9.3.2 Tip Suggestions
Soft cantilevers, particularly oxide sharpened tips, produce the best results
for biological applications. These tips are typically 100 microns long,
narrow-legged with oxide sharpened silicon-nitride tips. Models DNP-S or
DNP-STT are good examples. Users should experiment to find which
cantilevers work best for their sample.
Note: For additional information on selecting
a cantilever, please refer to the Digital
Instruments Veeco website (www.di.com).
Removing Organic Contamination
Contaminants on the cantilever tip may limit the AFM’s resolution. Use
ultraviolet light to remove contaminants as follows:
1. Place the fluid cell with installed tip face-up on a clean surface.
2. Position a UV lamp very close (3-5mm) to the fluid cell and
irradiate the unit for two minutes at full intensity.
