Mainsbridge and Thundat [J. Vac. Sci. Technol. B 9 (1991) 1259] recently reported STM images of chloroplast components. The goal of our work was to investigate the effects of sample preparation and imaging conditions, and to more clearly identify some of the structures that appear in chloroplast ima...
Previous work has shown that it is possible to image whole uncoated chloroplasts using scanning tunneling microscopy (STM), provided this is done in solution using tunnelling currents below about 100 pA. More recent images include some which suggest that the STM is sensitive to dynamic processes occ...
