Title: | Whole cell environmental biosensor on diamond | Authors: | Chong, K.F. Loh, K.P. Ang, K. Ting, Y.P. |
Issue Date: | 2008 | Citation: | Chong, K.F., Loh, K.P., Ang, K., Ting, Y.P. (2008). Whole cell environmental biosensor on diamond. Analyst 133 (6) : 739-743. ScholarBank@NUS Repository. https://doi.org/10.1039/b719881g | Abstract: | A whole-cell environmental biosensor was fabricated on a diamond electrode. Unicellular microalgae Chlorella vulgaris was entrapped in the bovine serum albumin (BSA) membrane and immobilized directly onto the surface of a diamond electrode for heavy metal detection. We found that the unique surface properties of diamond reduce the electrode fouling problem commonly encountered with metal electrodes. The cell-based diamond biosensor can attain a detection limit of 0.1 ppb for Zn2+ and Cd2+, and exhibits higher detection sensitivity and stability compared to platinum electrodes. © The Royal Society of Chemistry. | Source Title: | Analyst | URI: | http://scholarbank.nus.edu.sg/handle/10635/90497 | ISSN: | 00032654 | DOI: | 10.1039/b719881g |
