- Since the reaction time is unknown (and perhaps is two-directional),
- what means are there for detecting when the reaction has taken place?
- I guess you could withdraw the tool, and then check to see whether a
- hydrogen is attached (test tool length using a tunneling current?).
- Could some electronic method be used before withdrawing the tool?
