Esinye sezifo ezibuhlungu kakhulu ukuba abantu banokubandezeleka sinento yokwenza nayo ukonakala kwentlala ikhona kumalungu ethu, imeko enokuba nzima kakhulu ukuyilungisa kuphela ngotyando. Ngenxa yoku kunye nokuzama ukufumana isisombululo esinokubakho ngakumbi kwaye sinomdla, ukusuka IYunivesithi yasePennsylvania State, namhlanje sinikwe ukufumanisa ukuba kungafakwa njani ukufakelwa kwe-cartilage yokufakelwa kusetyenziswa ukuprinta kwe-3D.
Kude kube ngoku, inyani yokudala intlala yokufakelwa yayineengxaki ezininzi, hayi kuba sijamelene nenkqubo enzima kwaye ibiza kakhulu kwinqanaba lezoqoqosho, kodwa kungenxa yokudala intlala yokufakelwa zonke iindlela zazisekwe kwimanyano yothotho ihydrogel nanotubes. Eyona nto ibisenziwa kukuba intlala ayivumanga ukukhula okuqhelekileyo yomntu.
Ukuya kwiinkcukacha ezithe kratya kwaye ngokwezifundo ezibhekisa kule klasi ye-cartilage, kubonakala ukuba ukusetyenziswa kwayo kuyenzile inqanda ukukhula okuqhelekileyo kweeseli yomguli. Ngokubhekisele kuvavanyo olwenziwa kwiYunivesithi yasePennsylvania State, kubonakala ngoku ukuba izicwili zinokwenziwa kwinqanaba elikhulu ngaphandle kwesidingo, njengoko besitsho, ukusebenzisa naluphi na uhlobo lwe «ukutyabeka«.
Ukwenza esi sizukulwana sitsha se-cartilage yokufakelwa, kulandelwa inkqubo yamanyathelo amabini. Okokuqala, uthotho lwe iityhubhu ezincinci, 3 ukuya ku-5 ngekhulu le-intshi nge-intshi, ukusuka alginate, isicatshulwa solwandle. Okwangoku, iiseli ze-cartilage ziqala ukuhlangana ngaphandle kokubambelela kwi-alginate. Emva kweentsuku ezisixhenxe, ezi seli ziye zaphalaza ukuhamba okushiyekileyo imicu emincinci yentlala. Le micu okanye imisonto zezona zisetyenziselwa ukwakha izinto kulwakhiwo olufunayo kusetyenziswa umshicileli we-3D.
Isiphumo senkqubela yokufakelwa kabani ulwakhiwo lufana kakhulu nentaka yenkomo yendalo nangona, ngelishwa, ayinamandla kangako. Nangona kunjalo, inyani kukuba ngovavanyo olwenziwe, lomelele kunentlala yokufakelwa eyenziwe ngehydrogel. Ngokwenxalenye yeqela eliphethe le projekthi, kukholelwa ukuba amandla ayo anokukhula ukuba asetyenziswa kwizigulana zokwenyani kuba uxinzelelo olwenziwe ngamalungu luya kuphucula iipropathi zalo.
