| Abstract |
In recent years transitional metal oxide nanoparticles are extensively studied due to their wide range of applications in the field of physical, chemical and material sciences. Herein we report the synthesis of ultra-small and monodisperse chromium oxide nanoparticles through polyol method. Rhombohedral structure Cr2O3 nanoparticles with 2.05 ± 0.1 nm average diameter were characterized. Surface coating and metal – D-glucuronic acid bonding were confirmed from Thermo gravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FT-IR). The size dependence optical property were studied from UV-Visible spectrophotometer. The toxicity test was carried in two cell lines DU145 and NCTC1469 and found to be non-toxic up to 500 μM to both cell lines. The water proton relaxivities were studied to understand the possibility as MRI contrast agent. |
