Development of non-enzymatic glucose electrode based on Au nanoparticles decorated single-walled carbon nanohorns

Gold nanoparticles (AuNPs)-based composite decorating with single-walled carbon nanohorns (SWCNHs) was synthesized and modified on a gold electrode for non-enzymatic glucose detection. The by simple covalent bonding method. AuNPs an average particle size of 40 nm are dispersed homogeneously the surface SWCNHs. Therefore, synergistic effect SWCNHs leads to excellent sensing performance. AuNPs/SWCNHs nanocomposites acted as fast redox probe oxidation exhibiting good performance, including high sensitivity (275.33 352.5 μA cm−2 mM−1), low detection limit 0.72 μM (S/N = 3). sensor also demonstrates stability, reproducibility, selectivity. Moreover, contents detected this in right agreement real value blood samples. In summary, study showed that have potential be used
