ABD\u2019nin Tufts \u00dcniversitesi\u2019nde \u00e7al\u0131\u015fan bilim insanlar\u0131, efsanevi \u00e7izgi roman kahraman\u0131 \u00d6r\u00fcmcek Adam\u2019\u0131n f\u0131rlatt\u0131\u011f\u0131na benzer bir a\u011f \u00fcretti.<\/p>\n

2020 y\u0131l\u0131nda biyomedikal m\u00fchendisli\u011fi alan\u0131nda ara\u015ft\u0131rma g\u00f6revlisi olan Marco Lo Presti, su alt\u0131 yap\u0131\u015ft\u0131r\u0131c\u0131lar\u0131 \u00fczerine \u00e7al\u0131\u015f\u0131yordu. Midyelerin su alt\u0131nda kayalara s\u0131k\u0131ca yap\u0131\u015fmas\u0131ndan yola \u00e7\u0131kan Lo Presti, ipek ve dopamin kar\u015f\u0131m\u0131n\u0131n benzer bir etkisi oldu\u011funu g\u00f6rd\u00fc. \u015eans eseri fark etti<\/strong> Deneylerden sonra kar\u0131\u015f\u0131m\u0131n\u0131 t\u00fcplerden asetonla temizleyen Lo Presti, ipek ve dopaminin asetonla temas\u0131ndan sonra kat\u0131 bir formata, a\u011f benzeri, elyaf gibi g\u00f6r\u00fcnen bir malzemeye d\u00f6n\u00fc\u015ft\u00fc\u011f\u00fcn\u00fc fark etti. Bunu \u00e7al\u0131\u015ft\u0131\u011f\u0131 Silklab\u2019in patronu olan Profes\u00f6r Fiorenzo Omenetto\u2019ya g\u00f6steren Lo Presti, s\u00fcper g\u00fc\u00e7leri taklit eden bir malzemenin her zaman \u00e7ok iyi oldu\u011funu d\u00fc\u015f\u00fcnd\u00fcklerini belirtti. A\u011f atma evrimi Lo Presti ve meslekta\u015flar\u0131n\u0131n ince bir ipek fibroin ve dopamin kombinasyonunu bir i\u011fne arac\u0131l\u0131\u011f\u0131yla p\u00fcsk\u00fcrtmeleriyle ba\u015flad\u0131. Bu, ba\u015flang\u0131\u00e7ta do\u011frudan aseton banyosuna at\u0131l\u0131yordu ve bu da maddenin kat\u0131la\u015farak bir hidrojele d\u00f6n\u00fc\u015fmesini tetikliyordu. Ekip daha sonra asetonu, i\u00e7 i\u011fne katman\u0131ndaki ipe\u011fi ve dopamini \u00e7evreleyerek s\u0131v\u0131n\u0131n do\u011frudan havaya f\u0131rlamas\u0131n\u0131 sa\u011flayan koaksiyel i\u011fnenin d\u0131\u015f katman\u0131na eklemeye karar verdi. Aseton havada buharla\u015ft\u0131k\u00e7a, dopamin maddenin kat\u0131la\u015fma s\u00fcrecini h\u0131zland\u0131rd\u0131 ve ipekten suyu \u00e7ekerek yap\u0131\u015fkan, g\u00fc\u00e7l\u00fc, e\u011frilmi\u015f lifler olu\u015fturdu. Daha sonra liflere daha fazla \u00e7ekme mukavemeti kazand\u0131rmak i\u00e7in kitosan ve biyopolimer nesnelere yap\u0131\u015fma \u00f6zelli\u011fini art\u0131rmak i\u00e7in borat tamponu eklendi. Kullan\u0131labilir duruma geldi<\/strong> Marco Lo Presti, art\u0131k 30-35 santimetre mesafedeki bir nesneyi yakalay\u0131p, 15-20 gram a\u011f\u0131rl\u0131\u011f\u0131nda nesnelerin kald\u0131r\u0131labildi\u011fini aktard\u0131. Deneyler sonucunda ipek liflerle, su \u00fczerinde y\u00fczen bir deney t\u00fcp\u00fc ve k\u0131smen kuma g\u00f6m\u00fclm\u00fc\u015f paslanmaz \u00e7elik bir ne\u015fter uzaktan al\u0131nabildi. Binalardan sallanabilecek miyiz?<\/strong> Profes\u00f6r Omenetto \u201cHerkes binalardan sallan\u0131p sallanamayaca\u011f\u0131m\u0131z\u0131 bilmek istiyor. Hen\u00fcz orada de\u011filiz. Ancak su alt\u0131nda kaybolan bir nesnenin kurtar\u0131lmas\u0131nda veya uzaktan nesneleri yakalayabilen bir drone yap\u0131m\u0131nda kullan\u0131labilir\u201d \u015feklinde konu\u015ftu. Do\u011fal ipe\u011fin \u00e7ok g\u00fc\u00e7l\u00fc, sert oldu\u011funa ve b\u00fcy\u00fck a\u011f\u0131rl\u0131klar\u0131 kald\u0131rabilece\u011fine dikkat \u00e7eken Omenetto, kendi bulu\u015flar\u0131n\u0131n da bu seviyeye gelebilece\u011fini umduklar\u0131n\u0131 aktard\u0131.
