Empilweni yansuku zonke, amathangi e-nitrogen angase angabonakali njengezinto ezivamile. Ngakho-ke, kuziphi izimboni nezindawo lapho kusetshenziswa khona amathangi e-nitrogen aqukethe uketshezi? Iqiniso liwukuthi izimo zokusetshenziswa kwamathangi e-nitrogen aqukethe uketshezi aziyona imfihlakalo. Ngokuyinhloko asetshenziselwa ukulondolozwa nokuthuthwa kwesikhathi eside kwezinhlobo zezinto eziphilayo, njengezibonelo zegazi, amaseli, isidoda, izicubu, imijovo, amagciwane, kanye nesikhumba esivela ezilwaneni, ezitshalweni, noma kubantu, amathangi e-nitrogen aqukethe uketshezi athola indawo yawo kwezolimo, ukufuya izilwane, ukunakekelwa kwempilo, imithi, ukudla, ucwaningo, kanye neminye imikhakha.
Emkhakheni wezolimo, amathangi e-nitrogen ewuketshezi adlala indima ebalulekile emisebenzini efana nokuqandisa isidoda semfuyo ukuze sizale, ukugcina isikhathi eside ama-embryo ezilwane kanye nembewu yezitshalo. Izikhungo zemboni yezilwane, okuhlanganisa nezikhungo zezwe kanye nezifunda zokunakekela izilwane, zisebenzisa amathangi e-nitrogen ewuketshezi ukugcina izinto zofuzo ezifana nesidoda kanye nama-embryo avela ezingulubeni, ezinkomeni nasezinkukhu. Ekulimeni kwezitshalo, la matangi asetshenziswa ezindaweni zokugcina izinsiza zezolimo zokugcina imbewu nokuningi.
Ngaphakathi kwemboni yezokunakekelwa kwempilo, amathangi e-nitrogen ewuketshezi abalulekile kuma-biobank ezibhedlela, ama-laboratories aphakathi, kanye nama-laboratories ahlukahlukene omnyango, okuhlanganisa i-oncology, i-pathology, imithi yokuzala, kanye nokuxilonga. Asetshenziswa ukulondolozwa nokwelashwa kwezitho zomzimba, isikhumba, amasampula egazi, amaseli, amagciwane, kanye nokufakelwa isidoda okwenziwe ngokwenziwa. Ukuba khona kwamathangi e-nitrogen ewuketshezi kuqhubeka nokuthuthukisa i-cryomedicine yezokwelapha.
Embonini yezemithi kanye nokudla, amathangi e-nitrogen ewuketshezi asetshenziselwa ukuqandisa kakhulu nokulondoloza amaseli nama-specimens, ukukhipha izinto ezishisayo eziphansi, kanye nokugcina ukudla kwasolwandle okuseqophelweni eliphezulu. Amanye asetshenziswa ngisho nasekudalweni kwe-ayisikhilimu ye-nitrogen ewuketshezi.
Ocwaningweni nakweminye imikhakha, amathangi e-nitrogen ewuketshezi ahlinzeka ngamasu okushisa okuphansi, i-ecology eshisa kakhulu, ucwaningo lwe-superconductivity eshisa kakhulu, izinhlelo zelebhu, kanye nezindawo zokugcina i-germplasm. Isibonelo, ohlelweni locwaningo lwezolimo kanye nendawo yokugcina izinsiza zezitshalo ezihlobene nezitshalo, amaseli ezitshalo noma izicubu, ngemva kokwelashwa kokungaqandisi, kudingeka agcinwe endaweni ene-nitrogen ewuketshezi.

Ngokusebenzisa amasu okugcina amanzi, ukubeka amaseli ku--196°C i-nitrogen ewuketshezi ukuze kugcinwe izinga lokushisa eliphansi, lawa matanki enza amaseli akwazi ukumisa okwesikhashana isimo sawo sokukhula, alondoloze izici zawo futhi anikele kakhulu ekusheshiseni ukuhunyushwa kwemiphumela yocwaningo. Kuzo zonke lezi zindawo ezahlukahlukene, izinhlobo ezahlukene zamatanki e-nitrogen ewuketshezi zikhanya kakhulu, ziqinisekisa ukuphepha kwamasampula ebhayoloji.
