As a kind of biomass, the seaweed residue will cause resource waste and environmental pollution if it is discharged as at will. cheap easy biomass residue, its reuse has attracted more attention, tapped unexplored potential renewable biological resources. In this study, we synthesize carbon aerogel (CA) derived from an algae which utilized electrocatalyst for constructing electrochemical dopamine (DA) biosensor. Utilizing heightened disorder within CAs that was achieved through high-temperature pyrolysis augmentation active sites, show excellent electrocatalytic performance in detection DA can selectively detect with limit 0.033 μM. Furthermore, biosensor also employed to real samples satisfactory reproducibility stability. This study not only confirms feasibility introducing defects improve catalytic but extends application sensors monitoring various biomolecules.
