Radioisotopes provide both diagnostic tools and therapeutic treatments for cancer and other diseases. In the US, millions of radioisotope doses are given to patients per year. Radiopharmaceutical generators are widely used to provide such short-lived medical radioisotopes in a clinical setting. These generators work by exploiting chemical differences in a parent/daughter isotope relationship. Actinium-225 (half-life 10 d) is used to provide clinically useful amounts of daughter isotopes 213Bi (46 m). An integrated millifluidic 225Ac/213Bi radiopharmaceutical generator device was engineered to produce 213Bi labeled biomolecules. Using recent LANL successes in additive manufacturing of small-scale fluidic devices, a disposable device was developed that integrates three steps for the production of 213Bi labeled antibodies: 1) 213Bi separation from 225Ac parent, 2) 213Bi antibody labeling, and 3) purification of the labelled antibody.
