25, 346.11 and 467.21 nm with the absorption 2.2307, 2.1279, 1.8237 and 1.0017 respectively. The X-ray structural diffraction pattern of the Pt-NPs produced using Centella asiatica L was proved and confirmed by the characteristic peaks observed in the XRD images. The SEM images showed the aggregates of reduced platinum nanoparticles. The changing of colour from yellow to brown then black indicates the synthesis of platinum. The results of this study suggested that the Pt-NPs synthesis from Centella asiatica L leaf extracts have many pharmacological properties which may used in the development of new drugs for maintenance of good health
