Micro-capsules are increasingly being studied as models for cells, as drug delivery vehicles, and even as devices for enhanced oil recovery form porous substrates. As such, understanding of their mechanical properties is critical for rational design and optimal performance. Here we describe experiments using a Cantilevered-Capillary Force Apparatus to probe the dynamic (or complex) modulus of micro-capsules under axial compression. The micro-capsules used in this study are approximately 200 microns in diameter and are composed of a sunflower-oil core surrounded by a gellan-gum shell.
