dc.description.abstract | Sensitivity of Anthrax protective antigen (PA) detection has been improved by directly immobilizing a PA-specific peptide onto a multi-wall carbon nanotube (MWCNT). The MWCNT was covalently immobilized onto a polyaniline (PANI) electrode, which was prepared via electropolymerization of the aniline monomer onto a glassy carbon electrode (GCE). Then, the PA-specific peptide was covalently immobilized to the MWCNT layer for measurement. When comparing this technique to that of PA immobilization on an insulting self assembled organic layer, the advantages of the MWCNT are clear. The MWCNT sensor resulted in enhanced electron transfer across the sensing layer. The resulting limit of detection (LOD) was 0.4 pM, a 13-fold improvement over that of our previous self-assembled organic layer was used for immobilization of the same peptide. Neither positive nor negative interferences were observed when a sample containing both 100 pM PA and bovine serum albumin (BSA) was measured, indicating good selectivity of the proposed sensor. | en_US |
