  • Re: Innova AFM laser alignment

    Hi Sontony42, What kind of tips and sample are you looking at? I assume everything worked before and you changed something. What happens when you try aligning e.g. an RTESPA and try scanning the supplied calibration grid in TappingMode? Regards, Stefan

  • Re: Nanoindentation using Dimension edge AFM (point spectroscopy)

    Hi Aarthi, Let me take a stab at this: Before performing force curves make sure that i) You select "relative movements" and turn the "linearizer, closed loop z" on. Realtive movements will relate all distances you type into the SW to the actual z-position at setpoint, i.e. the z-position at setpoint is set as "zero" and

  • Re: why "snap-in" and "pull-off" still occure in liquid.

    Hi Wang Shuo, The forces related to the (liquid) adhesion layer on surface in air are quite large indeed and therefore often dominate your signal. Stefan

  • Re: why "snap-in" and "pull-off" still occure in liquid.

    Hi Wang Shuo, The instabilities in the force curve where the cantilever suddenly accelerates towards the surface ("snap in") and releases from the surface ("pull off") are caused by attractive forces overcoming the spring force of the cantilever. This can happen in air and fluids. In air these regions are more pronounced as you have

  • Bio Market Campaign - Follow-up on "Amyloid fibrils" topic

    A few months ago, we launched a BMC topic called “Amyloid fibrils” based on a work by Jozef Adamcik and Raffaele Mezzenga. I’d like to inform you that the team recently released additional papers on the same topic: - Measurement of intrinsic properties of amyloid fibrils by the peak force QNM method (Adamcik et al, Nanoscale, 2012

  • Use AFM to read DNA/RNA/prot sequences

    Original question was: "Can you apply AFM to read the sequence of RNA or protein?" In the nineties, I remember some researchers started working on oligonucleotides on AFM tip. For instance they put AAA sequences on the surface and the corresponding TTT sequences on the tip. Then they did the same with GGG / CCC and found that the interaction
