[ 1 ] - Synthesis, characterization and photocatalytic properties of Iron oxide nanoparticles synthesized by sol-gel autocombustion with ultrasonic irradiation
Iron oxide (Fe2O3) nanoparticles were prepared by combination of sol-gel autocombustion and ultrasonic irradiation. The XRD pattern reveals that the crystallite size of sample is 36.7 nm and the phase identification shows hematite, syn has been crystalized. The morphology of the sample investigated by FESEM showed that particle size of the sample was about 76 nm. The optic...
[ 2 ] - Photocatalytic Removal of NOx Gas from Air by TiO2/Polymer Composite Nanofibers
Nitrogen oxides (NOx) released in atmosphere by fuels combustion lead to photochemical smog and acidic rains and have negative effects on human`s nervous system. In this research nanocomposite membranes of Poly Vinylidene Fluoride (PVDF)/ Poly Dimethylsiloxane (PDMS) and Titanium Dioxide nanoparticles (TiO2) with different weight percentage of TiO2 (0.5 and 1) for adsorption of NOx were prepare...
[ 3 ] - Au nanorods/ g-C3N4 composite based biosensor for electrochemical detection of chronic lymphocytic leukemia
Objective: With the increasing incidence of cancer and the dramatic effect of early detection on treatment and increase patient's life, many efforts have been devoted to making sensitive diagnosis systems. DNA as a biomarker for diagnosis of different types of cancers at the early stages of illness has attracted much attention.Methods: In this research novel electrochemical biosensor was ...
[ 4 ] - Au nanoparticles/g-C3N4 modified biosensor for electrochemical detection of gastric cancer miRNA based on hairpin locked nucleic acids probe
Objective: The annual incidence of cancer in the world is growing rapidly. The most important factor in the cure of cancers is their early diagnosis. miRNA, as a biomarker for early detection of cancer, has attracted a lot of attention. Methods: In this study, an electrochemical biosensor was developed to detect the amount of miR-106a, the biomarker of gastric cancer, by modifying a glass...
