Direct ascorbic acid detection with ferritin immobilized on single-walled carbon nanotubes

Direct ascorbic acid detection with ferritin immobilized on single-walled carbon nanotubes

Ferritin protein was noncovalently immobilized onto single-walled carbon nanotubes (SWNTs). This SWNT/ferritin composite was characterized using cyclic voltammetry, UV-visible spectroscopy, Raman spectroscopy, and high-resolution transmission electron microscopy. The use of the SWNT/ferritin film as...
