Title: Phytosynthesis and applications of bioactive SnO{sub 2} nanoparticles

A facile, eco-friendly, cost effective and versatile synthesis of SnO{sub 2} nanoparticles of size in the range 2.2–3.2 nm using fenugreek seeds is reported. The structural and morphological properties of SnO{sub 2} nanoparticles have been studied using X-ray diffraction, Transmission Electron Microscopy and Energy Dispersive X-ray spectroscopy. UV–visible spectra show a blue shift of the absorption band arising from quantum size effect. Studies on thermal conductivity, viscosity, antibacterial and antioxidant properties of the synthesized SnO{sub 2} nanoparticles highlight the possible applications in nanofluids and biomedical field. - Graphical abstract: Display Omitted - Highlights: • Bioactive SnO{sub 2} nanoparticles are synthesized using Fenugreek seeds. • Structural, morphological and optical characterizations have been done. • Thermal conductivity and rheological properties are reported. • Antioxidant and antibacterial activities are highlighted.
