Green Synthesis of Silver Nanoparticles Generated by the Photoionization Process for Anti-biofilm Application

The present investigation focuses on microwave-assisted green synthesis of silver nanoparticles from Bombax ceiba bud powder (BBAgNP). In the present report, different microwave powers, i.e., 100 w, 180 w, 300 w, 450 w, 600 w, and 900 w, were used to prepare an aqueous extract of Bombax ceiba bud powder (BB) and in the fabrication of nanoparticles. The phytochemicals, especially polyphenols and flavonoids, present in the isolated extract served as a capping, reducing, and stabilizing agent for the developed nanoparticles. UV–Visible spectroscopy, particle size analyzers, EDX, SEM, and XRD were used to characterize the produced nanoparticles. UV–Visible analysis revealed that the strong absorption peak lies between 400 and 429 nm, which preliminary indicates the formation of BBAgNP. The XRD patterns of the developed nanoparticles revealed the crystalline character and anatase form of the developed nanoparticles. The SEM analysis of the developed BBAgNP exhibited that the average particle size of the developed BBAgNP was found to be in the range of 10–55 nm, and the shape of the developed BBAgNP was found to be spherical. The developed BBAgNP worked efficiently as a photocatalyst in the degradation of the malachite green dye solution and as an effective antimicrobial agent against B. cereus infections.
