The screencast about NanoWorld AFM probes for Magnetic Force Microscopy held by Dr. Marco Becker has just passed the 1000 views mark. Congratulations Marco!
NanoWorld offers two types of MFM tips:
– MFMR – This type of magnetic AFM tip is coated with a hard magnetic coating on the tip side and yields a very high force sensitivity, while simultaneously enabling tapping and lift mode operation.
– S-MFMR – These magnetic AFM tips are coated with a soft magnetic layer on the tip side and are designed for the measurement of magnetic domains in soft magnetic samples.
Got questions about AFM probes that you’ve always wantend to ask? You’re welcome to pass by NanoAndMore USA booth no. 610 at the 2018 MRS Fall Exhibit this week and meet NanoWorld CEO Manfred Detterbeck there.

In the article “Direct observation of dynamic interaction between a functional group in a single SBR chain and an inorganic matter surface” Ken-ichi Shinohara and Yuu Makida use atomic force microscopy (AFM) video imaging to closely investigate the behaviour of functionalized and unmodified styrene-butadiene rubber (SBR), as models for tire rubber, on mica surfaces.
“Using AFM video imaging, we tracked the behavior of individual SBR polymer chains on mica surfaces to reveal how polymer modification affects the interaction of SBR with mica surfaces. We measured the diffusion coefficients and spring constants of single SBR polymer chains for the first time, demonstrating that it is possible to parameterize the relationship between the molecular dynamic structure of a polymer and rubber properties of the vulcanized compound.”*
NanoWorld Ultra-Short Cantilevers (USC) for Fast-/High-Speed AFM ( USC-F1.2-k0.15 ) were used
Figure 3 from “Direct observation of dynamic interaction between a functional group in a single SBR chain and an inorganic matter surface” by Ken-ichi Shinohara & Yuu Makida: (A) Single-molecule imaging of the structure of two isolated polymer chains of carboxyl-functionalized styrene-butadiene rubber (SBR) on mica under n-octylbenzene at 25 ± 1 °C (Movie S5). Snapshot AFM image of a fast-scanning atomic force microscopy (AFM) movie; X: 200 nm, Y: 150 nm, Z: 7.2 nm. Rate: 5.0 fps. (B) A snapshot of all-atom MD simulated structure of a single chain of carboxyl-functionalized SBR (CPK model) in n-octylbenzene as a solvent. Dynamic globular (ball-like) structures were formed partially in a SBR chain. The position of carboxyl group was indicated by an arrow. The backbone was displayed in purple. Solvent molecules are indicated by line model and hydrogen atoms are omitted for simplified to view.
