3D Surface Roughness Measurement of Core–Shell Microparticles

Researchers used AFM-in-SEM LiteScope to develop a new method for measuring the surface roughness of spherical microparticles. By integrating AFM with SEM, LiteScope enabled quasi-3D roughness data, providing more detailed analysis than traditional 2D methods.

We proudly congratulate the team of Deniz Hülagü, Charlie Tobias, Radek Dao, Pavel Komarov, Knut Rurack, and Vasile-Dan Hodoroaba on their impressive research into 3D surface roughness determination of core-shell microparticles using scanning electron microscopy (SEM). We’re thrilled that LiteScope AFM-in-SEM played a key role in enabling the high-precision measurements that were essential for the success of this study.

In their study, the team developed an algorithm to evaluate the roughness of spherical microparticles in 2D and extended this to a quasi-3D analysis by tilting the sample stage. The new method was tested on polystyrene core-iron oxide shell-silica shell particles and proved to be a valuable tool for routine quality control of microparticles. The roughness data was further validated with atomic force microscopy (AFM), showcasing the power of combining SEM and AFM for more comprehensive surface analysis.
