In the last decade the use of nanomaterials has been having a great impact in biosensing. In particular, the unique properties of noble metal nanoparticles have allowed for the development of new biosensing platforms with enhanced capabilities in the specific detection of bioanalytes. Noble metal nanoparticles show unique physicochemical properties (such as ease of functionalization via simple chemistry and high surface-to-volume ratios) that allied with their unique spectral and optical properties have prompted the development of a plethora of biosensing platforms. Additionally, they also provide an additional or enhanced layer of application for commonly used techniques, such as fluorescence, infrared and Raman spectroscopy. Herein we review the use of noble metal nanoparticles for biosensing strategies—from synthesis and functionalization to integration in molecular diagnostics platforms, with special focus on those that have made their way into the diagnostics laboratory.

The antioxidants activities of sumac extract at various concentrations were evaluated in natural rice bran oil and canola oil stored at 65º.C, for 35 days. The concentrations of extracts added into oil were 0.1%, 0.3% and 0.5%. Antioxidants effect was determined by the measurement of peroxide value. In addition determine the fatty acid and rancidity of fats in the rice bran oil and canola oil proximate composition and active groups of sumac powder. The results indicated that the mean gross rancidity of fats of rice bran oil was 1%, 3.7%, 205% and 0.8%, 5.58%, 202% of canola oil. The percentage of saturated fatty acids of rice bran oil was 16.73% and 11.70%, respectively which was higher than the canola oil (3.93% and 12.64% respectively). On the other hand the percentage of Poly Unsaturated Fatty Acid of of rice bran oil (30.17% and 2.14%, respectively) which were lower than the canola oil (30.71% and 15.40% respectively). Extract at 0.5% in the rice bran oil after 14 into 35 days of storage had better antioxidant activity (12.04%, 15.22%, 17.3% and 21.46%) than the control sample. On the other hand, extract at 0.5% in the canola oil had better antioxidant activity except for after 14 and 35 days of storage. The rate of inhibition of autoxidation in the rice bran oil and canola oil increases by increasing the concentration of extracts of sumach after 35 days of storage. On the other hand, the percentage rate of inhibition of autoxidation in the rice bran oil due to the presence of total natural antioxidants was 1.25% but it was 3.75% in the canola oil. The results showed that Sumac extract is also promising as a source of natural antioxidants.

“…Furthermore, the spectra of the complexes exhibited weak bands between 500-545 cm -1 due to ν(M-N). This indicates the coordination of Tx and Tp with metal ions through the nitrogen atom [9][10][11][12] . The asymmetrical and symmetrical vibrations in OCNwere noticed at 2165 cm -1 and 1207 cm -1 respectively in the spectra of free ligand.…”

This work presents synthesis and study of a new mixed ligand metal complexes of 1,3,7-trimethylxanthine and 1,3-dimethyl-7H-purine-2,6-dione with some other ligands like SCN and OCN ions to give the general formula [M(Tx)2(Tp) )2XY] where M=Co(II), Ni(II), Cu(II), Zn(II) and Cd(II), Tx=1,3,7-trimethylxanthine, Tp= 1,3-dimethyl-7H-purine-2,6-dione, X= SCN and Y= OCN. The resulting products were found to be solid which have been characterized using UV-Visible and infrared spectroscopy. Elemental analyses were performed using C, H, N analysis and atomic absorption techniques. The magnetic susceptibility and the conductivity were also measured. The present results suggest that the 1,3,7-trimethylxanthine and 1,3-dimethyl-7H-purine-2,6-dione were coordinated with metal ions through the nitrogen atom. Thiocyanate ion was coordinated with metal ions through the sulfur atom and the cyanate ion was coordinated with metal ions through the oxygen atom.
