Enkosi ngomsebenzi weqela labaphandi kunye nososayensi abavela IZiko le-ARC lokuGqwesa kwiNzululwazi yezixhobo kunye Isibhedlele saseSan Vicente, eMelbourne (Australia), safumana iprojekthi eyabhaptizwa ngegama lika I-Biopen apho kuye kwakho khona ukwenza usiba lokushicilela olunamandla okushicilela iiseli zesitampu ze-3D ngexesha lokwenyani, ngaphandle kwamathandabuzo inyathelo eliphambili elinokusebenza, umzekelo, ukulungisa intlala kunye namathambo ngexesha lokungenelela kotyando.
Ukuze i-Biopen ibenakho ukusebenza ngeeseli ezinesiqu ngexesha lokwenyani, elinye lamanyathelo okuqala ekufuneka ethathiwe yayikukukhulisa uhlobo lwe-hydrogel bio-ink enokuthi ihambise kwaye ixhase iiseli zabantu. Emva koku, indlela yokufezekisa ukukhanya okwaziyo ukuqinisa i-inki yafundwa ngayo ukwenza ipeni yebhola, njengoko kunjalo, ikwazi ukubonelela isantya sokusinda kweseli yamkelekile, kwimeko yeBiopen, ebekwe ngaphezulu kwe-97%.
I-Biopen, usiba lokuprinta olunokwazi ukusebenza ngeeseli ezinesiqu ngexesha lokwenyani
Indlela yokusebenza kwale nkqubo ilula kakhulu, njengoko abaphuhlisi bayo bechaza, usiba lufaka into eneselfowuni kwindawo eyonakeleyo ye-cartilaginous. Iiseli zeziqu eziqulethwe kule khompawundi ziya kuzala kwakhona xa zikhutshwa, zisenza indawo yethambo elonakeleyo ikhule. Ukuba yipeni ngokoqobo, kuvumela ugqirha a ulawulo olungazange lubonwe ekuveliseni izicwili ezonakeleyo.
Ngokutsho UPeter choong, UMlawuli we-Orthopedics kwisibhedlele saseSan Vicente:
Ukuphuhliswa kolu hlobo lwetekhnoloji kunokwenzeka kuphela kunxibelelwano phakathi kwezenzululwazi kunye neeklinikhi: le yokugqibela ichonga ingxaki kunye noososayensi ukuze benze isisombululo.
Iprojekthi yepeni ibonakalisa imiceli mngeni kunye namathuba kuphando oluninzi lwezifundo. Xa sisenza ngcono, sinokwenza inkqubela phambili engaqhelekanga ngesantya esikhawulezayo.
Enkosi ku-Biopen ugqirha wotyando unegunya elingazange libonwe kunyango lwe-cartilage, ekwaziyo ukugcwalisa ukulinganisa izicwili eziyimfuneko.
