Time-release drug capsule, SEM

Time-release drug capsule, coloured scanning electron micrograph (SEM). Once swallowed, the outer layer of the capsule breaks, releasing the smaller capsules (balls) that contain the drug. These are coated in layers that dissolve at different rates, ensuring the drug they contain is released at different times. Magnification unknown
