Iqela lezazinzulu kwi-Massachusetts Institute of Technology kunye neStevens Institute of Technology eNew Jersey lenze iteknoloji yokushicilela ye-3D ephezulu kakhulu. Abashicileli be-3D abaqhelekileyo banokuprinta izinto ezincinci njenge-150 microns. Itekhnoloji ecetywayo eMIT iyakwazi ukuprinta into eyi-10 yemicrons ubukhulu. Ukuchaneka okunjalo akufuneki ukuba kusetyenziswe ngokubanzi kushicilelo lwe-3D, kodwa kuya kuba luncedo kakhulu kuphando lwe-biomedical kunye nonyango kwaye ithembisa impumelelo kwezi ndawo.
Inyani kukuba namhlanje, ngokwentelekiso, ii-substrates ezine-dimensional zisetyenziselwa ukukhulisa iinkcubeko zeeseli. Indlela kunye nendlela iikholoni zeeseli ezikhula ngayo kwii-substrates ezinjalo ubukhulu becala ngumcimbi wamabona-ndenzile. Ngaphantsi kweemeko ezinjalo, akunakwenzeka ukulawula ngokuchanekileyo imilo kunye nobukhulu bekholoni eyandisiweyo. Enye into yindlela entsha yokuvelisa i-substrate substrate. Ukwandisa isisombululo se-3D yoshicilelo kwisikali seseli sivula indlela yokudala i-cell cell okanye isakhiwo se-porous, imilo eya kuqinisekisa ngokuchanekileyo ubungakanani kunye nokubonakala kwekholoni yeseli ezayo. Kwaye ukulawula ifom kuya kugqiba ubukhulu becala iipropati zeeseli kunye nekholoni iyonke. Kutheni kukho iikoloni? Ukuba wenza i-substrate ngesimo sentliziyo, ilungu liya kukhula elibukeka njengentliziyo, kungekhona isibindi.
Masenze ugcino lokuba okwangoku asithethi ngamalungu akhulayo, nangona abaphandi beqaphela ukuba iiseli ze-stem zihlala ixesha elide kwiiseli ezenziwe ngeeseli ezinobungakanani be-micrometer kune-substrate eqhelekileyo. Ukuziphatha kwee-colonies zeeseli ezineempawu ezahlukileyo kwi-substrate entsha ene-dimensional-dimensional kufundwa ngoku. Uqwalaselo lubonisa ukuba iimolekyuli zeprotheyini zeeseli zenza ukunamathela okuthembekileyo kwindawo yokubambelela kwi-substrate lattice kunye nomnye komnye, ukuqinisekisa ukukhula kwekholoni kumthamo wemodeli ye-substrate.
Izazinzulu zakwazi njani ukunyusa isisombululo soshicilelo lwe-3D? Njengoko kuchaziwe kwinqaku lenzululwazi kwijenali Microsystems kunye neNanoengineering, itekhnoloji yokunyibilika kwe-electrowriting yanceda ukonyusa isisombululo. Ngokwesiqhelo, intsimi ye-electromagnetic eyomeleleyo yasetyenziswa phakathi kwentloko yoshicilelo yomshicileli we-3D kunye ne-substrate yokuprinta imodeli, eyanceda ukutyumza kwaye ngendlela ethile iqondise imathiriyeli etyhidiweyo ephuma kwimibhobho yentloko yoshicilelo. Ngelishwa, akukho zinkcukacha zinikiweyo.
