Abstract: A method of forming polymeric microspheres for biomedical applications includes forming polymeric microspheres by an emulsion/aggregation process from a precursor monomer species, and treating the polymeric microspheres to attach a biomedical functional material to the polymeric microspheres, where the polymeric microspheres have an average particle diameter of from about 1 to about 15 microns with a narrow particle geometric size distribution. The biomedical functional material may be, for example, a radioactive material, a radioactive precursor material, a bioactive agent, or a ligand.

Abstract: Superradiance is generated by generating coherent radiation in the 10 gigahertz (1010) to terahertz (1012) regions of the electromagnetic spectrum. The radiation is produced by pulsing a micro crystal of a molecular magnet in a cavity or between a pair of superconductor mirrors at Kelvin or milli-Kelvin temperatures. The coherence and source of the radiation result from enhanced quantum mechanical spin tunneling. Alternatively, the radiation may be obtained by moving the crystal in and out of the field of a permanent magnet.
