Atomic Force Microscopy News and Research

RSS

Atomic force microscopy is a type of scanning probe microscopy used to image the surface of a substance, but at an atomic level. It can map the surface structure of different substances to understand how different structures interact with each other. This is done using a cantilever, which is similar to a vinyl record needle.

New calibration technique enhances accuracy of force measurements in microfluidic environments

A study introduces a novel method for calibrating the spring constant of FluidFM micropipette cantilevers, crucial for the accurate measurement of forces in microfluidic environments.
