Abstract
Description
도 2는 암세포와 정상세포에 농도와 시간을 변화시키면서 pH 민감성 금속 나노입자를 배양한 후 관찰한 암시야 현미경 사진이다.
도 3은 pH 민감성 금 나노 입자의 표면 분자체에 Alexa Fluor 488 hydrazide를 도입한 결합체 용액(흑색)과 여기에 KCN을 첨가하여 금나노 입자만을 선택적으로 녹여낸 용액(적색)의 흡광(좌측) 및 형광스펙트럼(우측).
도 4는 pH 민감성 금 나노 입자와 Alexa Flour 488 hydeazide 결합체를 pH 7.6(흑색), pH 1.0(적색) 수용액에 분산시킨 후 측정한 흡광(좌측) 및 형광(우측) 스펙트럼.
도 5는 pH 민감성 금 나노 입자와 Alexa Fluor 488 hydrazide 결합체를 함께 배양한 후, 측정한 쥐 흑색종 세포의 형광 현미경 사진이며, 왼쪽 위편에서부터 시계 방향으로 세포에 처리한 지 각각 10분, 30분, 3시간, 1시간 경과 후 측정한 사진이다.
도 6은 pH 민감성 금 나노 입자와 doxorubicine의 결합체를 함께 배양한 유방암 세포 실험군(중간열)과 pH 민감성 금나노 입자(좌측열) 및 doxorubicine(우측열)을 함께 배양한 대조군의 시간에 따른 형광 현미경 사진이다. Doxorubicine이 세포내로 전달되면, doxorubicine의 형광에 의해 세포의 핵이 주황색으로 염색되어 보이게 된다. 배양 시간은 좌측에 표시하였다.
도 7은 pH 민감성 금 나노 입자의 표면 분자체와의 결합체 형성 모식도이다.
