Gulu la asayansi ku Massachusetts Institute of Technology ndi Stevens Institute of Technology ku New Jersey lapanga luso lapamwamba kwambiri losindikiza la 3D. Osindikiza ochiritsira a 3D amatha kusindikiza zinthu zazing'ono ngati ma microns 150. Ukadaulo womwe waperekedwa ku MIT umatha kusindikiza chinthu cha 10 microns wandiweyani. Kulondola kotereku sikofunikira kwenikweni pakugwiritsa ntchito kwambiri posindikiza za 3D, koma zikhala zothandiza kwambiri pakufufuza zamankhwala ndi zamankhwala komanso kulonjeza zopambana m'magawo awa.
Chowonadi ndi chakuti masiku ano, kunena pang'ono, magawo awiri-dimensional amagwiritsidwa ntchito kukulitsa zikhalidwe zama cell. Momwe komanso momwe ma cell amakulira pazigawo zotere ndi nkhani yamwayi. Pazifukwa zotere, ndizosatheka kuwongolera molondola mawonekedwe ndi kukula kwa koloni yowonjezera. Chinanso ndi njira yatsopano yopangira gawo lapansi. Kuchulukitsa kusamvana kwa kusindikiza kwa 3D pamlingo wa cell kumatsegula njira yopangira ma cell okhazikika kapena ma porous, mawonekedwe ake omwe angatsimikizire bwino kukula ndi mawonekedwe a cell yamtsogolo. Ndipo kuwongolera mawonekedwe kumatsimikizira kwambiri zomwe ma cell ndi koloni yonse. Nanga bwanji madera? Ngati mupanga gawo lapansi mu mawonekedwe a mtima, chiwalo chimakula chomwe chimawoneka ngati mtima, osati chiwindi.
Tiyeni tisungire kusungitsa kuti pakadali pano sitikunena za ziwalo zomwe zimakula, ngakhale ochita kafukufuku amawona kuti ma cell tsinde amakhala nthawi yayitali pama cell opangidwa ndi ma cell a micrometer kuposa gawo laling'ono. Makhalidwe a magulu a maselo okhala ndi katundu wosiyana pa gawo latsopano la magawo atatu akuphunziridwa. Zowona zikuwonetsa kuti mamolekyu a protein a cell amapanga zomatira zodalirika pofika kumamatira ku gawo lapansi komanso kwa wina ndi mzake, kuwonetsetsa kukula kwa koloni mu kuchuluka kwa gawo lapansi.
Kodi asayansi adatha bwanji kukulitsa kusamvana kwa kusindikiza kwa 3D? Monga tafotokozera m'nkhani yasayansi mu nyuzipepala ya Microsystems ndi Nanoengineering, ukadaulo wosungunula ma electrowriting wathandizira kukulitsa kusamvana. Pochita, gawo lamphamvu lamagetsi lamagetsi limayikidwa pakati pa mutu wosindikizira wa 3D wosindikiza ndi gawo lapansi losindikizira lachitsanzo, zomwe zidathandizira kuphwanya ndi kuwongolera mwanjira inayake zinthu zosungunula zomwe zimatuluka m'milomo yosindikiza. Tsoka ilo, palibe zina zomwe zaperekedwa.
