Graphene in combination with cucurbit[n]urils as electrode modifiers for electroanalytical biomolecules sensing.

摘要: Abstract Cucurbit[ n ]urils have been supported on graphene to develop sensitive and selective electrodes. The electrochemical response of modified electrodes containing or plus cucurbiturils has studied for three probe molecules including hydroxymethylferrocene, ferrocyanide methylviologen. It was found that the properties these are derived from an increase in electron mobility catalytic activity imparted by complexation molecular recognition due cucurbit[ ]urils. These graphene/cucurbit[ applied detection relevant biomolecules as tryptophan at 0.69×10 −7  M concentration.
