Visualization of Nano-Scale Elastic Modulus and Adsorption

The elastic modulus can be evaluated quantitatively by applying a theoretical model for calculating elastic modulus to
the force curve obtained by measuring the micro-forces acting between the probe and sample. The force distribution
can also be visualized in the vertical direction for nano-scale three-dimensional mechanical analysis.
˙ Mapping the Physical Properties of Polymer Films

Surface Shape Elastic Modulus Adhesion
Mapping polymer film surface properties clearly showed how elastic modulus and adhesive forces were distributed in
patches several tens of nanometers in size.

Mechanical Property Comparison of Different Samples

˙ Measuring the Shape of Contact Lenses

Surface Shape Deformation Adhesion
Physical properties were mapped for two different types of contact lenses, made by different manufacturers,
measured in an artificial tear solution. The map shows differences in surface properties of the two samples. The upper
contact lens deforms more easily and exhibits uniform adsorption forces.
