Synthesis, Characterization and Antimicrobial Activity of Bombax ceiba Fruit Extract based Palladium Nanoparticles

The synthesis of nanoparticles using different parts of plant extracts offers a cost-effective, efficient and environmental friendly option for applications in biomedical research, the environment and energy. This work presented a way to fabricate palladium nanoparticles (Pd NPs) using Bombax ceiba fruit extract in the non-calcined and calcined formed. Pd NPs have been applied as antimicrobial agents against a number of bacterial and fungal species after being investigated using XRD, FTIR, SEM, TEM and EDX methods. The synthetic approach was found to be cost-effective, efficient and safe. The antimicrobial study was conducted for both non-calcined as well as calcined Pd NPs. The findings of the antibacterial investigation demonstrated that Pd NPs were particularly effective against A. niger and B. subtilis, with zones of inhibition of 11.4 and 20.3 mm, respectively. The effectiveness of Pd NPs against bacterial and fungal species was found to be in the order of B. subtilis > E. coli > S. aureus and A. niger > C. parapsilosis, respectively.
