Hi, I have recently purchased some SNL10s to image some short (100nm) DNA strands. I need to detect whether the DNA strands are bent or straight. (sausage or banana in the AFM). I am using a dimension 3100 at the department of chemistry in Cambridge University. Initially I tried using tap150s in air but these do not seem to have high enough resolution

During my PhD, I did an experiment to check the effect of the laser on the local temperature. Of course I could not directly wire the thermocouple to the cantilever but I put it very neerby (less than 100 um) inside a dish filled with conductive buffer. After half a day of equilibration, the temperature only increased by 3-4 deg C... It was an Al coated

Symply because we use standard reference mixtures of polymers. For HarmoniX measurements for instance, you have the choice between: PS (polystyrene matrix) / PE (inclusions of polyolefin elastomer): PS is ~2GPa and PE ~100MPa or: PS / EPDM (monomers of propylene diene: PS is ~2GPa and EPDM is ~10MPa, is you want to target softer samples. If you use

Electrochemical SPM traditionally refers to operating the AFM (or STM) in a fluid environement, aqueus or not, and perform an electrochemical experiment. At the same tip the SPM tip is used to monitor the surface. In another form the AFM tip can also act at an electrode and the electrochemical experiment can be carried out at the location of the tip

Z Resonance refers to the resonance frequency of your AFM z-scanner assembly. In PeakForce Tapping you drive the z-piezo with a sinusoidal wave and want to avoid hitting the scanner resonance at that frequency. Hence the decision to use a conservative 2 kHz on the ICON system to stay way below any z resonance.
