Antibacterial polypeptides as ancient immune defense systems are effective against bacteria. Here we report a novel kind of "armed" carrier: an antibacterial polypeptide-grafted chitosan-based nanocapsule with an excellent antibacterial efficacy against both Gram-positive and Gram-negative bacteria. This nanocapsule also has excellent blood compatibility and low cytotoxicity. Patients after tumor surgery may benefit from this "armed" carrier because it is highly anti-inflammation and is able to deliver anticancer and antiepileptic drugs simultaneously.
抗菌多肽作为古老的免疫防御系统,对细菌有效。在此,我们报道了一种新型的“武装”载体:一种抗菌多肽接枝的壳聚糖基纳米胶囊,对革兰氏阳性菌和革兰氏阴性菌均具有优异的抗菌效果。这种纳米胶囊还具有优异的血液相容性和低细胞毒性。肿瘤手术后的患者可能会从这种“武装”载体中受益,因为它具有高度的抗炎性,并且能够同时递送抗癌和抗癫痫药物。
