Nelumbo nucifera mediated synthesis of SnO2 NPs: Structural, morphological and biomedical applications

Nanoparticles (NPs) prepared from green-synthesize offer a safe, economical, eco-friendly, and effective alternatives to conventional methods that yields biocompatible NPs with improved properties for usage in biomedical applications. In this study, SnO2 nanoparticles were fabricated using Nelumbo nucifera extract. PXRD analysis revealed a tetragonal crystalline structure with an average crystallite size of ∼10 nm. The band gap energy Eg was determined to be 3.8 eV, and a significant absorption peak observed at 271 nm using UV–vis analysis. FESEM images confirmed irregular morphology with particle sizes ranging from 30 to 60 nm. The synthesized SnO2 nanoparticles demonstrated notable biomedical potential, as evidenced by α-amylase inhibition and MTT assay results.
