Crowd surfing of graphene on a lipid monolayer

In the recent years a growing interest in graphene applications lead to the development of new biosensor devices. Graphene is a powerful sensor due to its extraordinary electron mobility, unique mechanical strength and optical properties.  Consequently, the

Immobilization of bilirubin oxidase on graphene oxide for oxygen reduction – when the charge matters

In recent years knowledge from nanotechnology, biotechnology and electrochemistry helped to develop extremely interesting devices – biofuel cells. In such devices, many different biomolecules have been employed for biologically catalyzed energy harvesting from energy rich organic molecules.

When graphene meets lectin for sensitive glycan analysis

The importance of glycans (chains of carbohydrates) in human body is relatively well known. They have a number of essential roles not only in physiology, but also in origin of various diseases. The majority of proteins and

Toxicity of graphene in lung alveolar epithelial cells

Graphene is a fascinating nanomaterial that has garnered significant scientific interest because of its unique properties such as superior thermal and electrical conductivity, high mechanical strength and unique optical properties. Due to this reason graphene has numerous

Downside of graphene – a miracle material

Any engineered nanomaterials should undergo thorough investigation on risk and health hazards imposed by them before available in the market for consumption. Graphene, a 2D carbon based material with hexagonal lattice structure along with its inherent physicochemical

Atomic wires of carbon: present status and perspectives

Carbon is all around us in different forms ranging from molecules to solids, minerals and nanostructures. Organic chemistry classifies alkanes, alkenes and alkynes hydrocarbons according to the different hybridization state of carbon atoms (sp3, sp2 and sp1,

Making the smallest possible fullerene molecules

It was in 1985 when the soccer ball appeared in chemistry. Spherical carbon cages were discovered, now known as the fullerenes and consisting of 60 carbon atoms in the shape of a soccer ball. Their discoverers have

Graphene: a nonlinear two-dimensional spring network

Graphene is one of the strongest materials in the world, which has an elastic modulus of 1.0 TPa and an intrinsic strength of 130 GPa (about 100 times of steel). Due to its nanoscale thickness, Graphene can

Enhanced absorption or transparency in hybrids of nanoparticles and graphene

The appealing side of nanotechnology lies in the fact that ordinary materials show surprising properties when their size is reduced to billionths of meters (nanometers). For example, we all know that silver is gray and gold is

Compact, all-optical, Terahertz wave generator

Terahertz (THz) wave is a kind of invisible light that has the frequency of about 1012 Hz. THz wave can path through different materials with small absorption or reflection, therefore this kind of wave can be used

Computational study of optical and electronic properties of metal-decorated Graphene

The computational methods for studying the various properties of nanomaterials like Graphene, have become extremely popular these days. Thanks to the ever increasing processor speeds. These methods include Density functional theory ( DFT ) and Time dependent density
