Ib pab neeg ntawm cov kws tshawb fawb ntawm Massachusetts Institute of Technology thiab Stevens Institute of Technology hauv New Jersey tau tsim lub tshuab luam ntawv 3D siab heev. Pa 3D tshuab luam ntawv tuaj yeem luam cov khoom me me li 150 microns. Cov thev naus laus zis tau thov ntawm MIT muaj peev xwm luam tawm cov khoom 10 microns tuab. Xws li precision tsis yog xav tau rau kev siv dav hauv 3D luam ntawv, tab sis nws yuav muaj txiaj ntsig zoo rau kev tshawb fawb txog biomedical thiab kev kho mob thiab txawm cog lus tias yuav ua tiav hauv cov cheeb tsam no.
Qhov tseeb yog niaj hnub no, kuj hais lus, ob-seem substrates yog siv los loj hlob ntawm tes kab lis kev cai. Yuav ua li cas thiab yuav ua li cas cell colonies loj hlob ntawm xws li substrates yog qhov teeb meem loj ntawm lub caij nyoog. Nyob rau hauv cov xwm txheej zoo li no, nws tsis yooj yim sua kom tswj cov duab thiab qhov loj ntawm cov colony nthuav. Lwm qhov yog txoj kev tshiab ntawm kev tsim cov substrate substrate. Ua kom cov kev daws teeb meem ntawm 3D luam ntawv mus rau lub xov tooj ntawm tes qhib txoj hauv kev rau kev tsim cov txheej txheem ntawm tes los yog ntxeem tau, cov duab uas yuav raug txiav txim siab qhov loj thiab qhov pom ntawm lub neej yav tom ntej ntawm tes. Thiab kev tswj daim ntawv yuav loj heev txiav txim siab lub zog ntawm cov hlwb thiab cov colony tag nrho. Yuav ua li cas yog colonies? Yog tias koj ua ib lub substrate nyob rau hauv cov duab ntawm lub plawv, lub cev yuav loj hlob zoo li lub plawv, tsis yog lub siab.
Cia peb ua ib qho kev tshwj tseg rau tam sim no peb tsis tau tham txog cov kabmob loj hlob, txawm hais tias cov kws tshawb fawb tau sau tseg tias cov qia hlwb nyob ntev dua ntawm cov substrates ua los ntawm cov cell loj dua li ntawm cov pa hauv qab. Tus cwj pwm ntawm cov cheeb tsam ntawm cov hlwb nrog cov khoom sib txawv ntawm ib qho tshiab peb-dimensional substrate tam sim no tau kawm. Kev soj ntsuam pom tau hais tias cov protein molecules ntawm cov hlwb tsim txhim khu kev qha focal adhesions ntawm qhov chaw ntawm adhesion rau lub substrate lattice thiab rau ib leeg, ua kom cov colony loj hlob nyob rau hauv lub ntim ntawm lub substrate qauv.
Yuav ua li cas cov kws tshawb fawb tuaj yeem txhim kho qhov kev daws teeb meem ntawm 3D luam ntawv? Raws li tau tshaj tawm nyob rau hauv ib tsab xov xwm tshawb fawb hauv phau ntawv xov xwm Microsystems thiab Nanoengineering, yaj electrowriting technology pab txhawb kev daws teeb meem. Nyob rau hauv kev xyaum, ib tug muaj zog electromagnetic teb tau thov nyob nruab nrab ntawm lub taub hau ntawm lub tshuab luam ntawv 3D thiab lub substrate rau luam ntawv tus qauv, uas pab tau crushed thiab nyob rau hauv ib txoj kev ncaj qha cov khoom molten gushing tawm ntawm lub taub hau nozzles. Hmoov tsis, tsis muaj lwm cov ntsiab lus qhia.
