Ososayensi be-NRNU MEPhI bafunde indlela yokusebenzisa i-plasma ebandayo kwezokwelapha nge-biomedicine. Abacwaningi be-NRNU MEPhI, kanye nozakwabo abavela kwezinye izikhungo zesayensi, baphenya ukuthi kungenzeka yini ukusebenzisa i-plasma ebandayo ekuxilongweni nasekulapheni izifo zamagciwane kanye negciwane kanye nokuphulukiswa kwamanxeba. Lokhu kuthuthukiswa kuzoba yisisekelo sokudalwa kwamadivayisi ezokwelapha asezingeni eliphezulu. Ama-plasma abandayo ayiqoqo noma ukugeleza kwezinhlayiya ezishajayo ngokuvamile ezingakhethi ngogesi futhi ezinamazinga okushisa aphansi e-athomu kanye ne-ionic, isibonelo, eduze nokushisa kwegumbi. Okwamanje, izinga lokushisa elibizwa ngokuthi i-electron, elihambisana nezinga lokuvuselela noma i-ionization yezinhlobo ze-plasma, lingafinyelela ama-degree ayizinkulungwane eziningana.
Umphumela we-plasma ebandayo ungasetshenziswa kwezokwelapha - njenge-ejenti yokwelapha, iphephile emzimbeni womuntu. Uqaphele ukuthi uma kudingeka, i-plasma ebandayo ingakhiqiza i-oxidation ebaluleke kakhulu yendawo, njenge-cauterization, futhi kwezinye izindlela, ingabangela izindlela zokwelapha ezivuselelayo. Ama-radicals wamahhala wamakhemikhali angasetshenziswa ukusebenza ngqo ezindaweni ezivulekile zesikhumba nasemanxebeni, ngokusebenzisa ama-jet e-plasma akhiqizwa ngamashubhu e-plasma ahlanganisiwe, noma ngokungaqondile ngama-molecule emvelo ajabulisayo njengomoya. Okwamanje, ithoshi le-plasma ekuqaleni lisebenzisa ukugeleza okubuthakathaka kwegesi engasebenzi kahle ephephile ngokuphelele -i-helium or i-argon, futhi amandla okushisa akhiqizwayo angalawulwa kusukela kuyunithi eyodwa kuya kumashumi ama-watts.
Lo msebenzi usebenzise i-plasma yomfutho womoya ovulekile, umthombo ososayensi abebelokhu bewuthuthukisa ngenkuthalo eminyakeni yamuva nje. Umfudlana wegesi oqhubekayo ekucindezelweni komoya ungafakwa i-ionized ngenkathi kuqinisekiswa ukuthi ususwa ebangeni elidingekayo, kusukela kumamilimitha ambalwa kuya kwamashumi amasentimitha, ukuze kulethwe ivolumu yento engathathi hlangothi efakwe i-ionized ekujuleni okudingekayo endaweni ethile eqondiwe (isb., indawo yesikhumba sesiguli).
UViktor Tymoshenko wagcizelela: “Sisebenzisai-heliumnjengegesi eyinhloko, esivumela ukunciphisa izinqubo zokuxiliswa ezingadingeki. Ngokungafani nentuthuko eziningi ezifanayo eRussia nakwamanye amazwe, ezibanini ze-plasma esizisebenzisayo, ukukhiqizwa kwe-plasma ye-helium ebandayo akuhambisani nokwakheka kwe-ozone, kodwa ngesikhathi esifanayo kunikeza umphumela wokwelapha ocacile nolawulekayo.” Besebenzisa le ndlela entsha, ososayensi banethemba lokwelapha izifo ezibangelwa amagciwane ngokuyinhloko. Ngokusho kwabo, ukwelashwa nge-plasma ebandayo kungasusa kalula ukungcola kwamagciwane futhi kusheshise ukuphulukiswa kwamanxeba. Kuthenjwa ukuthi esikhathini esizayo, ngosizo lwezindlela ezintsha, kuzokwenzeka ukwelapha izifo zesimila. “Namuhla sikhuluma ngomphumela ongaphansi kakhulu, mayelana nokusetshenziswa kwangaphandle. Esikhathini esizayo, ubuchwepheshe bungathuthukiswa ukuze bungene bujule emzimbeni, isibonelo ngokusebenzisa uhlelo lokuphefumula. Kuze kube manje, senza izivivinyo ze-in vitro, lapho i-plasma yethu lapho indiza ixhumana ngqo nenani elincane loketshezi noma ezinye izinto eziphilayo eziyimodeli,” kusho umholi weqembu lesayensi.
