Carbon Nanomaterials in Biosensors: Should You Use Nanotubes or Graphene?

“…[152] Similar improvements in electrode performance were more recently observed for composite electrodes made with CNTs and ionic liquids, which offer high stability, high electrical conductivity, and Biosensors Angewandte Chemie extremely low vapor pressure. [153,154] However, caution is needed when interpreting these results. The mechanism of favorable electrochemistry for CNT-based electrodes remains controversial because, as we discussed above, most CNTs contain metal impurities derived from the catalysts used in their growth, which are at least partially responsible for the observed electrochemical activity.…”

A Sensitive Simultaneous Determination of Adrenalin and Paracetamol on a Glassy Carbon Electrode Coated with a Film of Chitosan/Room Temperature Ionic Liquid/Single‐Walled Carbon Nanotubes Nanocomposite

“…K 3 Fe(CN) 6 exhibited a pair of quite reversible redox peaks at bare GC and modified electrode but at the modified electrode the redox peaks height values are larger than GC. On the other hand, under the same conditions, the I p is linear to the square root of scan rate (ν 1/2 ) on GC and SWCNTs-CHIT-IL/GC electrodes.…”

“…4,5 Recently, preparation of the modified electrodes with room-temperature ionic liquids and nanomaterials composite has achieved considerable attention for combining their unique advantages to develop the performances of electrochemical devices. [6][7][8] A biocompatible polymeric matrix, chitosan (CHIT) displays excellent film-forming ability, high water permeability, susceptibility to chemical modifications and chitosan chains can associate with CNTs to form a biocompatible nanotube aqueous solution. CHIT has been widely used as an immobilization matrix for biosensors and biocatalysis.…”
