“…Aqueous solutions of these short chain gelators have exhibited a pH-and temperature-responsive sol-gel transition, with the gel windows occurring under physiological conditions. For therapeutic applications, these polymers and oligomers may be potential carriers for the delivery of various types of drugs or proteins such as doxorubicin [111,118], human growth hormone [112], lidocaine [115], chlorambucil [109,113], FITC-BSA [110], paclitaxel [108], and insulin [117].…”
