Note: Carbon nanotubes (CNT) due to their special physicochemical properties such as thermal, magnetic, optical or electrical conductivity.
Biological reactions and toxicity to carbon nanotubes, and CNT nanotubes as well as other nanomaterials, have been shown to have numerous physical properties such as length, diameter, surface area, tendency to condense, dispersion, presence and nature of the remaining catalyst. Also, the chemical functional groups of these nanomaterials depend on these reasons, and especially due to the growing efficiency of carbon nanotubes in biosensors and the study of CNT toxicity in biological environments, and efforts to address this problem are generally necessary in bio. Sensors and biological environments in which CNT interacts with electron properties and interferes with their structure are likely to reduce the toxicity of carbon nanotubes to electrons in porous nanostructures . One way to reduce CNT toxicity It is suggested to use a surface coating on the nanotubes . Placing the appropriate functional groups is called functionalization technique. Various studies have shown that exposure to pure carbon nanotubes significantly reduces cell proliferation and cell cycle, apoptosis and necrosis in the structure of biosensors and Biosensors can be separated and coated with specific molecules as a result of the process of functionalizing carbon nanotubes and biological nanosensors, which typically cluster . Carbon nanotubes (2600 g / 2) are polyaromatic compounds with a surface area greater than m . The lateral surfaces of the nanotubes are highly hydrophobic.
Structure and structure (fullerenes) in nature contain five allotropes of diamond, graphite, nanotube, amorphous carbon and fullerene, all of which are solid. The base of fullerenes is the plates in graphite, with the difference that in the atomic structure of fullerenes, instead of the regular hexagons in graphite plates, there is a series of regular hexagons and pentagons that are placed side by side. And form fullerene butter. The placement of these pentagons and hexagons is essential to form a spherical structure. In fact, without the presence of pentagons in the graphene structure, spherical structures cannot be obtained from the graphene plates. Fullerenes are identified by the number of atoms in their building. The letter C is used to denote fullerenes, which denotes the carbon atom in their structure. The letter C is followed by the number of carbon atoms in the fullerene spherical lattice unit. For example, the C60 molecule has 60 carbon atoms. The number of atoms in fullerenes produced so far ranges from 28 to hundreds of carbon atoms.
Conclusion:
Carbon nanotubes (CNTs) due to their special physicochemical properties such as thermal, magnetic, optical or electrical conductivity.
