Atomic Force Microscopy

Our AFM can be used to scan various surfaces.

Introduction

Our AFM can be used to scan various surfaces ranging from metal, glass, and surfaces coated with biomolecules to live cells. It can be used to extract mechanical information such as adhesion, stiffness, and deformation. In addition, our AFM can precisely measure the bond strength and binding affinities of biomolecular interactions.
