Tencor Alpha-Step 200 Profilometer

profilometer

The Alpha-Step 200 is a 2D stylus profilometer with 5 Å vertical resolution in kÅ mode and 5 nm resolution in micron mode. Scan lengths can be manually set from 10 µm to 10 mm, with slow and fast scan rates. The horizontal resolution is 40 nm. This instrument is currently equipped with a 5 micron stylus (60°). The tracking force is currently set to 8 mg.

"Counting molecules, dodging blood cells: real-time molecular measurements directly in the living body"
The development of technology capable of continuously tracking the levels of drugs, metabolites, and biomarkers in situ in the body would revolutionize our understanding of health and our ability to detect and treat disease. It would, for example, provide clinicians with a real-time window into organ function and would enable therapies guided by patient-specific, real-time pharmacokinetics, opening a new dimension in personalized medicine. In response my group has pioneered the development of a “biology-inspired” electrochemical approach to monitoring specific molecules that supports real-time measurements of arbitrary molecular targets (irrespective of their chemical reactivity) directly in awake, fully ambulatory subjects.
