JAV mokslininkai pagamino nanodaleles, kurios imituoja svarbiausias raudon\u0173j\u0173 kraujo k\u016bneli\u0173 – eritrocit\u0173 – savybes, prane\u0161\u0117 \u0160iaur\u0117s Karolinos universitetas (JAV). Pasak mokslinink\u0173, \u0161is pasiekimas yra svarbus \u017eingsnis \u012f priek\u012f kuriant sintetin\u012f krauj\u0105. <\/o:p><\/span><\/p>\n

\u0160iaur\u0117s Karolinos universiteto mokslininkai, vadovaujami profesoriaus Josepho DeSimone’o, i\u0161rado PRINT (Particle Replication in Non-wetting Templates) technologij\u0105, leid\u017eian\u010di\u0105 gaminti labai mink\u0161tas hidrogelio daleles, imituojan\u010dias eritrocit\u0173 dyd\u012f, form\u0105 ir elastingum\u0105.<\/o:p><\/span><\/p>\n

Kol kas eritrocit\u0173 funkcij\u0173 – geb\u0117jimo perne\u0161ti deguon\u012f ir gydom\u0105sias med\u017eiagas – bandymai nebuvo atliekami, sakoma universiteto prane\u0161ime. \u017dinoma tik tiek, kad sintetin\u0117s kraujo dalel\u0117s organizmo \u0161irdies ir kraujagysli\u0173 sistemoje <\/a>i\u0161lieka beveik tiek pat, kiek ir tikrieji eritrocitai.<\/o:p><\/span><\/p>\n

JAV mokslininkai \u0161\u012f i\u0161radim\u0105 laiko dideliu pasiekimu d\u0117l to, kad jiems pavyko sukurti itin elastingas daleles, galin\u010dias prasiskverbti pro mikroskopines \u017emogaus organ\u0173 poras ir siauras kraujagysles. Tik gyvenimo pabaigoje \u0161ios dalel\u0117s tampa kietesn\u0117s ir jau nebegali \u012fveikti filtruojan\u010di\u0173 kepen\u0173 audini\u0173<\/a>.<\/o:p><\/span><\/p>\n

Eritrocitai gyvena apie 120 dien\u0173, o bandym\u0173 su laboratorin\u0117mis pel\u0117mis metu dirbtini\u0173 kraujo k\u016bneli\u0173 skilimo pusperiodis siek\u0117 93 valandas. Dirbtinius kraujo k\u016bnelius i\u0161 organizmo \u0161alino kepenys, sakoma prane\u0161ime.<\/o:p><\/span><\/p>\n

Video parodyta kaip dirbtiniai eritrocitai keliauja pro 3 mikrometr\u0173 skersmens kanal\u0117l\u012f. Taip specialiame aparate tikrinamas j\u0173 lankstumas. Matomos dalel\u0117s prie\u0161 tai pralindo pro beveik 50 toki\u0173 kanal\u0117li\u0173 ir neprarado savo formos ar elastingumo.<\/o:p><\/span><\/p>\n
