Enye yezinkinga ezikhathaza kakhulu kunoma yimuphi umphakathi wanamuhla ilele ngqo esidingweni sokuqeda izifo ezithile izakhamizi eziningi ezibhekene nazo. Manje kubonakala sengathi sesiseduze kakhulu nokukwazi ukuqeda, ngokwesibonelo, ngesinye esivame kakhulu njengomdlavuza, isifo kungaqedwa ngale ndlela ngamahora angama-48 kuphela, noma okungenani yilokho okushiwo ngabaphenyi asebevele behlola lobu buchwepheshe obusha.
Ukuthola imininingwane ethe xaxa, ngikutshele ukuthi namuhla lolu phenyo olumangazayo lwenziwa ngokuhlanganyela ngabasebenzi abavela kuzo zombili I-Arizona State University njenge Isikhungo Sikazwelonke SeNanoscience Nobuchwepheshe baseChina. Njengoba ngishilo esigabeni esedlule, into ethakazelisa kakhulu ukuthi le ndlela entsha, equkethe umjovo, isivele ihlolwe ngempumelelo kuzo zombili amagundane nezingulube, ngakho isinyathelo esilandelayo ukuqala ukuhlola nabantu.
Ama-DNA nano-robots angabulala izicubu kubantu
Ngaphambi kokuqhubeka nokungena emininingwaneni eminingi, ngithanda ukukushiya nenkulumo ekhanyisela kakhulu mayelana nalokho okufeziwe ngalobu buchwepheshe obusha futhi obuvela ephepheni elishicilelwe yi obhekele ukuthuthukiswa kwephrojekthi:
Sisebenzisa amamodeli wegundane athwele isimila, sikhombisile ukuthi imijovo efakwa ngomjovo we-DNA nano-robots iletha i-thrombin ikakhulukazi emithanjeni yegazi ehambisana nesimila futhi idale i-intravascular thrombosis, okuholele kwi-tumor necrosis nasekuvimbeleni ukukhula.
Njengoba wazi impela, akusikho okokuqala ukuthi kuxoxwe ngokusetshenziswa kwama-nano-robots, empeleni akuyona inkambu entsha leyo, uma sikhuluma ngayo Ama-DNA nano-robots izinto ziguquka kakhulu njengoba singena emkhakheni wokuthi, nakuba unabalandeli abambalwa, iqiniso ukuthi singawuhlukanisa njengamuva nje. Umqondo okhona mayelana ne-DNA nano-robots ulele ekusetshenzisweni kokuthola i-DNA uqobo I-DNA iyazigoqa kube sengathi yibhola lephepha kuze kube, lapho kufika isikhathi, lingavuleka bese lithatha isinyathelo.
Ngokuyinhloko le ndlela entsha ehlongozwayo ukukwazi ukuhambisa noma yiluphi uhlobo lomuthi kumaseli athile futhi, uma sekutholakele ukuthi i-DNA isifinyelele ngempela esitokisini esifuna ukusinikeza umuthi hhayi omunye, iyawukhipha. Ukufeza lokhu iqembu belilokhu lisebenza ku ama-aptamers, ama-antibody amakhemikhali akhomba ngqo amaprotheni athile atholakala ezindaweni ezinamaseli ezinwele ngaphandle kokuhlasela empeleni amaseli aphilile.
Kuze kube manje ukuhlolwa okwenziwe kumagundane nezingulube zaselebhu kube yimpumelelo
Mhlawumbe ingxenye ethakazelisa kakhulu yale phrojekthi yonke ingatholakala esithembisweni esenziwe ngabaphenyi bayo lapho, ngokusobala futhi kucatshangelwa izivivinyo ezenziwe, kufinyelelwe ukuthi lawa ma-nano-robots ahlasela nje izicubuNgamanye amagama, le nqubo ayibangeli ukulimala kwezinye izitho zomzimba, enye yezinkinga ezinkulu zendlela yamanje yokwelapha.
Ngaphandle kokungabaza lokhu kungaba ukuthuthuka okuhle, ikakhulukazi uma kukhulunywa ngokufeza ukuqeda izinkinga ezingadalwa yizixazululo zamanje njengezikhathi zamakhemikhali okumele zonke iziguli ezinomdlavuza zibhekane nazo nokuthi, ngoba zinolaka kakhulu, zichitha izinto eziningi zisendleleni yokubulala amangqamuzana ezimila.
Njengoba abacwaningi abasebenza ekwakhiweni kwale ndlela beqinisekisa nsuku zonke, asisakwazi ukujabula kusukela lapho kuye kwenzeka kuphela ukufakazela ukubaluleka kwayo elabhorethriKusele ukuqala ukwenza izivivinyo nabantu futhi kuqinisekiswe ukusebenza kwayo ukuze, ngemuva kwakho konke lokhu (inqubo engathatha iminyaka eminingana) ukuyifinyelela emphakathini.
