Nanosized tin oxide was fabricated with a simple and cost-effective precipitation technique and was analyzed by performing x-ray powder diffraction (XRD), Fourier-transform infrared (FT-IR) spectroscopy, high-resolution transmission electron (HR-TEM) microscopy, energy-dispersive x-ray (EDX) and UV–Vis spectroscopy. The XRD results revealed that tin oxide particles possessed typical orthorhombic structure and exhibited improved crystallinity with annealing. Calcination at 250 °C produced predominantly orthorhombic SnO which transformed to SnO2 at higher temperatures of 500 and 750 °C. HRTEM and FESEM images showed existence of agglomeration within the particles of tin oxide. The absorption was found to increase up to a certain annealing temperature followed by a decrease, which was recorded via UV–Vis spectroscopy. The effect of annealing temperature on dye decomposition behavior of synthesized photocatalysts was studied. It was noted that annealing temperature affects the size of synthesized particles, band gap width and photoactivity of tin oxide. The sample prepared at 500 °C followed first-order kinetics and exhibited maximum photocatalytic reactivity toward methylene blue. The experimental results obtained from the present study indicate that SnO2 is a promising and beneficial catalyst to remove contaminants from wastewater and environment. The antimicrobial evaluation of SnO annealed at 500 °C against selected targets such as E. coli and S. aureus depicted significant inhibition zones in comparison with 250 and 750 °C samples. Furthermore, molecular docking predictions of SnO2 nanoparticles (NPs) were performed against active pocket of β-lactamase and DNA gyrase enzyme belonging to cell wall and nucleic acid biosynthetic pathway, respectively. The fabricated NPs showed good binding score against β-lactamase of both E. coli (− 5.71 kcal/mol) and S. aureus (− 11.83 kcal/mol) alongside DNA gyrase (− 9.57 kcal/mol; E. coli and − 8.61 kcal/mol; S. aureus). These in silico predictions suggested SnO2 NPs as potential inhibitors for selected protein targets and will facilitate to have a clear understanding of their mechanism of action that may contribute toward new antibiotics discovery.

“…The presence of an alkyl group (asymmetric C-H stretching) corresponds to the peak observed at 2927 cm −1 . Furthermore, the peak at 1455 cm −1 is attributed to the presence of carbonate minerals -CO 3 2− [30]. The peak at 462 cm −1 is due to the metal-oxygen stretching mode of ZnO and 627 cm −1 is due to the formation of the CdO bond [12].…”

“…The eggshell membrane (ESM) serves as a bio-template, reducing, and stabilizing agents while containing various collagen proteins such as amino acid types-I, V, and X along with glycine, alanine, and uronic acid. ESM also contains functional groups of amino, carboxyl, carbonyl, and aldehydes [30]. There exists few literatures for the synthesis of metal, its oxides and nanocomposites using ESM which include SnO 2 [30], β-NiMoO 4 [31], gold nanoparticles [32,33], SnO 2 [34], Co 3 O 4 [35], copper-containing bioactive glass/ ESM nanocomposite [36], Ag nanoparticles [37], CeO 2 [38], MnO 2 [39], TiO 2 [40], ZnO [41] and α-Fe 2 O 3 [42].…”

The following study was performed chiefly to analyze the antimicrobial activity of CdO/ZnO-ESM nanocomposites. A unique method was used for the synthesis of CdO/ZnO-ESM nanocomposites using an eggshell membrane as a bio-template which acts as both reducing and stabilizing agents; whereas cadmium nitrate and zinc nitrate were employed as metal precursors. The prepared samples were characterized by the following techniques such as TGA, PXRD, DRS-UV-Visible reflectance, FT-IR, HR-SEM, EDAX, Zeta potential, and Photoluminescence analysis. The prepared samples were subsequently tested for antimicrobial activity against Gram-positive bacteria (Staphylococcus aureus and Bacillus sp.) and Gram-negative bacteria (Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa, Salmonella enterica, and Vibrio sp.) using agar well diffusion method. The minimum inhibitory concentration was determined by the broth microdilution method. The maximum inhibition zone of 24 mm, was observed in Salmonella enterica at a concentration (30 μg/mL) of CdO/ZnO-ESM nanocomposites, while the highest MIC value was observed in Bacillus sp. at a concentration (1.95 μg/mL) of these nanocomposites. The result of this study showed that CdO/ZnO-ESM nanocomposites have an exceptional antimicrobial activity against both Gram-positive and Gram-negative bacteria.

“…It has been reported that the bio-waste material, the eggshell membrane was used for the synthesis of SnO 2 nanoparticles. The collagen proteins present inside the egg shell membrane acts as the reducing agent for the synthesis [19].Toxicity of green synthesized nanoparticles may depend on the experimental techniques, their size, and presence of capping agents [20]. Accumulating research evidences confirms that SnO 2 nanoparticles shows little toxicity.…”

A brisk and one-step green method of stannic oxide (Tin oxide) nanoparticles synthesis from the fruit essence of Averrhoa bilimbi has been described in this paper. Nanoparticle was synthesized using the method of co-precipitation and reduction with plant extract. The synthesized tin oxide nanoparticles have been characterized using different analytical techniques. Characterization was performed using UV-Vis Diffuse Reflectance Spectroscopy, Fourier-Transform Infrared Spectroscopy, Scanning Electron Microscopy, High-resolution Transmission Electron Microscopy, Energy Dispersive Spectroscopy, and X-ray Powder Diffraction. UV-Vis spectrum showed an absorbance in the range of 280 nm to 290 nm. The scanning electron microscopy analysis revealed the spherical morphology of the green synthesized nanoparticles and the energy-dispersive spectroscopy spectrum sights the intense peaks of Sn and O which validate the constitution of tin oxide nanoparticle. Further, X-ray diffraction analysis confirmed the formation of SnO2 nanoparticles in tetragonal crystal structure and the crystalline size of the nanoparticles estimated falls in the range of 2.6 nm. The nanoparticles size is determined to be at close range of 3.08 nm from the transmission electron microscopy studies. The exertion of the SnO2 nanoparticles was found against Klebsiella aerogenes and Staphylococcus aureus. Biosynthesized SnO2 nanoparticles showed antioxidant activity too. These findings support the use of tin oxide nanoparticles in distinct applications remarkably in medical field. SnO2 nanoparticles synthesis using the Averrhoa bilimbi fruit extract is being reported for the first time in this study to the best of our knowledge
