PROCESS OF PREPARING POLYMERIC NANOPARTICLES THAT CHELATE RADIOACTIVE ISOTOPES AND HAVE A SURFACE MODIFIED WITH SPECIFIC MOLECULES TARGETING THE PSMA RECEPTOR AND THEIR USE

摘要

Process for preparation of polymeric nanoparticles that chelate radioactive isotopes and have their surface modified with specific molecules targeting PSMA receptor on the surface of cancer cells, with a targeting agent modified by a linker molecule attaching to free aldehyde groups present in the dextran chain. Polymeric nanoparticles that chelate radioactive isotopes synthesised according to the claimed process for use in therapy and diagnostics of prostate cancer and metastatic cancer cells as well as other affected cells for which the nanoparticles show the affinity.
