Carbon nanotubes-based electrochemical (bio)sensors for biomarkers

Electrocatalytic Activity of Nanohybrids Based on Carbon Nanomaterials and MFe2O4 (M=Co, Mn) towards the Reduction of Hydrogen Peroxide

“…The electrogenerated ones have interesting properties associated with the possibility to tune their size and composition . Carbon nanotubes (CNTs) have demonstrated to present additional advantages mainly connected with their high surface‐to‐volume ratio, their unique electronic properties and the presence of edge‐plane like defects that make them a very interesting material for electroanalytical applications . Since 2004, graphene has received enormous attention due to its high thermal conductivity, high electron mobility at room temperature, capacity to maintain high current densities, and easy functionalization, among others .…”

Ultralow Cost Electrochemical Sensor Made of Potato Starch and Carbon Black Nanoballs to Detect Tetracycline in Waters and Milk

“…The challenge is thus to seek materials to produce electrochemical sensors with high performance in terms of sensitivity and selectivity at low cost . Synergy is normally sought with nanomaterials such as carbon nanotubes (CNT) , graphene and its derivatives , nanodiamonds , carbon black (CB) , Printex 6 L carbon , oxides and carbons decorated with metallic nanoparticles . These nanomaterials are co‐imobilized in the sensing units with surfactants , polymer membranes (Nafion) , organic solvent , semiconducting polymers and biomolecules[18].…”

“…Electrochemical sensors are, in this context, a possible choice, for there is no need of sample preparation, analysis is fast, and using less expensive equipment. The challenge is thus to seek materials to produce electrochemical sensors with high performance in terms of sensitivity and selectivity at low cost .

Avidin and Glucose Oxidase‐non‐covalently Functionalized Multi‐walled Carbon Nanotubes: A New Analytical Tool for Building a Bienzymatic Glucose Biosensor

“…In the last years, carbon nanomaterials have played a crucial role in the development of electrochemical (bio) sensors [1][2][3][4]. In particular, carbon nanotubes (CNTs) have demonstrated to be extremely useful due to their oustanding properties [5][6][7][8][9]. As a consequence of the strong interaction between tubes, the incorporation of CNTs in electrochemical transducers to obtain CNTsbased electrochemical (bio)sensors has been one of the major challenges.…”
