Yeni teknolojinin en heyecan verici uygulama alan\u0131 ise insan v\u00fccudunun en korunakl\u0131 ve gizemli b\u00f6lgelerinden biri olan kan-beyin bariyeri oldu. Beyni zararl\u0131 maddelerden koruyan bu bariyer, ne yaz\u0131k ki Alzheimer ve ALS gibi hastal\u0131klar\u0131n tedavisinde kullan\u0131lan ila\u00e7lar\u0131n da beyne ula\u015fmas\u0131n\u0131 zorla\u015ft\u0131r\u0131yor.<\/p>\n\n\n\n
