A method of forming an injectable radioactive composition, the method comprising the steps of: (a) depositing a solid form of technetium onto a carbon crucible; (b) preheating the solid form of technetium to remove any carrier; (c) plasma ablating the technetium and portions of the carbon crucible; (d) allowing the carbon and technetium metal to co-condense from the gas phase to produce a nanoparticle composite aerosol in an inert gas; (e) dispersing the nanoparticle composite in water containing a low concentration of surfactant using an electrostatic precipitator; (f) size fractionating the nanoparticle dispersion by filtration with hydrophilic membranes of known pore size.

Method of forming an injectable radioactive composition of a carbon encapsulated radioactive particulate

A method for forming an inhalable isotope compound suitable for use in patient medical diagnosis, the method comprising the steps of: (a) electrolytic loading of a carbon crucible with the isotope; (b) sublimating any isotope carrier in the crucible; (c) ablating the isotope in a carbon crucible, forming an ablation aerosol; (d) directly delivering the aerosol for immediate use by a patient. The isotope can comprise technetium.

Process for the production of a radioactive aerosol

A method for the detection of fibrin in a source, in particular the in vivo detection of a fibrin in a patient, the method comprising supplying to the source or patient an amount of a detectable reagent comprising a plurality of discrete particles, each of the particles comprising a plurality of layers of carbon and being capable of binding to fibrin; and detecting the presence of the particles in the source. The particles may also comprise a detectable marker encased in said plurality of layers of carbon, the presence of said marker being capable of detection in said source.
