Redefining Carbon Electrodes as Hierarchically Designable Reaction Fields for Electrochemical Biosensing. [PDF]
SmallThis Perspective proposes viewing carbon electrodes as hierarchically designable reaction fields for electrochemical biosensing. Crystallinity, heteroatom dopants, edge sites, and pore size are highlighted as key structural variables governing electron transfer, mass transport, biomolecule immobilization, and local concentration.
