Agilent 5500 AFM.
This instrument operates in air, in a purged atmosphere, humid environments as well as in liquid and electrochemical conditions.
A range of options are available and these include:
- AFM head: 90 micron scanner, contact, tapping mode and MAC mode
- Electrochemical cell and environment chamber
Imaging of well defined Au surfaces can be accomplished using Au single crystal beads that show 111 facets. The difference in the topography is one Au layer, or ~ 0.2 nm high.
- AFM was used in an electrochemical environment to look at the potential controlled liposome interaction with an octadecanol coated Au surface in an attempt to create a Solid Supported Bilayer.
- AFM measurements in air was used characterize protein adsorption onto a Au(111) facet:
- characterize the formation of ERGO on gold
