Graphene is a well-known two-dimensional material that exhibits preeminent electrical, mechanical and thermal properties owing to its unique one-atom-thick structure. Graphene and its derivatives (e.g., graphene oxide) have become emerging nano-building blocks for separation membranes featuring distinct laminar structures and tunable physicochemical properties. Extraordinary molecular separatio...

Tetracycline (TC) is a broad spectrum of antibiotic which is used to cure infectious diseases and cancer. It can cause harmful side effects due to its high absorption in all organs. On the other hand graphene is appropriate to carry drug and release it to special target, organ or cell. It may decrease the side effects of the drug dramatically by using low dosage of medicine. Graphene oxide (GO)...

Tumor-initiating cells (TICs), a.k.a. cancer stem cells (CSCs), are difficult to eradicate with conventional approaches to cancer treatment, such as chemo-therapy and radiation. As a consequence, the survival of residual CSCs is thought to drive the onset of tumor recurrence, distant metastasis, and drug-resistance, which is a significant clinical problem for the effective treatment of cancer. ...

Surface-enhanced Raman scattering (SERS) has demonstrated single-molecule sensitivity and is becoming intensively investigated due to its significant potential in chemical and biomedical applications. SERS sensing is highly dependent on the substrate, where excitation of the localized surface plasmons (LSPs) enhances the Raman scattering signals of proximate analyte molecules. This paper review...

We fabricated a 3D sandwich hybrid material composed of graphene and vertically aligned carbon nanotube forests (VACNTs) using chemical vapor deposition. The graphene was first synthesized on Cu foil. Then it was transferred to a substrate which had a pre-deposited catalyst Fe film and a buffer film of Al₂O₃ for the growth of VACNTs. The VACNTs were grown underneath the graphene and lifted up t...

Graphene, firstly isolated in 2004, is a new type of carbon materials, which contains a singleor few-layered sheet of Sp2-bonded carbon atoms. This special atomic structure gives graphene rich physical properties and wide potential applications. It has excellent electrical, mechanical, thermal and optical properties and has wide applications in nanoeletronic devices, transparent conductive film...

In this study a new method by Application of graphene oxide Nano sheets– Melamine –TioOxalic acid composite was exhibited as adsorbent for the elimination of toxic mercury (II) ions from aqueous solutions. The combine has the authority to adsorb the organic and inorganic combines. Through the immobilization of Melamine-TioOxalic acid (MTO) onto graphene oxide nanosheets, the desired composite w...

Using the Computational methods, the interaction effect of Tyrosine Amino acid on Graphene was investigated. For this purpose, the Density Functional Theory )DFT (in the ground state of 6-31G was used, and the interaction effects of Tyrosine on Graphene was investigated through attachment to three different base positions. Different parameters such as energy levels, the amount of Chemical Shift...

a organic-solution-processable functionalized-graphene (spfgraphene) material has been studied on pre-concentration and determination of trace mo(ii)ions. in this process, the effects of ph solution, elution conditions on pre-concentration of trace mo(ii) were studied and the effect of interfering ions was also investigated. a selective method for the fast determination of trace amounts of mo (...
