Burnham, Nancy A.
A retinal protein complex known as bacteriorhodopsin was investigated by atomic force microscopy to determine whether it possessed qualities that make it favorable for use as a nanoscale actuator or sensor. Bacteriorhodopsin was tested in different forms (layered 2D crystals and disordered clusters), in three different environments (dry air, humidified air, and water), and on a number of surfaces (glass, charged glass, PDAC coated glass, and Gelpak TM adhesive surfaces). Bacteriorhodopsin was not observed to undergo any molecular motion.
