Ososayensi be-NRNU MEPhI bafunde indlela yokusebenzisa i-plasma ebandayo ku-biomedicine Abacwaningi be-NRNU MEPhI, kanye nozakwabo abavela kwezinye izikhungo zesayensi, baphenya ukuthi kungenzeka yini ukusebenzisa i-plasma ebandayo ekuxilongeni nasekwelapheni izifo ezibangelwa amagciwane kanye negciwane kanye nokuphulukiswa kwesilonda.Lokhu kuthuthukiswa kuzoba yisisekelo sokwakhiwa kwemishini yezokwelapha enobuchwepheshe obuphezulu.Ama-plasma abandayo amaqoqo noma ukugeleza kwezinhlayiya ezishajiwe ngokuvamile ezingathathi hlangothi ngogesi futhi ezinamazinga okushisa aphansi e-athomu ne-ionic, isibonelo, eduze nezinga lokushisa legumbi.Phakathi naleso sikhathi, okubizwa ngokuthi izinga lokushisa kwe-electron, elihambisana nezinga lokuvusa noma i-ionization yezinhlobo ze-plasma, lingafinyelela amadigri ayizinkulungwane ezimbalwa.
Umphumela we-plasma ebandayo ungasetshenziswa kwezokwelapha - njenge-ejenti ye-topical, iphephile ngokuqhathaniswa nomzimba womuntu.Waphawula ukuthi uma kunesidingo, i-plasma ebandayo ingakhiqiza i-oxidation yendawo ebaluleke kakhulu, njenge-cauterization, futhi kwezinye izindlela, ingabangela izindlela zokuphulukisa zokubuyisela.Ama-radicals angenamakhemikhali angasetshenziswa ukusebenza ngokuqondile endaweni evulekile yesikhumba kanye namanxeba, ngokusebenzisa amajethi e-plasma akhiqizwe amashubhu acwecwe e-plasma, noma ngokungaqondile ama-molecule emvelo ajabulisayo njengomoya.Ngaleso sikhathi, ithoshi le-plasma ekuqaleni lisebenzisa ukugeleza okubuthakathaka kwegesi ye-inert ephephe ngokuphelele -i-helium or i-argon, futhi amandla ashisayo akhiqizwayo angalawulwa ukusuka kuyunithi eyodwa ukuya kumashumi ama-watts.
Umsebenzi wasebenzisa i-plasma yokucindezela komkhathi evulekile, umthombo wayo ososayensi abebewuthuthukisa ngenkuthalo eminyakeni yamuva.Umfudlana wegesi oqhubekayo ngomfutho womkhathi ungenziwa i-ioni ngenkathi uqinisekisa ukuthi iyasuswa iye ebangeni elidingekayo, ukusuka kumamilimitha ambalwa ukuya emashumini amasentimitha, ukuletha umthamo we-ionized neutral wendaba ekujuleni okudingekayo endaweni ethile okuhlosiwe (isb. indawo yesikhumba yesiguli).
UViktor Tymoshenko wagcizelela: “Sisebenzisai-heliumnjengegesi eyinhloko, esivumela ukuba sinciphise izinqubo ze-oxidation ezingadingeki.Ngokungafani nentuthuko eminingi efanayo eRussia nakwamanye amazwe, emathoshi eplasma esiwasebenzisayo , ukukhiqizwa kweplasma ebandayo ye-helium akuphelezelwa ukwakheka kwe-ozone, kodwa ngesikhathi esifanayo kunikeza umphumela wokwelapha ocacile nolawulekayo.”Besebenzisa le ndlela entsha, ososayensi banethemba lokwelapha izifo ezibangelwa amagciwane ngokuyinhloko.Ngokusho kwabo, ukwelashwa kwe-plasma ebandayo nakho kungasusa kalula ukungcoliswa kwegciwane futhi kusheshise ukuphulukiswa kwesilonda.Kuthenjwa ukuthi esikhathini esizayo, ngosizo lwezindlela ezintsha, kuzokwazi ukwelapha izifo zesimila.“Namuhla sikhuluma nje ngomphumela ongemuhle kakhulu, mayelana nokusetshenziswa kwezihloko.Ngokuzayo, ubuchwepheshe bungathuthukiswa ukuze bungene bujule emzimbeni, isibonelo ngohlelo lokuphefumula.Kuze kube manje, senza izivivinyo ze-in vitro, lapho i-plasma yethu lapho indiza ihlangana ngokuqondile nenani elincane loketshezi noma ezinye izinto eziphilayo eziyimodeli,” kusho umholi weqembu lesayensi.
