Cov kws tshawb fawb hauv University of Toronto tau tsim lub tshuab luam ntawv 3D ua lub hnab tawv nqaij uas tuaj yeem pab kho qhov mob tob. Nws yog thawj lub cuab yeej muaj peev xwm tsim cov ntaub so ntswg, tso nyiaj thiab teeb tsa hauv qhov chaw hauv ob feeb lossis tsawg dua. Txoj kev tshawb nrhiav, coj los ntawm tub ntxhais kawm Navid Hakimi, coj los ntawm Associate Professor Axel Gunther, tau luam tawm hauv Lab ntawm Chip.
Thaum lub qhov txhab tob ua rau daim tawv nqaij, tag nrho peb txheej ntawm daim tawv nqaij - epidermis, dermis, thiab hypodermis - tuaj yeem puas ntsoog. Txoj kev kho tam sim no yog qhov kev tshem tawm ntawm daim tawv nqaij pob txha mos, uas yog ib feem ntawm cov tawv nqaij noj qab haus huv tau muab faus rau cov txheej txheem sab nraud thiab ib feem ntawm cov tawv nqaij mob.
Daim tawv nqaij pleev rau cov qhov txhab loj yuav tsum muaj tawv nqaij txaus los ntawm tus neeg pub noj qab haus huv kom npog tag nrho peb txheej, yog li nws tsis tshua muaj peev xwm ua nyob rau ntawm qhov chaw. Feem ntau ntawm cov npoo npog tseem "npog", uas ua rau cov txiaj ntsig tsis zoo.
Txawm hais tias muaj ntau heev qee daim tawv nqaij hloov chaw, lawv tseem tsis tau siv dav hauv chaw kho mob.

Gunther piav qhia tias "3D bioprinters feem ntau niaj hnub tua, qeeb, kim, thiab tsis txuam nrog kev siv tshuaj," piav qhia Gunther.
Cov kws tshawb fawb ntseeg tias lawv lub tshuab luam ntawv yog lub platform uas muaj peev xwm hla dhau cov kev cuam tshuam no thiab txhim kho cov tawv nqaij kho kom zoo. Lub tshuab luam ntawv lub hnab tshos zoo ib yam li daim ntawv tso zis tso quav, tshwj tsis yog ntawv yob, nws muaj cov khoom siv me me uas ua rau cov ntawv so ntswg. Cov kab ke ntsug ntawm "bio-number case", ua los ntawm cov proteinaceous biomaterials zoo li collagen thiab fibrin, sau ua ke txhua lub lamina ntawm daim tawv nqaij. Lub tshuab luam ntawv tau thauj khoom tau yooj yim thiab cog lus tias yuav yoog tau txhua tus neeg mob tus yam ntxwv thiab mob qhov txhab.
Cov khau me-thawv-cov khoom ntaus ntawv hnyav dua li ib phaus thiab yuav tsum muaj cov neeg ua haujlwm tsawg kawg nkaus. Cov kws tshawb fawb kev cia siab tias muaj ib hnub lawv tuaj yeem pib soj ntsuam kev kho mob hauv tib neeg thiab sawv tawm tsam kev coj noj coj ua los kho kev kub nyhiab.
