High-resolution NMR structure of an RNA model system : the 14-mer cUUCGg tetraloop hairpin RNA [PDF]
, 2010 We present a high-resolution nuclear magnetic resonance (NMR) solution structure of a 14-mer RNA hairpin capped by cUUCGg tetraloop. This short and very stable RNA presents an important model system for the study of RNA structure and dynamics using NMR ...

Calculation of the effect of tip geometry on noncontact atomic force microscopy using a qPlus sensor
Beilstein Journal of Nanotechnology, 2013 In qPlus atomic force microscopy the tip length can in principle approach the length of the cantilever. We present a detailed mathematical model of the effects this has on the dynamic properties of the qPlus sensor.

Interpreting motion and force for narrow-band intermodulation atomic force microscopy
Beilstein Journal of Nanotechnology, 2013 Intermodulation atomic force microscopy (ImAFM) is a mode of dynamic atomic force microscopy that probes the nonlinear tip–surface force by measurement of the mixing of multiple modes in a frequency comb.

In this thesis, I develop a new measurement technique, name Hydraulic Force Spectroscopy, to address current limitation in the quantification of mechanical properties of 3D in vitro models. I integrate a traditional testing method of mechanobiology, micropipette aspiration, with principles from optical coherence elastography and civil engineering ...
