| Outline of Final Research Achievements |
We evaluated the feasibility of hyaluronic acid (HA) to be used as targeting agent for boron compounds, including gold nanoparticles (GNPs), for combined glioma radiotherapy. Boron-HA (BHA) showed different accumulation in tumor and healthy tissues in rats. Security of BHA bonds might be necessary to increase the stability of the compound. We evaluated the efficacy of boron-neutron capture therapy using boron-phenylalanine (BPA) with GNPs used for absorbed neutron dose estimation at the accelerator-based neutron source. Our method allows to determine the absorbed neutron dose using combined boron compounds containing high-Z element and can be implemented in isotope scanning and positron emission tomography (PET).
