Article
A solution-based approach of chemical co-reduction of graphene oxide (GO) and HAuCl4 was used to prepare graphene/Au nanocomposite (GR/Au). The resulting hybrid material was characterized by scanning electron microscope and transmission electron microscope, which demonstrated that Au nanoparticles could been uniformly deposited on the GR sheets. Th...

A solution-based approach of chemical co-reduction of Au (III) and graphene oxide (GO) was used to prepare graphene/Au (GR/Au) nanocomposites. The gold nanoparticles (nano-Au) integrated in GR acted as spacers for inhibiting the aggregation of GR sheets. Scanning electron microscopy (SEM) and transmission electron microscope (TEM) results revealed...
Article
Graphene nanosheets were directly electrodeposited onto a glassy carbon electrode (GCE) from the electrolyte solution containing graphene oxide (GO); the resulting electrode (ED-GO/GCE) was characterized with scanning electron microscopy. A simple and rapid electrochemical method was developed for the determination of theophylline (TP), based on th...

... So, quick, simplified and inexpensive detection techniques for simultaneous determination of epinephrine and theophylline in biological fluids are of great importance. Several analytical procedures are available for epinephrine and theophylline that include spectrophotometry, high-performance liquid chromatography, capillary electrophoresis, chemiluminescence, surface-enhanced Raman scattering, gas chromatographymass spectrometry, as well as electrochemical methods [11][12][13][14][15][16][17][18][19][20][21][22]. ...
... The working electrode was a glassy carbon electrode (diameter = 3.0 mm), while the reference electrode was Ag/AgCl/KCl (saturated), and a spiral Pt wire was used as the counter electrode. Prior to use, the GC electrode was smoothed using alumina (0.5 μm down to 0.05 μm), then rinsed successively with distilled water and sonicated in ethanol and water [31][32][33][34] . It is important to note that all potentials were converted from Ag/AgCl to RHE using the following equation: ...
