bright pink cubic particles on a glass slide

This image shows hollow microparticles with a cubic geometry. The cap is loaded with a red fluorescent dye. The core is empty. An array of these microparticles are demonstrated in the image. The particles are designed for controlled delivery of vaccines and cancer treatments. The image was taken to better understand the mechanism of antigen release from the particles.
