I ka hoʻoikaika ʻana i ka hana ʻana i nā biomaterials i ʻoi aku ka maʻalahi, ua hoʻohui nā mea noiʻi ma ke Kulanui o Kaleponi, Berkeley i ka bioprinting 2D, kahi lima robotic no ka hui 3D, a me ka hoʻoheheʻe ʻana ma ke ʻano e hiki ai i kekahi lā ke paʻi i ka ʻiʻo ola a hiki. nā kino holoʻokoʻa. Ma ka paʻi ʻana i nā ʻōkana i loko o nā ʻāpana lahilahi o ka ʻiʻo, a laila hoʻomaloʻo iā lākou a hoʻopaʻa pū ʻia, hoʻomaikaʻi ka ʻenehana hou i ke ola ʻana o nā biocells i ka wā paʻi a i ka wā o ka mālama ʻana.
Nui ka mana o ka biomaterials no ka lāʻau lapaʻau e hiki mai ana. ʻO ka paʻi 3D me ka hoʻohana ʻana i nā pūnaewele ponoʻī o ka mea maʻi e kōkua i ka hana ʻana i nā okano no ka hoʻololi ʻana i kūpono piha a ʻaʻole e hōʻole ʻia.
ʻO ka pilikia, he lohi a ʻaʻole piʻi maikaʻi nā ʻano hana bioprinting i kēia manawa no ka mea paʻakikī nā cell i ke ola ʻana i ke kaʻina paʻi me ka ʻole o ka mālama paʻa ʻana i ka mahana a me ke kaiapuni. Eia kekahi, ʻoi aku ka paʻakikī o ka mālama ʻana a me ka lawe ʻana i nā lole i paʻi ʻia.
No ka lanakila ʻana i kēia mau pilikia, ua hoʻoholo ka hui Berkeley e hoʻohālikelike i ke kaʻina hana paʻi a hoʻokaʻawale iā ia i nā kaʻina hana. ʻO ia hoʻi, ma kahi o ka paʻi ʻana i kahi okana holoʻokoʻa i ka manawa hoʻokahi, paʻi ʻia nā ʻiʻo i ka manawa like i nā papa XNUMXD, a laila waiho ʻia e ka lima robotic e hana i ka hoʻolālā XNUMXD hope loa.
ʻO kēia ala ke wikiwiki nei i ke kaʻina hana, akā no ka hōʻemi ʻana i ka make cell, hoʻokomo koke ʻia nā papa i loko o ka ʻauʻau cryogenic e hoʻokuʻu iā lākou. Wahi a ka hui, hoʻomaikaʻi nui kēia i nā kūlana no ke ola ʻana o nā mea i paʻi ʻia i ka wā mālama a me ka lawe ʻana.
"I kēia manawa, hoʻohana nui ʻia ka bioprinting e hana i nā liʻiliʻi liʻiliʻi o nā kiko," wahi a Boris Rubinsky, ke kaukaʻi o ka ʻenekinia mechanical. “ʻO ka pilikia me ka bioprinting 3D he hana lohi loa ia, no laila ʻaʻole hiki iā ʻoe ke paʻi i kekahi mea nui no ka mea e make nā mea olaola i ka manawa āu e pau ai. ʻO kekahi o kā mākou hana hou, ʻo ia ka hoʻokuʻu ʻana i ka ʻiʻo ke paʻi ʻia, no laila mālama ʻia ka mea ola."
Ua ʻae ka hui ʻaʻole hou kēia ʻano multilayer i ka paʻi 3D, akā ʻo kāna noi i nā biomaterials he mea hou. ʻAe kēia e paʻi ʻia nā papa ma kekahi wahi a laila lawe ʻia i kahi ʻē aʻe no ka hui ʻana.
Ma waho aʻe o ka hana ʻana i nā ʻiʻo a me nā ʻāpana, loaʻa i kēia ʻenehana nā noi ʻē aʻe, e like me ka hana ʻana i ka meaʻai hau hau ma kahi ʻano ʻoihana.
Ua paʻi ʻia ka haʻawina ma .
