An expected increase in the efficiency of antiproton cancer therapy with the use of gold nanoparticles. - GreenMedInfo Summary

The use of gold nanoparticles in antiproton cancer therapy is proposed. The energy transferred to gold by particles bombarding a tumor and arising in it is considered as one of the parameters determining the biological effect of gold in proton and antiproton cancer therapies. An example corresponding to the assumption about the importance of this parameter is analyzed. It is shown that the energy transferred to gold by products of annihilation of stopped antiprotons in soft biological tissues can exceed that transferred by antiprotons before their annihilation.
