NANOSENSORS uniqprobe qp-BioAC AFM probe top view (SEM image) These oft, drift-reduced AFM probes have become very popular among our users who appreciate the small variation of AFM cantilever force constant and resonance frequency. The partial coating of the uniqprobes designed for liquid environments has the advantage of preserving the mechanical properties of the AFM cantilevers while maintaining high optical reflection. Further benefits of the uniqprobe coating are stress-free AFM cantilevers with considerably less bending and reduced drift particularly for measurements in liquid environments. These properties make the AFM probes of the NANOSENSORS uniqprobe series ideal for applications in biology and life-sciences.

Science & Technology

Supplementary Figure S1 from Chao-Hung Chang et al. “Substrate properties modulate cell membrane roughness by way of actin filaments”: Images of membrane topography determined by atomic force microscopy (AFM). MEFs were seeded on the polymer coverslip-bottom μ-dishes coated with 0 or 10 μg/ml FN for 6 hours for the measurement of membrane roughness by AFM. The regions marked by the white squares in the bright-field images are displayed in the membrane topography. Scale bar, 10 μm. NANOSENSORS uniqprobe qp-SCONT AFM probes(long cantilever length 125 um, spring constant 0.01 N/m) were used.

Science & Technology

Supplemental Figure. 6. From Macrea et. al “A fibrin biofilm covers blood clots and protects from microbial invasion” Mechanisms and roles of fibrin film. A, Sneddon model used to calculate Young’s Modulus, where F is the force from the force curve, E is Young’s modulus, ν is Poisson’s ratio (0.5), α is the half angle for the indenter (15 degrees for our tips), and δ is the indentation. Note that this equation is only accurate with a half angle of 15 degrees for the first 200nm of indentation. B, Strength of the fibrin film in clots produced with plasma and thrombin with or without T101 (FXIII inhibitor ) investigated using atomic force microscopy (AFM). Fibrin fibres were visible under the film surface and these areas presented with stiffer Young’s modulus than fibrin film suspended between fibres. Grey lines in the zoomed-in images represent Young’s modulus scan area represented in the line force graphs. Scale bar - 2μm. C, Young’s Modulus was calculated for the suspended film and the film supported by fibers with and without T101 by fitting a Sneddon model to all AFM force curves found over the entire area that was imaged. 20 measurements were taken for each condition. **** P
