Carbon Nanospikes Demonstrate Enhanced Electrochemical Performance Compared to Carbon Nanotubes/Fibers
CNSs were grown on metal wires and fabricated into microelectrodes. CNS microelectrodes have greater surface roughness and faster electron transfer kinetics compared with CNT and CF microelectrodes.

Scientific Achievement

Carbon nanospikes (CNSs) have a short, densely packed, defect-filled surface that exhibits remarkable electrochemical properties compared with carbon nanotubes (CNTs) and carbon fibers (CFs).

Significance and Impact

CNSs can be widely used as a material for neurotransmitter sensing.

Research Details

– CNSs and CNTs were successfully grown on metal wires using chemical vapor deposition and fabricated into microelectrodes. – Electrochemical properties of CNS, CNT, and CF microelectrodes were evaluated. – CNSs exhibit greater surface roughness and numerous defect sites that improve current density, electron transfer kinetics, and adsorption.   Q.
