제목 pH-responsive Eudragit® nanofiber for anti-bacterial activity by controlled release of tetracycline
초록 Electrospun nanofibrous mats for pH-dependent anti-bacterial activity were fabricated with two Eudragit® polymers with opposite charges. Eudragit® EPO (EEPO) having dimethylamino group and Eudragit® L100 (EL100) having carboxylate were co-electrospun with tetracycline (Tet) and subsequently complexed at the tip of co-axial needle during the electrospinning process. The composition of the respective polymer was conveniently adjusted by changing the flow rate ratios of EL100 (outlet) and EEPO (inlet). In pH 2.0 buffer, NF with higher EEPO contents was dissolved rapidly. Also, higher EEPO composition in NF accelerated release of Tet in pH 2.0 and pH 6.0. The release fractions from higher EEPO composition NF was more successfully inhibited the growth of E.coli in pH2 and pH6. In conclusion, the Eudragit® nanofiber was successfully controlled the release of Tet by complexation of oppositely-charged EL100 and EEPO.
