Enye yezona zinto zixhalabisayo kulo naluphi na uluntu lwangoku zilele ngqo kwisidingo sokuphelisa izifo ezithile abajamelana nazo uninzi lwabemi. Ngoku kubonakala ngathi sikufutshane kakhulu ekubeni sikwazi ukuphela, umzekelo, ngesinye sezona zixhaphakileyo njengomhlaza, isifo inokupheliswa ngobu buchule kwiiyure nje ezingama-48, okanye ubuncinci yiloo nto abaphandi abasele bevavanya le teknoloji intsha bathi.
Ukuya kwiinkcukacha ezithe kratya, xelela ukuba namhlanje olu phando lumangalisayo lwenziwa ngokudibeneyo ngabasebenzi abasuka kuzo zombini KwiYunivesithi yaseArizona njenge Iziko leLizwe leNanoscience kunye neTekhnoloji ye China. Njengoko benditshilo kumhlathi odlulileyo, eyona nto inomdla kukuba le ndlela intsha, enesitofu, sele ivavanywe ngempumelelo kwiimpuku nakwiihagu, ke inyathelo elilandelayo kukuqala ukuvavanya nabantu.
I-DNA nano-robots inokubulala amathumba ebantwini
Phambi kokuba ndiqhubeke kwaye ndingene kwiinkcukacha ezithe vetshe, ndingathanda ukukushiya nebinzana elisikhanyisela kakhulu malunga noko kufezekisiweyo ngale teknoloji intsha kwaye ivela kwiphepha elipapashwe yi inoxanduva lokuphuhliswa kweprojekthi:
Sisebenzisa imodeli yegundane ethwele imithambo, sabonisa ukuba ngenaliti efakwe ngaphakathi kwi-DNA nano-robots ihambisa i-thrombin ngokuthe ngqo kwimithambo yegazi enxulumene nethumba kunye ne-intravascular thrombosis, ekhokelela kwi-tumor necrosis kunye nokuthintela ukukhula.
Njengoko uyazi ngokuqinisekileyo, ayiloxesha lokuqala ukuba kusetyenziswe i-nano-robots malunga nayo, ayisiyiyo intsimi entsha nangona, ukuba sithetha ngayo I-DNA nano-robots izinto zitshintsha kakhulu xa singena kuqeqesho, nangona lunabalandeli abambalwa, inyani kukuba sinako ukuluhlela njengolu lwamva nje. Umbono okhoyo malunga ne-DNA nano-robots ulele kuluncedo lokufumana iDNA uqobo I-DNA isonga ngaphezulu kwayo ngokungathi yibhola yephepha de kube, xa kufika ixesha, inokuvela kwaye yenze isenzo.
Ngokusisiseko le ndlela intsha icebisa ngayo kukukwazi ukuhambisa naluphi na uhlobo lweziyobisi kwiiseli ezithile kwaye, yakuba ifunyenwe ukuba iDNA ifikelele kwiseli esifuna ukubonelela ngayo iyeza hayi enye, iyayikhupha. Ukufezekisa oku iqela belisebenza kwi aptamers, ii-antibodies zemichiza ezijolise ngokukodwa kwiiproteni ezithile ezigcweleyo kwiindawo zeeseli zethumba ngaphandle kokuhlasela iiseli ezisempilweni.
Ukuza kuthi ga ngoku kuvavanyo olwenziwe kwiimpuku zaselebhu kunye neehagu lube yimpumelelo
Elona candelo linomdla kule projekthi iphela lingafunyanwa kwisithembiso esenziwe ngabaphandi bayo apho, ngokucacileyo kwaye kuthathelwa ingqalelo iimvavanyo ezenziweyo, kufezekisiwe ezi nano-robots zihlasela nje amathumbaNgamanye amagama, obu buchule abubangeli monakalo kwamanye amalungu omzimba, enye yeengxaki ezinkulu zendlela yokunyanga yangoku.
Ngaphandle kwamathandabuzo, oku kunokuba yinkqubela phambili enkulu, ngakumbi xa kufikwa ekuphumezeni ukuphelisa iingxaki ezinokubangelwa zizisombululo zangoku ezinje ngeeseshini ze-chemotherapy ekufuneka zijongane nazo zonke izigulana ezinomhlaza kwaye, ngenxa yokuba zinoburhalarhume, zitshabalalisa izinto ezininzi zisendleleni yokubulala iiseli zethumba.
Njengoko abaphandi abasebenza kuphuhliso lobu buchule beqinisekisa yonke imihla, asinako ukuvuya ukusukela oko ikwazile ukungqina ixabiso layo elebhu kuphelaKuhleli ukuqala ukwenza uvavanyo ebantwini kunye nokuqinisekisa ukusebenza kwayo ngokulandelelana, emva kwayo yonke le nto (inkqubo enokuthatha iminyaka eliqela) ukuyifikelela eluntwini.
