| 英文摘要 | A novel iridium-needle electrode (Ir-NE) functionalized with agarose gel (AG-gel) and gold nanoparticles (AuNPs) was fabricated and adopted for the real-time in situ monitoring of natural labile copper (Cu ') in the culture medium of marine diatom. AuNPs possessed excellent electro-catalytic capacity towards the voltammetric determination of Cu, and AG-gel acted as the protective layer which enhanced the stability and lifespan of the electrode. The separation-catalysis detection mechanism based on the AG-gel and AuNPs made the electrode both high sensitivity and excellent anti-biofouling capability. In addition, the AG-gel/AuNPs/Ir-NE successfully achieved the real-time in situ monitoring of Cu ' in culture medium with Phaeodactylum tricornutum (P. tricornutum) as the model organism for marine diatoms. The correlation analysis between the concentrations of different Cu species and P. tricornutum cell density indicated that Cu ' or the Cu ' to total dissolved Cu (TdCu) ratio (Cu'/TdCu) might be a more accurate indicator of the bioavailability of Cu to marine diatom than TdCu. Furthermore, this electrode might also be extended to the real-time in situ determination of other labile metals in the culture medium of different microalgae, which provides an effective technique for studying feedback interactions between metals and algae. |
