GOPhotocatalystRecombination RateVisible LightGraphene oxide (GO) modified polyaniline (PANI) composite were synthesized by a simple sonochemical approach. The as-synthesized composite were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), UV-vis absorption spectra, FT-IR ...
TEM imaging of AptMUC1–Au NPs/GO revealed that the Apt–Au NPs had assembled homogeneously on the GO (seeSupplementary Fig. S1c). UV–Vis absorption and DLS measurements (seeSupplementary Fig. S2) revealed that AptMUC1–Au NPs/GO dispersed well (no aggregation) in PBS solution. We used...
Several studies have been conducted in this field. One study assayed the cytotoxicity of graphene oxide and graphene oxide loaded with doxorubicin on human multiple myeloma cells, and found that the cell proliferation was inhibited significantly by GO/DOX compared to pure DOX29. Another study represe...
Moreover, these UV PDs based on metal oxide semiconductor have gained significant interest because they are economical, easy to manufacture, and highly sensitive/responsive in the UV region [18]. To improve their sensitivity, variations of nanomaterial-based UV detectors have been developed, such ...
Graphene oxidecompositegelationfractal analysisoptical band gapelasticityGraphene oxide (GO) is a two-dimensional carbon material with similar one-atom thickness, and is a light material having extremely high strength and thermal stability [1]. Thus, GO is an efficient filler for the enhancement of ...

A facile sonochemical route for the synthesis of graphene nanosheets via reduction of graphene oxide (GO) has been reported. The synthesized graphene sheets are characterized using UV–vis spectra, Fourier transform infra-red (FT-IR) spectra, transmission electron microscope, X-ray photoelectron spectr...
In this study, the P25 TiO2 nanoparticles and graphene sheets (GSs) composite were prepared from a facile thermal reaction of graphene oxide. Its microstructures and photocatalytic properties were characterized and measured using X-ray diffraction (XRD), high resolution transmission electron microscopy ...
UV-vis spectroscopy (model 8453, Agilent, U.S.A) at 280 nm was used to measure the absorption intensity. Results and Discussion Investigation of synthesized graphite and graphene oxide IR spectra As can be seen in Fig. 2, the IR spectrum of GO indicates the presence of many factors on...
