Carbon nanotubes

bioreceptors

  • Carbon nanotubes are studied as transducers due to their electronic properties and high surface. The methods of functionalization as well as the various functionalization modes have been developed:

 

Covalent attachment

Interaction through π- π stacking

chemical modification

Chemical modification

association

Association with conducting polymers

electro modification

Electrochemical modification

CN porphyrin

Association with metalloporphyrins

 

  • Carbon nanotubes and their association with other materials has been studied for various biosensors systems:

 

NTA copper

Modification with NTA/copper for his-Tag antibody immobilization and protein detection through redox
signal of copper

PP dendrimers

Association with conducting polypyrrole and redox dendrimers through π-π stacking interaction for DNA sensors development

 

CN dendrimers

Association with redox dendrimers through
chemical modification for aptasensors development
