Asayansi yunive yunive yunive yuniveur Buffalo ku New York adapanga njira yatsopano yomwe imawalola kugwiritsa ntchito zida za 3d kuti zizipanga zinthu za ma hydrogel omwe ali ndi ma cell. Ofufuzawo akuyembekeza kuti njira zawo zitha kugwiritsidwa ntchito mtsogolo chifukwa cha kusindikiza kwa zaka 3.
Zambiri za izi zidafalitsidwa m'magazini yapamwamba.
Zoletsa zomwe zilipo kale, kuphatikizapo kusindikiza katatu katatu, kumabweretsa kutsika kwambiri kwa zowonjezera ". Tekinoloje yatsopano, yotchedwa Fluth Hydrolitholitgraphy (yofinya wa hydrogel sproolitography kusindikiza, zomwe zimachepetsa katundu pa cell, yomwe chilengedwe chathandiza, chomwe chimakhala ndi njira zina zosindikizira 3.
Kusindikiza 3D kumapereka chiyembekezo chodzala ndi ziwalo zomwe zingabwezeretse ziwalo zopereka, ndipo ofufuzawo akuyembekeza kuti tsiku linanso ndi amene amapanga dongosolo lonse la Ojeli. Lingaliro ili nthawi zambiri limatanthawuza kusindikiza kwa matrix a Biociorgel omwe ali ndi maselo amoyo.
Komabe, njira yosindikiza imatha kukhala ndi zotsatira zoyipa pamaselo olowa m'malo, ndipo nthawi yayitali yosindikiza imangoyambitsa vutolo. Chifukwa cha kuthekera kosindikizidwa mwachangu kwa matrix a hydrogel, ukadaulo watsopano umathandiza maselo amoyo kuti akhale ndi moyo wosindikiza. Tekinoloje yogwira ntchito 10-5 kuchulukitsa mwachangu kwa mafakitale a mafakitale imakupatsani mwayi wopanga zitsanzo zazikulu, zomwe zimakhala zovuta kukwaniritsa.
Chifukwa cha kuwongolera kovuta kwa malo a Photopolymerization, ukadaulo ukhoza kupangidwa ndi matrimes a hydrogel a sentimeter kukula kwa mphindi. Gululi linayesanso kuthekera kupikisana ndi ma cell ndi zomangira zamagazi mitsempha, zomwe zingafunike kugwira ntchito koyenera kwa ziwalo zosindikizidwa za 3D. Ma netiweki a mitsempha yamagazi mu hydrogel amalola yankho la michere kuti lilowe mu matrix, chomwe ndi chinthu chofunikira kupeza ziwalo zosindikizidwa.
