Diamond-based electrodes and biosensors are interesting in analytics because of their particular set properties, namely: large potential window, chemical inertness, low baseline current, stability, transparency. were shown to detect biological molecules such as neurotransmitters proteins, respectively. In this review, we summarise the different types diamond based on type detection (electrochemical or optical), functionalisation, target analyte. The last section presents a discussion analytical responses obtained with biosensors, according Electrodes work quite well for detecting small redox whereas more suited high molecular weight, DNA proteins.
