Veeco AFM Research Spotlight- Mapping Material Properities using Harmonics

Mon, 03 Mar 2008 16:00:00 EST

With traditional SPM cantilevers, harmonic signals are severely attenuated by the transfer function of the cantilever. While working with novel cantilever designs to amplify a single harmonic at Stanford University, Dr. Ozgur Sahin realized that the torsional motion of the cantilever typically has much higher bandwidth than its flexural motion, and that many harmonics could be observed simultaneously by moving the tip laterally to an off-axis position on the cantilever.

Veeco AFM Research Spotlight- Biomolecular Interactions & Force Spectroscopy

Sat, 01 Mar 2008 11:25:00 EST

Ching-Hwa Kiang's current research focuses on understanding biomolecular interactions using single-molecule manipulation and force spectroscopy. One application of these techniques is the study of protein folding. Protein misfolding defects are believed to be involved in a number of neurodegenerative diseases including Alzheimer's and Parkinson's diseases. It has therefore been a longstanding goal to understand how proteins fold. The atomic force microscope (AFM) has been used to study protein folding by stretching a single protein between a sample surface and the AFM cantilever, and then measuring the unfolding forces. However, interpretation of the results from these nonequilibrium measurements is not straightforward. The most common analysis approach yields only the unfolding rate and width of the unfolding potential, but does not readily provide information on the free energy barrier.
