Extraction of photosynthetic electrons from plant or algal cells is a sustainable and promising route for the utilization of solar energy. Moreover, cellular extraction of photosynthetic electrons is more d-urable than that from isolate membrane components (photosyste-ms I, II, or thylakoids) due to inherently higher stability of cells. Here we prepared carbon nanotubes (CNTs) as electron transport highway from the chloroplasts to the electrolyte solution outside of the algal cells. Cell/CNT hybrid exhibited efficient photoelectron e-xtraction, and the process was visualized by scanning electroche-mical microscopy (SECM). Photosynthetic electron transport was quantified in single cell level for the first time by SECM analysis, and extension of such understanding to device levels is planned.
