Abstract

Na⁺ is one of the most abundant metal ions and plays critical physiological roles in biological systems, therefore development of new Na⁺ sensors is becoming increasingly important. Currently many physical and chemical methods have been applied to detect Na⁺. In this paper, we developed a novel Na⁺ electrode based on a biomaterial, light-driven Na⁺ pump (NdR2). The photocurrent of the electrode upon excitation shows a characteristic positive polarity in Na⁺ solution at neutral pH. The peak current shows Na⁺ dependency within the concentration range from 1 to 200 mmol/L. The stability data show that the electrode is stable after being stored at 50°C for 90 min. As a novel biosensor, this Na⁺ pump-based electrode is of great significance in the study of ion transport mechanism and application of ion detection.
