Redox probe-free readings of a β-amyloid-42 plastic antibody sensory material assembled on copper@carbon nanotubes

The greatest achievement of this work relates to the elimination of a redox probe reading-stage in electrochemical biosensing, by incorporating the electroactive element within the working electrode. Overall, this approach opens doors for direct sample readings, avoiding the incubation of active redox elements on the sensing area for analytical purposes. In addition, the developed biosensor showed excellent proprieties in terms of response time and simplicity, showing a remarkable potential for on-site application in medical research and clinical diagnosis.
