Kusintha kwa sayansi pakupanga mafupa

Gulu la ofufuza lapanga njira yatsopano yolumikizira mafupa, yomwe imalimbikitsidwa ndi mapiko a dragonflies, cicadas, kapena cicadas.

Chophimba chatsopanocho chimadziwika ndi chakuti chimachotsa mabakiteriya owopsa ndipo amatha kuchenjeza za kulephera kwapakhomo, malinga ndi zomwe zinafalitsidwa ndi webusaiti ya New Atlas, pogwira mawu magazini a Science.

Kuyerekeza kwachilengedwe

Biomimicry, ndiko kuti, kupanga zinthu zopangidwa ndi anthu potengera zomwe zachitika m'chilengedwe, yakhala ikuyendetsa mphamvu zatsopano m'magulu azachipatala kwa zaka zambiri.

Chinthu chomwe chingapangitse mafupa abwino a mafupa apangidwa kale, ouziridwa ndi mitundu yosiyanasiyana ya pores yomwe imapezeka mumitengo ndi nyanga za nyama.

Palinso sensa yopangidwa ndi cactus yomwe imatha kusonkhanitsa thukuta kuti liwunikenso ndikuphimba kuti ubongo ugwire ntchito motengera masamba a chomera chodya nyama.

Kubwereranso ku kutsanzira chilengedwe, ofufuza ochokera ku yunivesite ya Illinois akhala akufufuza mapiko olimbana ndi mabakiteriya a dragonflies ndi cicadas kuti apange zinthu zatsopano zomwe zingathandize kuthetsa mavuto a tizilombo toyambitsa matenda omwe amapezeka kawirikawiri m'mitsempha ya mafupa.

Chinthu chogwira ntchito

Malinga ndi wofufuza wamkulu wa kafukufukuyu, Pulofesa wa University of Illinois of Materials Science and Engineering Cheng Kau, panalibe njira yoyenera yothanirana ndi matenda omwe amakhudza mpaka 10% ya odwala oyika mafupa ndi mafupa.

Pulofesa Cao adati zoyesayesa zamakono zogwiritsa ntchito ayoni olemera kwambiri polimbana ndi mabakiteriya zimathanso kuwononga minyewa yapafupi, ndipo ma implants okhala ndi maantibayotiki pamapeto pake amalephera pamene mankhwala amatha.

Komanso sizothandiza polimbana ndi mabakiteriya osamva maantibayotiki, omwe ndi vuto lomwe likukulirakulira m'zachipatala.

njira yamakina

Chifukwa chake Cao ndi gulu lake lofufuza adapanga chophimba chojambula chojambula chamankhwala, chokhala ndi mbali imodzi ya nanobeams ngati zomwe zimapezeka pamapiko a tizilombo omwe amapha maselo a bakiteriya akakumana nawo.

"Kugwiritsa ntchito makina ophera mabakiteriya kumapangitsa kuti mavuto ambiri ndi njira zama mankhwala apitirire, pomwe akupereka kusinthasintha kofunikira kuti agwiritse ntchito zokutira pamalo otukuka," atero Pulofesa Jie Lau, Pulofesa wa Pathology Biology, wolemba nawo bukuli. kuphunzira.

Awiri mwa mmodzi

Ofufuzawo sanangothetsa vuto limodzi ndi ma implants a mafupa, adazindikira kuti zokutira zawo zimatha kuthetsa wina: kuzindikira koyambirira kwa kulephera kwa implant.

Cao anafotokoza kuti vutoli limakhudzanso pafupifupi 10 peresenti ya odwala onse omwe amawaika.

Ofufuzawo adayika ma microsensors osinthika kumbali ina ya zokutira zomwe zimatha kuyeza kupsinjika kwamakina pama implants, pomwe zokutira zidayikidwa. Ochita kafukufuku amanena kuti zimathandiza madokotala kuti awone momwe thupi limachiritsira pafupi ndi implant, ndipo amatha kutumiza zidziwitso ngati kupanikizika kwa mgwirizano wochita kupanga kuli kwakukulu. Ofufuzawa akugwira ntchito pa njira yopanda zingwe kuti apereke mphamvu yakunja yopangira zokutira.
