Table 1. Atomic concentrations of MWNT, amino-functionalised MWNT and amino-functionalised MWNT bound enzyme from XPS experimental data.
Nanomaterial | Atomic concentration of oxygen (%) | Atomic concentration of nitrogen (%) |
MWNT | 1.0 | – |
Amino-functionalised MWNT | 13 | 5 |
Amino-functionalised MWNT bound enzyme | 20 | 14 |
All experiments in this study were carried out in triplicate with standard deviation below 5%.
