What are the advantages of nanotubes?
CNTs have proven to be an excellent additive to impart electrical conductivity in plastics. Their high aspect ratio (about 1000:1) imparts electrical conductivity at lower loadings, compared to conventional additive materials such as carbon black, chopped carbon fiber, or stainless steel fiber.
What is carbon nanotubes Slideshare?
Carbon nanotubes (CNTs) are an allotrope of carbon. Allotrope: each of two or more different physical forms in which an element can exist. ● CNTs are long, thin cylinders of carbon. ● They can be thought of as a sheet of graphite (a hexagonal lattice of carbon) rolled into a cylinder.
How are carbon nanotubes used in medicine?
Carbon nanotubes (CNTs) are very prevalent in today’s world of medical research and are being highly researched in the fields of efficient drug delivery and biosensing methods for disease treatment and health monitoring. Current cancer therapy primarily involves surgery, radiation therapy, and chemotherapy.
What are nanomaterials and their applications?
Nanomaterials can be used in different applications such as in medicine, electronic device, sunscreens, military applications, photovoltaic cells, paints, catalysts, etc. These can be used in solar cells to produce clean energy, nanotechnologies in coatings, and sonochemical decolorization of dyes.
What are nanotubes used for GCSE?
Nanotubes have high tensile strength , so they are strong in tension and resist being stretched. Like graphene, nanotubes are strong and conduct electricity because they have delocalised electrons. Nanotubes can be added to other materials, for example in sports equipment, to make them stronger.
What are the applications of carbon?
Impure carbon in the form of charcoal (from wood) and coke (from coal) is used in metal smelting. It is particularly important in the iron and steel industries. Graphite is used in pencils, to make brushes in electric motors and in furnace linings. Activated charcoal is used for purification and filtration.
What are carbon nanotubes and its applications?
Carbon nanotubes (CNTs) is smart carbon materials which significantly utilized for the potential applications, large-scale synthesis, structural evaluation, and physical as well as chemical properties of carbon nanotubes and/or related conjugated carbon materials.
Why are nanotubes used in drug delivery?
Carbon nanotubes are promising drug delivery platforms that can be functionalized with a variety of biomolecules, such as antibodies, proteins, or DNA. Carbon nanotubes can easily penetrate cells, delivering drugs directly to the cytoplasm or nucleus.

What are nanotubes used for BBC Bitesize?
How are carbon nanotubes used in biomedical applications?
FUNCTIONALIZATION OF CARBON NANOTUBES FORBIOLOGICAL APPLICATIONS:• Raw carbon nanotubes have highly hydrophobicsurfaces, and are not soluble in aqueous solutions.• For biomedical applications, surface chemistry orfunctionalization is required to solubilize CNTsimprove biocompatibility and low toxicity.•
What are the properties of a carbon nanotube?
Carbon nanotubes have a range of electric, thermal, and structural properties that can change based on the physical design of the nanotube. Single-walled carbon nanotube structure Single-walled carbon nanotubes can be formed in three different designs: Armchair, Chiral, and Zigzag.
What kind of material trap fullerene in carbon nanotubes?
Peapod :- A carbon peapod is a novel hybrid carbon material which traps fullerene inside a Carbon nanotube. CUP-STACKED CARBON NANOTUBES :- CSCNTs exhibit semiconducting behaviours due to the stacking microstructure of graphene layers. 11.
What are the environmental risks of carbon nanotubes?
Environmental concerns. The environmental risks of nanotubes are still unclear[6]. Naturally occurring carbon is fairly benign, and is largely unregulated, but nanotubes interact with the environment differently. There have been several studies performed to test the effects of carbon nanotubes on living systems.
