Abstract
copolímero de dibloco e usos dos mesmos descritos aqui são copolímeros, e métodos de preparar e utilizar tais copolímeros. tais copolímero têm pelo menos dois blocos: um primeiro bloco que tem pelo menos uma unidade que é hidrofílica em ph fisiológico, e um segundo bloco que tem grupos hidrofóbicos. este segundo bloco também tem pelo menos uma unidade com um grupo que é aniônico em cerca de ph fisiológico. os copolímeros descritos são disruptivos de uma membrana celular, incluindo uma membrana extracelular, uma membrana intracelular, uma vesícula, uma organela, um endossoma, um lipossoma, ou uma célula de eritrócito. preferivelmente, em certos exemplos, o copolímero rompe a membrana e entra no ambiente intracelular. em exemplos específicos, o copolímero é endossomolítico.
