“…Regarding metal oxide NPs, they often exhibit negative zeta potential, resulting in relatively weak interactions with bacterial surfaces due to the equilibrium of electrostatic forces. Conversely, for Gram‐negative bacteria, the more negative the surface potential, the weaker the surface interactions [54–58]. The interactions between SnO 2 NPs and the bacterial cell wall trigger ion release, leading to the generation of reactive oxygen species (ROS) on the NP surface.…”

The construction of SnO2 nanoparticles (NPs), specifically Te‐doped SnO2 NPs, using a simple and economical co‐precipitation technique has been thoroughly described in this work. NH3 served as the reducing agent in this procedure, whilst polyethylene glycol served as the capping agent. The primary goals of our work were to investigate the physicochemical properties of the synthesized SnO2 NPs and assess their potential use as antibacterial agents and photocatalysts. Scanning electron microscopy–energy dispersive X‐ray, ultraviolet light, Fourier transform infrared spectroscopy, X‐ray diffraction (XRD), and other analytical techniques were used to thoroughly analyze the NPs. Based on the full width at half maximum of the most noticeable peaks in the XRD spectrum, the Debye–Scherrer equation was used to calculate the crystallite sizes, which indicated the presence of a single tetragonal SnO2 phase. Particularly noteworthy was the exceptional photocatalytic activity of graphene‐assisted Te‐doped SnO2 NPs, achieving an impressive decomposition efficiency of up to 98% in the photo‐oxidation of methylene blue. Furthermore, our investigation delved into the antibacterial attributes of the synthesized SnO2 NPs against Escherichia coli and Staphylococcus aureus, demonstrating inhibitory effects on both bacteria strains. This suggests potential applications for these NPs in various environmental and medical contexts.

“…The inhibition zone which identified the antibacterial activity of SnO2 NPs in this study was comparable to, and even greater than, the SnO2 NPs observed in other studies. For example, the activity against E coli was higher compared to that demonstrated by the SnO2 NP synthesized co-precipitation method using DNA as the capping agent [54], and was also higher compared to SnO2 NPs synthesized using Vitex altissima [52]. The inhibition zone of 12 mm in this research was achieved with a concentration of 200 μg/mL, higher than the inhibition zone from the DNA-synthesized SnO2 NPs (10 mm) and Vitex altissima-mediated SnO2 NPs (1.1 mm).…”

“…Metal oxide nanoparticles tend to have a negative zeta potential, which easily interacts with this surface potential according to the electrostatic force equilibrium. In contrast, the more negative the surface potential of the gram-negative bacteria, the less the surface interaction [49][50][51][52]. Ions can be released from the interaction between SnO 2 NPs with the cell wall leading to the generation of reactive oxygen species (ROS) on the surface of the nanoparticles.…”

The present study reported biofabrication of flower-like SnO2 nanoparticles using Pometia pinnata leaf extract. The study focused on the physicochemical characteristics of the prepared SnO2 nanoparticles and its activity as photocatalyst and antibacterial agent. The characterization was performed by XRD, SEM, TEM, UV-DRS and XPS analyses. Photocatalytic activity of the nanoparticles was examined on bromophenol blue photooxidation; meanwhile, the antibacterial activity was evaluated against Klebsiella pneumoniae, Escherichia coli Staphylococcus aureus and Streptococcus pyogenes. XRD and XPS analyses confirmed the single tetragonal SnO2 phase. The result from SEM analysis indicates the flower like morphology of SnO2 nanoparticles, and by TEM analysis, the nanoparticles were seen to be in uniform spherical shapes with a diameter ranging from 8 to 20 nm. SnO2 nanoparticles showed significant photocatalytic activity in photooxidation of bromophenol blue as the degradation efficiency reached 99.93%, and the photocatalyst exhibited the reusability as the degradation efficiency values were insignificantly changed until the fifth cycle. Antibacterial assay indicated that the synthesized SnO2 nanoparticles exhibit an inhibition of tested bacteria and showed a potential to be applied for further environmental and medical applications.
