Abstract EN
Ganoderma boninense (G.
boninense) has been identified as a major problem in oil palm industry which caused basal stem rot disease.
Identification of metabolite variation of healthy and G.
boninense-infected oil palm leaves at 14 days postinfection using NMR metabolomics approach followed by characterization of an electrochemical sensor based on a functionalized multiwalled carbon nanotube (MWCNT) layer-by-layer framework on modified screen-printed carbon electrode has been successfully determined.
Significant differences from the 1H NMR data were observed between healthy and G.
boninense-infected oil palm leaves, according to principal component analysis.
Gold nanoparticle-functionalized MWCNT and chitosan-functionalized MWCNT were deposited on a screen-printed carbon electrode and were applied for the electrochemical detection of healthy and G.
boninense-infected oil palm leaves.
The electrocatalytic activities of a modified electrode towards oxidation of healthy and G.
boninense-infected oil palm leaves at a concentration of 100 mg/L were evaluated using cyclic voltammetry and linear sweep voltammetry.
The limits of detection of healthy and G.
boninense-infected oil palm leaves were calculated to 0.0765 mg/L and 0.0414 mg/L, respectively.
The modified electrode shows a good sensitivity and reproducibility due to the unique characteristics of gold nanoparticles, chitosan, MWCNTs, and synergistic interaction between them.
