文摘
- •
MWCNTs were successfully non-covalently functionalized with Cyt c.
- •
The partial denaturation of Cyt c due to the ultrasonication allowed the efficient dispersion of MWCNTs.
- •
The intimate interaction of Cyt c with MWCNTs facilitated the DET of the protein.
- •
The Cyt c that supports MWCNTs retained its electrocatalytic activity towards H2O2.
- •
GCE/MWCNT-Cyt c demonstrated to be a highly sensitive sensor for H2O2 quantification.
- •
GCE/MWCNT-Cyt c was successfully used for the quantification of H2O2 in real samples.
