XRD patterns of biosynthesized Bauhinia. tomentosa Linn flower-powder extract-derived AgNPs. The XRD pattern displays diffraction peaks at 2θ = 37°, 49°, 63°, and 76° (corresponding to the planes of silver 111, 200, 220, 311), respectively. The XRD data and pattern confirmed the crystalline structure of biosynthesized AgNPs. No significant peaks corresponding to other crystalline phase impurities were detected.
