• enzyme, specific immobilization strategies, including electron mediators, should be considered [10][11][12]. In the last decade, the use of nano materials, especially carbon nanotubes (CNTs), in the construction of enzyme biosensors has received considerable attention. Because of their excellent

• ) from hyperthermophilic archaeon (Thermococcus profundus) was used to fabricate L-proline sensor based electrodes modified by layer-by-layer self-assembly immobilization of dye-linked L-proDH and ferrocene-labeled redox polyelectrolytes [9][28], which exhibited an amperometric current response to L
