Pharmacological applications of metal nanoparticles derived from Caralluma sarkariae species

Abstract

The present research is focused on synthesis of silver/gold nanoparticles using Caralluma sarkariae root extracts (CSR-AgNPs and CSR-AuNPs) used as capping/reducing agents and successfully carry out the pharmacological studies. The as-prepared CSR-AgNPs and CSR-AuNPs were systematically characterized using various analytical techniques. Moreover, the formation of CSR-AgNPs & CSR-AuNPs was confirmed by SPR values observed at 432 and 537 nm in UV–Visible spectroscopic. Morphological information of CSR-AgNPs & CSR-AuNPs were investigated using scanning electron microscope (SEM) and high-resolution transmission electron microscope (HR-TEM) analysis and as-synthesized nanomaterials were spherical in nature with mean size of 20 and 22 nm, respectively. The prepared nanoparticles clearly proven that the as-prepared nanoparticles exhibit high performance efficiencies in terms of in vitro antioxidant, anti-inflammatory, antibacterial and antifungal activities. The wound healing activity of as-fabricated CSR-AgNPs and CSR-AuNPs were carried out separately using three different methods such as in vitro scratch assay, MTT assay, and fluorescence staining methods. Furthermore, the fibroblast L929 cells were used for the wound healing activity of both nanoparticles and aqueous CSR extract in in vitro scratch assay. Moreover, the wide range of diseases could be treated by using the nanoparticles as-synthesized due to their outstanding pharmacological activities.
