Graphene sheets, which possess unique nanostructure and a variety of fascinating properties, are considered as promising nanoscale building blocks new nanocomposites, namely support material for the dispersion metal nanoparticles. One methodologies used to prepare graphene sheets is chemical exfoliation graphite in aqueous medium, produces oxygen functionalized sheets. Here, we show that presence functionalities at surface provides reactive sites nucleation growth gold Gold nanoparticles...
Graphene is a two-dimensional new allotrope of carbon, which stimulating great curiosity due to its superior mechanical, electrical, thermal and optical properties.
Nano-graphene oxide (GO) has attracted great interest in nanomedicine due to its own intrinsic properties and possible biomedical applications such as drug delivery, tissue engineering hyperthermia cancer therapy. However, the toxicity of GO nanosheets is not yet well-known it necessary understand entry mechanisms into mammalian cells order avoid cell damage human toxicity. In present study, cellular uptake pegylated ca. 100 nm labeled with fluorescein isothiocyanate (FITC-PEG-GOs) been...
Nano-graphene oxide (nano-GO) is a new class of carbon based materials being proposed for biomedical applications due to its small size, intrinsic optical properties, large specific surface area and easy functionalize. To fully exploit nano-GO reproducible method production utmost importance. Herein we report, the study sequential fracture GO sheets onto with controllable lateral width, by simple on mechanism that describe as confined hot spot atomic fragmentation/reduction promoted...
Graphene oxide (GO) and functionalized carbon nanotubes (f-CNTs) (each in the concentration range of 0.01-1.00 wt/wt%) were investigated as reinforcing agent a poly(methyl methacrylate) (PMMA)/hydroxyapatite (HA) bone cement. Mixed results obtained for changes mechanical properties determined (storage modulus, bending strength, elastic modulus) reinforced cement relative to unreinforced counterpart; that is, some property increased while others decreased. We postulate this outcome is...
Abstract Synthetic Ag‐bacterial cellulose nanocomposites are reported here and their performance as surface enhanced Raman scattering (SERS) substrates was investigated using thiosalicylic acid 2,2′‐dithiodipyridine analytes. These nanocomposite materials act natural sponges when immersed in aqueous or ethanolic solutions allowing capture SERS detection of certain dissolved molecules. The limits for the above organic analytes reached concentrations low 10 −4 mol·dm −3 considerably lower than...
Polycaprolactone (PCL) electrospun scaffolds have been widely investigated for cartilage repair application. However, their hydrophobicity and small pore size has known to prevent cell attachment, proliferation migration. Here, PCL was blended with gelatin (GEL) combining the favorable biological properties of GEL good mechanical performance former. Also, polyethylene glycol (PEG) particles were introduced during electrospinning polymers blend by simultaneous electrospraying. These...
Graphene oxide (GO) assists a diverse set of promising routes to build bioactive neural microenvironments by easily interacting with other biomaterials enhance their bulk features or, alternatively, self-assembling toward the construction biocompatible systems specific three-dimensional (3D) geometries. Herein, we first modulate both size and available oxygen groups in GO nanosheets adjust physicochemical biological properties polycaprolactone–gelatin electrospun nanofibrous systems. The...
