Why is graphene oxide used in drug delivery?
Its functional derivative graphene oxide (GO) possesses unique properties which make it more attractive for biomedical application: it is water soluble, provides a large platform with a variety of addends for convenient functionalization-based drug attachment, and exhibits fluorescence in visible/near-infrared spectrum …
What is graphene material?
Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometres.
What type of smart material is graphene?
Graphene is an ideal electrode material for electrochemical biosensors because of its high conductivity, large specific surface area and excellent electrochemical stability in aqueous media.
What products use graphene?
The first wave of graphene-based products are being used in the world of smartphones, wearables, batteries, virtual reality, sports equipment, super-capacitors and supercars… and that’s just the beginning.
What is the price of 1 kg graphene?
1kg Graphene Nanoplatelets Powder at Rs 15000/kg | Graphene Oxide | ID: 23566486412.
What are graphene-based materials?
Graphenes—monolayers of carbon atoms arranged in a honeycomb network (see the figure, left panel)—are prevalent in many carbonbased materials. For example, graphite can be considered as stacks of graphene layers.
What is graphene nanotechnology?
With recent advances in nanotechnology, graphene nanomaterials are being translated to applications in the fields of biosensing, medicine, and diagnostics, with unprecedented power. Graphene is a carbon allotrope derived from graphite exfoliation made of an extremely thin honeycomb of sp2 hybridized carbons.
Can I buy graphene?
How to buy Graphene? Graphene is available from a number of online and offline resellers. The price of graphene is not very attractive at the moment: around $300 (approx. 250 EUR) for 1 gram of pure, 3nm filtered graphene nanopowder.
Why is graphene so cheap?
This is because there is a lot of carbon ‘precursor’ waste in existence that could be eradicated and used to produce graphene. This process has the potential to reduce the cost of graphene and improve the environmental impact of the graphene industry and end-use sectors.
Why is graphene a smart material?
The high specific surface area and the excellent mechanical, electrical, optical and thermal properties of graphene make it an attractive component for high-performance stimuli-responsive or ‘smart’ materials.
