Zusammenfassung:The present invention relates to a drug carrier with improved cancer cell targeting ability and increased drug carrying efficiency that can be used for cancer tracking and treatment, and a method for manufacturing the same. More specifically, the present invention relates to a drug carrier in which a micelle structure is formed using a block copolymer having a disulfide bond and then perfluorocarbon is injected into the micelle, and a method for manufacturing the same. The drug carrier's simultaneous response to ultrasound and glutathione to promote decomposition of the hydrophobic part of the block copolymer polymer, which is a drug carrier, by the chemical action of glutathione, and the mechanism of drug release by the physical action of ultrasonic waves are combined, thereby providing a synergistic effect that can maximize drug release. 본원 발명은 암 추적 및 치료에 이용할 수 있는 암세포 타겟팅 능력 향상과 약물 전달 효율이 증대된 약물전달체 및 이의 제조방법에 대한 것이다. 보다 구체적으로는 다이설파이드(disulfide) 결합을 가지는 블록공중합체를 이용하여 마이셀(micelle) 구조를 형성시킨 후 마이셀의 내부에 퍼플루오로카본(perfluorocarbon)을 주입한 약물전달체 및 이의 제조방법에 대한 것이다. 본원발명에 따른 약물전달체는 초음파와 글루타사이온에 동시에 감응하여 글루타사이온의 화학작용에 의한 약물전달체인 블록공중합 고분자의 소수성 부분이 분해의 촉진 및 초음파에 의한 물리적 작용에 의한 약물 방출의 메커니즘의 융합되어 약물방출을 극대화 할 수 있는 시너지 효과가 있다.
