Applications of radioactive tracers and nanoparticles
Invited Lecture
Currently, enormous progress is being made in producing a great number of nanomaterials. However, in spite of hundreds of nano-products produced and currently available on the market a huge health and safety questions remain unsolved, and the assessment of possible health risks of nanoscale materials before they become ubiquitous in every aspects of life is necessary. In order to reach this...

Applications of radioactive tracers and nanoparticles
Invited Lecture
Attempts are being made to replace radiochemical neutron activation analysis (RNAA) by other analytical techniques capable of low-level element determination, such as various modes of atomic absorption spectrometry (AAS) for single-element determination, various modes of mass spectrometry, especially inductively coupled plasma mass spectrometry (ICP-MS) for multielemental analysis and/or by...

Invited Lecture
The contents of twelve trace elements in normal (n=37), benign hypertrophic (n=43) and cancerous tissues (n=60) of the human prostate gland were investigated by instrumental neutron activation (INAA) and by radionuclide-induced (109Cd) energy dispersive X-ray fluorescent (EDXRF) analysis. The contents of Ag, Co, Cr, Fe, Hg, Rb, Sb, Sc, Se, and Zn, and of Br, Fe, Rb, Sr, and Zn were measured by...

Applications of radioactive tracers and nanoparticles
Invited Lecture
Most metals and metalloids present in biological materials are bound to proteins where they have essential tasks as part of the catalytic centers of enzymes or as structural components. It has been estimated that in the biosphere a multitude of these compounds exists but so far relatively few of them have been detected. Since in most cases the presence of a metal or metalloid in a protein...

Applications of radioactive tracers and nanoparticles
Invited Lecture
High-energetic protons and secondary particles produce in interaction with matter – due to the broadness of the induced nuclear reactions – a big variety of radionuclides, with some of them being very rare, exotic, and, in several cases, difficult to be produced by complementary reactions. Depending on the nature of the activated material, valuable isotopes, interesting for scientific and...

Applications of radioactive tracers and nanoparticles
Invited Lecture
We have undertaken the design, synthesis, and testing of reusable mesoporous materials for actinide and lanthanide separation, sequestration, and sensing. An experimental-computational collaboration has yielded several materials with a high binding capacity for 239Pu: functionalized mesoporous silica, mesoporous carbon, and ferrihydrite. Advances have been made with all three types of...

Applications of radioactive tracers and nanoparticles
Oral Communications
Radioactive tracers provide a simple and effective tool for transport studies of nanoparticulate materials within environmental samples at laboratory scale. Compared to classical approaches radiolabelling of nanoparticles (NP) offers advantages in sensitivity and selectivity together with the possibility of in-situ imaging of transport phenomena. Particularly with regard to quantitative...

Bimetallic nanoparticles of Au with Ag, Cu, and Ir were synthesized by irradiating aqueous bimetallic ions with gamma radiation that generates hydrated electrons neutralizing the metal ions to a particle form. The bimetallic nanoparticles were coated with SiO2 making them chemically and physically stable when released into the environment and most of industrial processes for hydrodynamic...

The most practiced approach of drug delivery in cancer therapy over the last century has involved intravenous administration of cytotoxic chemotherapeutic or radionuclide-based nuclear medicine agents. Limited affinity of targeted chemotherapeutic agents or radiopharmaceuticals to tumor cites and also the vascular and interstitial transport barriers continue to pose vexing challenges in...
