Novel mesoporous TiO2@DNA nanohybrid electrodes, combining covalently encoded DNA with mesoporous TiO2 microbeads using dopamine as a linker, were prepared and characterised for application in supercapacitors. Detailed information about donor density, charge transfer resistance and chemical capacitance, which have an important role in the performance of an electrochemical device, were studied b...

OBJECTIVE The aim was to evaluate the color and surface roughness of nanoparticle (C1) and nanohybrid (C2) composites after immersion in distilled water, acai juice, grape juice and red wine and repolishing. MATERIALS AND METHODS After recording the initial surface roughness and color, the specimens were divided into four groups according to the storage solution. The specimens were reassessed...

Herein, for the detection of highly explosive 2,4,6-trinitrotoluene (TNT) instantly and on-site, a fluorescence ratiometric probe using a dual-emission nanohybrid has been developed. The nanohybrid comprises blue-colored fluorescent graphene oxide (FGO) being conjugated with red-emitting manganese-doped ZnS nanocrystals (ZnS:Mn NCs), the latter being functionalized with hexamethylenediamine. Th...

This work explores the potential use of commercially obtained, carboxylated, single-walled carbon nanotubes (SWCNT-COOH) as nanocarriers for the antiparkinson drug, levodopa (LD). The resulting nanohybrid was characterized using materials characterization methods including Fourier transform infrared spectroscopy, Raman spectroscopy, elemental analysis, UV-vis spectroscopy and scanning electron ...

The research progress on the selective and sensitive fluorescent detection of nitrite anions has greatly relied on the development of new fluorescent materials. Herein, a novel nanohybrid exhibiting dual emissions in blue and red wavelength ranges is fabricated for the rapid, on-site, and sensitive detection of nitrite anions. Such a nanohybrid system consists of graphene oxide (GO-C6NH2) and g...
