Final report

  
Results in Hungarian
A kutatás új szempontokat tárt fel a fullerének oldhatóságáról, szerkezeti vonatkozásairól, amelyek biokompatibilitásuk, toxicitásuk (ezek pillanatnyilag folyamatban vannak) vizsgálatát teszik lehetővé. A szerkezeti tisztázást Raman és nukleáris reaktorban való mérésekkel végeztük. Ez utóbbi mérésekkel mutattuk ki, hogy a szén nanocsövek nyomelemszennyezése a valószínű oka a világszerte folyó nanocsőelektronikai eredmények reprodukálhatatlanságának. A fullerének vízben teljesen oldhatatlanok és ez jelentős akadály toxicitásuk és biokompatibilitásuk vizsgálatánál. Eddig kb. 150 szerves oldószert vizsgáltak meg a fullerének oldhatóságának szempontjából és ezek közül egyesek mint pld. a toluol, nitrobenzol, széndiszulfid megfelelőknek bizonyultak, azaz elfogadhatóan oldották a fulleréneket. Sajnos ezek alkalmazása élő szervezetekben lehetetlen. E kérdés megoldását jelentették azok a vizsgálatok és eredmények, amelyekben világviszonylatban első ízben bizonyítottuk, hogy növényi olajok, mint pld. az olívaolaj, a napraforgóolaj, a tökmagolaj, a repceolaj elfogadhatóan oldják a C60 és C70 fulleréneket, ezáltal lehetőséget nyújtva biológiai, biokémiai és élő szervezetben való kísérletek végzésére. Az oldódás mechanizmusára vonatkozóan annak hőmérséklet függésének mérésével bizonyítottuk, hogy az oldódás exotermikus folyamatként játszódik le.
Results in English
The research has revealed new vistas on the solubility of fullerenes and their structural aspects which contributed to the possibility of studies of their biocompatibility and toxicity (our measurements on this later aspects are on their way). The structural examinations were using Raman spectrometry. Neutron irradiation in a nuclear reactor using neutron activation analysis has shown that the trace elements determined in carbon nanotubes are the possible ground of the worldwide irreproducibility of nanoelectronics with nanotubes.
