Matenda aubongo ndiwovuta kusangalalira osati chifukwa ndi chiwalo chovuta kwambiri cha thupi lathu. Ndiwotetezedwanso: ngakhale mitsempha yamagazi siyigwirizanitsidwa ndi minofu ya chapakati mantha dongosolo, kulekanitsa ndi iwo ndi maselo a chotchinga cha hematostefalic. Kukhazikika kwa BGB kumasankha: oxygen ndi michere imadutsa, koma samaphonya poizoni, ma virus ndi othandizira ena oopsa. Komabe, sizilola kufika ku ubongo ndi zinthu zosiyanasiyana zinthu zopindulitsa.
Sizikudabwitsa kuti asayansi amakumana ndi njira zothanirana ndi BBB: Mwachitsanzo, nanoparticles omwe amatha kulowa ma cell a ubongo, akupereka mankhwala mkati ndikumasulidwa. Ndipo gulu la Zhiganana (Zhiiguang Wu) kuchokera ku Harbin University yatola ndi microbot yonseyi. Anakambirana za chitukuko chake m'nkhani yomwe inafalitsidwa mu magazini ya sayansi.
Asayansi amatcha kachitidwe kake "Newrobot", chifukwa cha msonkhano, zidutswa za Neutrophils, matule amthupi amagwiritsidwa ntchito. Zimachitika motere. Poyamba, olembawo adakonza microscopic ndi zotanuka za "Magnetic Nangel": Malingaliro awo a polymer, omwe ali ndi mphamvu yamagetsi, amatha kupeza madzi ochulukirapo limodzi ndi mankhwala ofunikira. Kenako, maselo a mabakiteriya a zipatso zamatumbo adaphedwa ndikuti "kuzikika", kuchotsa chilichonse chokha ndikusiya zidutswa chabe za ma cell membrane. Adaphimba zigawo za Gel.
Chitetezo cha chitetezo cha mabakiteriya "ngati chibwibwi chofiyira." Chifukwa chake, tinthu tazikonzedwa tinkaphatikizika ndi neutrophils, adawazunza ndipo pa Pulogalamuytosis idachitidwa, imatenga chinthu chowopsa. Chifukwa cha maginito a nangel, kuyenda kwawo kumatha kulamulidwa ndi mphamvu yakunja yakuwongolera maselo anu mu ubongo. Kudzera mu BC neutrophils amatha kudutsa mosavuta komanso modziyimira pawokha, podzikopera chizindikiro kuchokera ku ubongo wa wodwala. Ndili ndi inu, amanyamula katundu wazamankhwala.
Maluso awo a "netlerobuts" awo adaonekera kokha "mu chubu choyesera", komanso mbewa ya labotale - mzere wachitsanzo, zomwe zimagwiritsidwa ntchito pophunzira Glyhoma, zotupa za ubongo. Tinthu tating'onoting'ono tating'onoting'ono timadzaza ndi paklitaxel, yoyikidwa mu bakisi ya ma bakisiriya ndi neutrophils, kenako "zopangidwa kale" zimalowetsedwa mu mtsempha wa mchira. Posakhalitsa anakonzanso kuti anthu amene anathetsa bc ndikupereka mankhwala mu minofu ya chapakati mantha dongosolo.
Tsopano olembawo akufuna kuchita nawo kukonzanso ndi kusintha kwa dongosolo lawo. Choyamba, asayansi ali ndi chidwi ndi njira yogwiritsira ntchito magwero a "netlerobuts" ndikuwongolera mayendedwe awo. Pomwe mphamvu yamagalasi imayamba kwambiri, ndikuwongolera mu mbali yofunikira kwambiri ma microscopic a microscopic ma microscopic.
