Zusammenfassung:	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 images. We have imaged gold-coated chloroplasts in air, and bare chloroplasts in solution. Results obtained include images of whole chloroplasts several micrometers in diameter, and images which show molecular-scale structure on the chloroplast outer membrane.
