Ngomzamo wokwenza ukuba ukuveliswa kwezinto eziphilayo kufikeleleke ngakumbi, abaphandi kwiYunivesithi yaseCalifornia, eBerkeley badibanisa i-2D bioprinting, ingalo yerobhothi yendibano ye-3D, kunye ne-flash frying ngendlela enokuthi ngenye imini ivumele ukuprintwa kwezicubu eziphilayo kunye nokuba. amalungu apheleleyo. Ngokuprinta amalungu kumaphepha amancinci eethishu, emva koko uwakhenkce kwaye uwabeke ngokulandelelana, itekhnoloji entsha iphucula ukusinda kweeseli zebhayoloji zombini ngexesha lokushicilela nangexesha lokugcinwa okulandelayo.
I-BioMaterials inamandla amakhulu amayeza exesha elizayo. Ukuprintwa kwe-3D kusetyenziswa iiseli zesilonda zesigulana kuya kunceda ukudala amalungu okufakelwa ahambelana ngokupheleleyo kwaye awayi kubangela ukwaliwa.
Ingxaki kukuba iindlela zangoku ze-bioprinting zicotha kwaye azinyuki kakuhle kakhulu kuba iiseli zinobunzima bokusinda kwinkqubo yoshicilelo ngaphandle kolawulo oluluqilima kakhulu lobushushu kunye nokusingqongileyo kwemichiza. Kwakhona, ubunzima obongezelelweyo bubekwe ngokugcinwa okuqhubekayo kunye nokuthuthwa kweendwangu eziprintiweyo.
Ukoyisa ezi ngxaki, iqela laseBerkeley lagqiba kwelokuba lingqamanise inkqubo yoshicilelo kwaye liyahlulahlule ngokwezigaba ezilandelelanayo. Oko kukuthi, endaweni yokuprinta i-organ yonke ngaxeshanye, izicubu ziprintwa ngaxeshanye kwi-XNUMXD layers, ezithi zibekwe phantsi ngengalo yerobhothi ukwenza ulwakhiwo lokugqibela lwe-XNUMXD.
Le ndlela sele ikhawulezisa inkqubo, kodwa ukunciphisa ukufa kweeseli, iileya zifakwe ngokukhawuleza kwibhafu ye-cryogenic ukuze zikhenkce. Ngokutsho kweqela, oku kwandisa kakhulu iimeko zokusinda kwezinto eziprintiweyo ngexesha lokugcinwa kunye nokuthutha.
"Okwangoku, i-bioprinting isetyenziswa ikakhulu ukwenza umthamo omncinci wezicubu," utshilo u-Boris Rubinsky, unjingalwazi wobunjineli boomatshini. βIngxaki nge-3D bioprinting kukuba yinkqubo ecothayo kakhulu, ngoko ke awuzukwazi ukuprinta nantoni na enkulu kuba izinto zebhayoloji ziyakufa xa ugqibile. Enye yezinto zethu ezintsha kukuba sikhenkceza izicubu njengoko siziprinta, ngoko ke izinto zebhayoloji ziyagcinwa. "
Iqela liyavuma ukuba le ndlela yokushicilela i-3D ayintsha, kodwa ukusetyenziswa kwayo kwi-biomaterials yinto entsha. Oku kuvumela ukuba amaleko ashicilelwe kwindawo enye aze ahanjiswe kwenye ukuze adityaniswe.
Ukongeza ekudaleni izicubu kunye namalungu, obu buchule bunezinye izinto ezisetyenziswayo, ezinje ngokuveliswa kokutya okukhenkcezisiweyo kwinqanaba lemizi-mveliso.
