The last time I spoke about this project two years, we were at the beginning, Omri had just started his MSc and had worked out that the width measurements under strain were not of a consistent series.
This is now fixed, and after two years of molecules flying off nanotubes with full movie descriptions of how they escaped, we worked out how to get them to stay there. (Do you see Heidi and David saying ``stay'' to the dogs?)
The ``stay secret'' for the nanotubes is Yuval Yaish and Sharon Maliniak's suggestion to use wider nanotubes. We have been able to proceed and measure changes in frequency as a function of added mass.
