Izazinzulu ze-NRNU MEPhI zifunde indlela yokusebenzisa i-plasma ebandayo kwi-biomedicine. Abaphandi be-NRNU MEPhI, kunye nabalingane babo abavela kwamanye amaziko esayensi, baphanda ukuba kunokwenzeka ukusebenzisa i-plasma ebandayo ukuxilonga nokunyanga izifo zebhaktiriya kunye nentsholongwane kunye nokuphiliswa kwamanxeba. Olu phuhliso luya kuba sisiseko sokwenziwa kwezixhobo zonyango ezintsha zobugcisa obuphezulu. Ii-plasma ezibandayo ziingqokelela okanye ukuhamba kwee-particles ezitshajiweyo ezihlala zingathathi cala ngombane kwaye zinobushushu obuphantsi be-atomic kunye ne-ionic, umzekelo, kufutshane nobushushu begumbi. Okwangoku, oko kubizwa ngokuba bubushushu be-electron, obuhambelana nenqanaba lokuvuselela okanye i-ionization yeentlobo ze-plasma, bunokufikelela kumawaka aliqela eedigri.
Isiphumo seplasma ebandayo singasetyenziswa kwezonyango – njengeyeza lokuthambisa, sikhuselekile emzimbeni womntu. Uqaphele ukuba ukuba kuyimfuneko, iplasma ebandayo inokuvelisa i-oxidation ebalulekileyo yendawo, efana ne-cauterization, kwaye kwezinye iindlela, inokubangela iindlela zokuphilisa ezivuselelayo. Ii-radicals zasimahla zeekhemikhali zingasetyenziselwa ukusebenza ngokuthe ngqo kwiindawo ezivulekileyo zesikhumba kunye namanxeba, ngokusebenzisa iijethi zeplasma eziveliswa ziityhubhu zeplasma ezincinci ezenziwe ngobunjineli, okanye ngokungathanga ngqo ziimolekyuli zokusingqongileyo ezinomdla ezifana nomoya. Okwangoku, itotshi yeplasma ekuqaleni isebenzisa ukuhamba okubuthathaka kwegesi engasebenziyo ekhuselekileyo ngokupheleleyo –i-helium or i-argon, kwaye amandla obushushu avelisiweyo anokulawulwa ukusuka kwiyunithi enye ukuya kumashumi eewatts.
Lo msebenzi usebenzise iplasma yoxinzelelo lomoya oluvulekileyo, umthombo ophuhliswe ngawo izazinzulu kwiminyaka yakutshanje. Umsinga wegesi oqhubekayo kuxinzelelo lomoya unokufakwa kwi-ionized ngelixa uqinisekisa ukuba ususwa kumgama ofunekayo, ukusuka kwiimilimitha ezimbalwa ukuya kwishumi leesentimitha, ukuze kuzise umthamo wezinto ongathathi cala kwi-ionized kubunzulu obufunekayo kwindawo ethile ekujoliswe kuyo (umz., indawo yesikhumba sesigulana).
UViktor Tymoshenko ugxininise wathi: “Sisebenzisai-heliumnjengegesi ephambili, esivumela ukuba sinciphise iinkqubo zokuxinana ezingafunekiyo. Ngokungafaniyo nophuhliso oluninzi olufanayo eRashiya nakwamanye amazwe, kwiitotshi zeplasma esizisebenzisayo, ukuveliswa kweplasma ye-helium ebandayo akuphelekwanga kukwenziwa kwe-ozone, kodwa kwangaxeshanye kubonelela ngesiphumo sonyango esicacileyo nesilawulekayo.” Besebenzisa le ndlela intsha, izazinzulu zinethemba lokunyanga izifo ezibangelwa ziintsholongwane. Ngokutsho kwabo, unyango lweplasma ebandayo lunokususa ngokulula ungcoliseko lwentsholongwane kwaye lukhawulezise ukuphiliswa kwamanxeba. Kuthenjwa ukuba kwixesha elizayo, ngoncedo lweendlela ezintsha, kuya kwenzeka ukunyanga izifo zethumba. “Namhlanje sithetha kuphela ngesiphumo esingaphantsi kakhulu, malunga nokusetyenziswa kwesikhumba. Kwixesha elizayo, ubuchwepheshe bunokuphuhliswa ukuze bungene nzulu emzimbeni, umzekelo ngenkqubo yokuphefumla. Okwangoku, senza uvavanyo lwe-in vitro, xa iplasma yethu xa ijethi idibana ngokuthe ngqo nolwelo oluncinci okanye ezinye izinto zebhayoloji zemodeli,” utshilo inkokheli yeqela lezenzululwazi.
