Bio-fabrication, characterization and Antimicrobial action of Cadmium Nanoparticles using Nyctanthes arbor-tristis (Leaves)

The present study states the reducing and capping potentials of Nyctanthes arbor-tristis leaves extract for the synthesis of cadmium nanoparticles. Synthetic conditions were optimized for synthesis of cadmium nanoparticles. Analytical techniques such as scanning electron microscopy (SEM) with EDS, Fourier transform infrared spectral analysis (FTIR), X-ray diffraction (XRD), UV visible spectroscopy (UV–VIS), etc. were used to detect the synthesized cadmium nanoparticles. The Cd NP’s crystallinity has been confirmed using the X-ray diffraction technique; their average crystalline size is 29.24 nm, and their dislocation density is 0.001169. Additionally, the surface morphology of synthesized nanoparticles demonstrated the spherical shape of Cd-NPs. The formation of Cd NPs is confirmed by a sharp rise at 3.2 keV, which is in line with the binding energies of cadmium nanoparticles. Phytochemical screening of the Nyctanthes arbor-tristis leaves extracts in water showed the presence of saponins, carbohydrates, glycosides, flavonoids, phenolic compounds, and tannins. Serratia and pseudomonas aeruginosa (Gram −ve) and Bacillus subtilis and M. luteus (Gram + ve) were used as human pathogens for the screening of the synthesized Cd NPs anti-microbial activity, and they were compared to the control antibiotic ciprofloxacin.
