| Each microsphere is coated with a radioactive isotope which emits beta radiation. |
| The rate of microsphere biodegradation, which depends on the size and composition of the microspheres, determines when and how quickly the antigens are released. |
| The low-dielectric properties of the microsphere appear to dominate the spectroscopic properties of the hydrophobic chromophores. |
| The basis of IMS is a uniform, superparamagnetic, polystyrene microsphere called Dynabeads®. |
| The matrix is preferably in the form of a microparticle such as a microsphere or microcapsule, a film, an implant, or a coating on a device such as a stent. |
| Improved patient selection criteria and technical changes to microsphere delivery have reduced the risks of complications and death. |
